       ack-grep - grep-like text finder


           ack-grep [options] PATTERN [FILE...]
           ack-grep -f [options] [DIRECTORY...]


       Ack is designed as a replacement for 99% of the uses of grep.

       Ack searches the named input FILEs (or standard input if no files are named, or the file
       name - is given) for lines containing a match to the given PATTERN.  By default, ack-grep
       prints the matching lines.

       PATTERN is a Perl regular expression.  Perl regular expressions are commonly found in
       other programming languages, but for the particulars of their behavior, please consult
       <|perlreref>.  If you don't know how to use regular
       expression but are interested in learning, you may consult
       <|perlretut>.  If you do not need or want ack-grep
       to use regular expressions, please see the "-Q"/"--literal" option.

       Ack can also list files that would be searched, without actually searching them, to let
       you take advantage of ack-grep's file-type filtering capabilities.


       If files are not specified for searching, either on the command line or piped in with the
       "-x" option, ack-grep delves into subdirectories selecting files for searching.

       ack-grep is intelligent about the files it searches.  It knows about certain file types,
       based on both the extension on the file and, in some cases, the contents of the file.
       These selections can be made with the --type option.

       With no file selection, ack-grep searches through regular files that are not explicitly
       excluded by --ignore-dir and --ignore-file options, either present in ackrc files or on
       the command line.

       The default options for ack ignore certain files and directories.  These include:

       •   Backup files: Files matching #*# or ending with ~.

       •   Coredumps: Files matching core.\d+

       •   Version control directories like .svn and .git.

       Run ack-grep with the "--dump" option to see what settings are set.

       However, ack-grep always searches the files given on the command line, no matter what
       type.  If you tell ack-grep to search in a coredump, it will search in a coredump.


       ack-grep descends through the directory tree of the starting directories specified.  If no
       directories are specified, the current working directory is used.  However, it will ignore
       the shadow directories used by many version control systems, and the build directories
       used by the Perl MakeMaker system.  You may add or remove a directory from this list with
       the --[no]ignore-dir option. The option may be repeated to add/remove multiple directories
       from the ignore list.

       For a complete list of directories that do not get searched, run "ack-grep --dump".


       ack-grep trumps grep as an everyday tool 99% of the time, but don't throw grep away,
       because there are times you'll still need it.

       E.g., searching through huge files looking for regexes that can be expressed with grep
       syntax should be quicker with grep.

       If your script or parent program uses grep "--quiet" or "--silent" or needs exit 2 on IO
       error, use grep.


           Specifies an ackrc file to load after all others; see "ACKRC LOCATION SEMANTICS".

       -A NUM, --after-context=NUM
           Print NUM lines of trailing context after matching lines.

       -B NUM, --before-context=NUM
           Print NUM lines of leading context before matching lines.

           Print a break between results from different files. On by default when used

       -C [NUM], --context[=NUM]
           Print NUM lines (default 2) of context around matching lines.

       -c, --count
           Suppress normal output; instead print a count of matching lines for each input file.
           If -l is in effect, it will only show the number of lines for each file that has lines
           matching.  Without -l, some line counts may be zeroes.

           If combined with -h (--no-filename) ack-grep outputs only one total count.

       --[no]color, --[no]colour
           --color highlights the matching text.  --nocolor suppresses the color.  This is on by
           default unless the output is redirected.

           On Windows, this option is off by default unless the Win32::Console::ANSI module is
           installed or the "ACK_PAGER_COLOR" environment variable is used.

           Sets the color to be used for filenames.

           Sets the color to be used for matches.

           Sets the color to be used for line numbers.

           Show the column number of the first match.  This is helpful for editors that can place
           your cursor at a given position.

           Dumps the default ack-grep options to standard output.  This is useful for when you
           want to customize the defaults.

           Writes the list of options loaded and where they came from to standard output.  Handy
           for debugging.

           --noenv disables all environment processing. No .ackrc is read and all environment
           variables are ignored. By default, ack-grep considers .ackrc and settings in the

           --flush flushes output immediately.  This is off by default unless ack-grep is running
           interactively (when output goes to a pipe or file).

       -f  Only print the files that would be searched, without actually doing any searching.
           PATTERN must not be specified, or it will be taken as a path to search.

           The list of files to be searched is specified in FILE.  The list of files are
           separated by newlines.  If FILE is "-", the list is loaded from standard input.

           Forces ack-grep to act as if it were receiving input via a pipe.

           Follow or don't follow symlinks, other than whatever starting files or directories
           were specified on the command line.

           This is off by default.

       -g PATTERN
           Print files where the relative path + filename matches PATTERN.  This option can be
           combined with --color to make it easier to spot the match.

           --group groups matches by file name.  This is the default when used interactively.

           --nogroup prints one result per line, like grep.  This is the default when output is

       -H, --with-filename
           Print the filename for each match. This is the default unless searching a single
           explicitly specified file.

       -h, --no-filename
           Suppress the prefixing of filenames on output when multiple files are searched.

           Print a filename heading above each file's results.  This is the default when used

       --help, -?
           Print a short help statement.

       --help-types, --help=types
           Print all known types.

       -i, --ignore-case
           Ignore case distinctions in PATTERN

           Tells ack-grep to completely ignore the default definitions provided with ack-grep.
           This is useful in combination with --create-ackrc if you really want to customize ack-

       --[no]ignore-dir=DIRNAME, --[no]ignore-directory=DIRNAME
           Ignore directory (as CVS, .svn, etc are ignored). May be used multiple times to ignore
           multiple directories. For example, mason users may wish to include --ignore-dir=data.
           The --noignore-dir option allows users to search directories which would normally be
           ignored (perhaps to research the contents of .svn/props directories).

           The DIRNAME must always be a simple directory name. Nested directories like foo/bar
           are NOT supported. You would need to specify --ignore-dir=foo and then no files from
           any foo directory are taken into account by ack-grep unless given explicitly on the
           command line.

           Ignore files matching FILTERTYPE:FILTERARGS.  The filters are specified identically to
           file type filters as seen in "Defining your own types".

       -k, --known-types
           Limit selected files to those with types that ack-grep knows about.  This is
           equivalent to the default behavior found in ack-grep 1.

           Only print line NUM of each file. Multiple lines can be given with multiple --lines
           options or as a comma separated list (--lines=3,5,7). --lines=4-7 also works. The
           lines are always output in ascending order, no matter the order given on the command

       -l, --files-with-matches
           Only print the filenames of matching files, instead of the matching text.

       -L, --files-without-matches
           Only print the filenames of files that do NOT match.

       --match PATTERN
           Specify the PATTERN explicitly. This is helpful if you don't want to put the regex as
           your first argument, e.g. when executing multiple searches over the same set of files.

               # search for foo and bar in given files
               ack-grep file1 t/file* --match foo
               ack-grep file1 t/file* --match bar

       -m=NUM, --max-count=NUM
           Stop reading a file after NUM matches.

           Print this manual page.

       -n, --no-recurse
           No descending into subdirectories.

       -o  Show only the part of each line matching PATTERN (turns off text highlighting)

           Output the evaluation of expr for each line (turns off text highlighting) If PATTERN
           matches more than once then a line is output for each non-overlapping match.  For more
           information please see the section "Examples of --output".

       --pager=program, --nopager
           --pager directs ack-grep's output through program.  This can also be specified via the
           "ACK_PAGER" and "ACK_PAGER_COLOR" environment variables.

           Using --pager does not suppress grouping and coloring like piping output on the
           command-line does.

           --nopager cancels any setting in ~/.ackrc, "ACK_PAGER" or "ACK_PAGER_COLOR".  No
           output will be sent through a pager.

           Prints all lines, whether or not they match the expression.  Highlighting will still
           work, though, so it can be used to highlight matches while still seeing the entire
           file, as in:

               # Watch a log file, and highlight a certain IP address
               $ tail -f ~/access.log | ack-grep --passthru

           Only works in conjunction with -f, -g, -l or -c (filename output). The filenames are
           output separated with a null byte instead of the usual newline. This is helpful when
           dealing with filenames that contain whitespace, e.g.

               # remove all files of type html
               ack-grep -f --html --print0 | xargs -0 rm -f

       -Q, --literal
           Quote all metacharacters in PATTERN, it is treated as a literal.

       -r, -R, --recurse
           Recurse into sub-directories. This is the default and just here for compatibility with
           grep. You can also use it for turning --no-recurse off.

       -s  Suppress error messages about nonexistent or unreadable files.  This is taken from

       --[no]smart-case, --no-smart-case
           Ignore case in the search strings if PATTERN contains no uppercase characters. This is
           similar to "smartcase" in vim. This option is off by default, and ignored if "-i" is

           -i always overrides this option.

           Sorts the found files lexicographically.  Use this if you want your file listings to
           be deterministic between runs of ack-grep.

           Outputs the filetypes that ack-grep associates with each file.

           Works with -f and -g options.

           Specify the types of files to include or exclude from a search.  TYPE is a filetype,
           like perl or xml.  --type=perl can also be specified as --perl, and --type=noperl can
           be done as --noperl.

           If a file is of both type "foo" and "bar", specifying --foo and --nobar will exclude
           the file, because an exclusion takes precedence over an inclusion.

           Type specifications can be repeated and are ORed together.

           See ack-grep --help=types for a list of valid types.

       --type-add TYPE:FILTER:FILTERARGS
           Files with the given FILTERARGS applied to the given FILTER are recognized as being of
           (the existing) type TYPE.  See also "Defining your own types".

       --type-set TYPE:FILTER:FILTERARGS
           Files with the given FILTERARGS applied to the given FILTER are recognized as being of
           type TYPE. This replaces an existing definition for type TYPE.  See also "Defining
           your own types".

       --type-del TYPE
           The filters associated with TYPE are removed from Ack, and are no longer considered
           for searches.

       -v, --invert-match
           Invert match: select non-matching lines

           Display version and copyright information.

       -w, --word-regexp
           Force PATTERN to match only whole words.  The PATTERN is wrapped with "\b"

       -x  An abbreviation for --files-from=-; the list of files to search are read from standard
           input, with one line per file.

       -1  Stops after reporting first match of any kind.  This is different from --max-count=1
           or -m1, where only one match per file is shown.  Also, -1 works with -f and -g, where
           -m does not.

           Display the all-important Bill The Cat logo.  Note that the exact spelling of
           --thpppppt is not important.  It's checked against a regular expression.

           Check with the admiral for traps.

THE .ackrc FILE

       The .ackrc file contains command-line options that are prepended to the command line
       before processing.  Multiple options may live on multiple lines.  Lines beginning with a #
       are ignored.  A .ackrc might look like this:

           # Always sort the files

           # Always color, even if piping to a another program

           # Use "less -r" as my pager
           --pager=less -r

       Note that arguments with spaces in them do not need to be quoted, as they are not
       interpreted by the shell. Basically, each line in the .ackrc file is interpreted as one
       element of @ARGV.

       ack-grep looks in several locations for .ackrc files; the searching process is detailed in
       "ACKRC LOCATION SEMANTICS".  These files are not considered if --noenv is specified on the
       command line.

Defining your own types

       ack-grep allows you to define your own types in addition to the predefined types. This is
       done with command line options that are best put into an .ackrc file - then you do not
       have to define your types over and over again. In the following examples the options will
       always be shown on one command line so that they can be easily copy & pasted.

       ack-grep --perl foo searches for foo in all perl files. ack-grep --help=types tells you,
       that perl files are files ending in .pl, .pm, .pod or .t. So what if you would like to
       include .xs files as well when searching for --perl files? ack-grep --type-add perl:ext:xs
       --perl foo does this for you. --type-add appends additional extensions to an existing

       If you want to define a new type, or completely redefine an existing type, then use
       --type-set. ack-grep --type-set eiffel:ext:e,eiffel defines the type eiffel to include
       files with the extensions .e or .eiffel. So to search for all eiffel files containing the
       word Bertrand use ack-grep --type-set eiffel:ext:e,eiffel --eiffel Bertrand.  As usual,
       you can also write --type=eiffel instead of --eiffel. Negation also works, so --noeiffel
       excludes all eiffel files from a search. Redefining also works: ack-grep --type-set
       cc:ext:c,h and .xs files no longer belong to the type cc.

       When defining your own types in the .ackrc file you have to use the following:


       or writing on separate lines


       The following does NOT work in the .ackrc file:

         --type-set eiffel:ext:e,eiffel

       In order to see all currently defined types, use --help-types, e.g.  ack-grep --type-set
       backup:ext:bak --type-add perl:ext:perl --help-types

       In addition to filtering based on extension (like ack-grep 1.x allowed), ack-grep 2 offers
       additional filter types.  The generic syntax is --type-set TYPE:FILTER:FILTERARGS;
       FILTERARGS depends on the value of FILTER.

           is filters match the target filename exactly.  It takes exactly one argument, which is
           the name of the file to match.


               --type-set make:is:Makefile

           ext filters match the extension of the target file against a list of extensions.  No
           leading dot is needed for the extensions.


               --type-set perl:ext:pl,pm,t

           match filters match the target filename against a regular expression.  The regular
           expression is made case insensitive for the search.


               --type-set make:match:/(gnu)?makefile/

           firstlinematch matches the first line of the target file against a regular expression.
           Like match, the regular expression is made case insensitive.


               --type-add perl:firstlinematch:/perl/

       More filter types may be made available in the future.


       For commonly-used ack-grep options, environment variables can make life much easier.
       These variables are ignored if --noenv is specified on the command line.

           Specifies the location of the user's .ackrc file.  If this file doesn't exist, ack-
           grep looks in the default location.

           This variable specifies default options to be placed in front of any explicit options
           on the command line.

           Specifies the color of the filename when it's printed in --group mode.  By default,
           it's "bold green".

           The recognized attributes are clear, reset, dark, bold, underline, underscore, blink,
           reverse, concealed black, red, green, yellow, blue, magenta, on_black, on_red,
           on_green, on_yellow, on_blue, on_magenta, on_cyan, and on_white.  Case is not
           significant.  Underline and underscore are equivalent, as are clear and reset.  The
           color alone sets the foreground color, and on_color sets the background color.

           This option can also be set with --color-filename.

           Specifies the color of the matching text when printed in --color mode.  By default,
           it's "black on_yellow".

           This option can also be set with --color-match.

           See ACK_COLOR_FILENAME for the color specifications.

           Specifies the color of the line number when printed in --color mode.  By default, it's
           "bold yellow".

           This option can also be set with --color-lineno.

           See ACK_COLOR_FILENAME for the color specifications.

           Specifies a pager program, such as "more", "less" or "most", to which ack-grep will
           send its output.

           Using "ACK_PAGER" does not suppress grouping and coloring like piping output on the
           command-line does, except that on Windows ack-grep will assume that "ACK_PAGER" does
           not support color.

           "ACK_PAGER_COLOR" overrides "ACK_PAGER" if both are specified.

           Specifies a pager program that understands ANSI color sequences.  Using
           "ACK_PAGER_COLOR" does not suppress grouping and coloring like piping output on the
           command-line does.

           If you are not on Windows, you never need to use "ACK_PAGER_COLOR".


   Vim integration
       ack-grep integrates easily with the Vim text editor. Set this in your .vimrc to use ack-
       grep instead of grep:

           set grepprg=ack-grep\ -k

       That example uses "-k" to search through only files of the types ack-grep knows about, but
       you may use other default flags. Now you can search with ack-grep and easily step through
       the results in Vim:

         :grep Dumper perllib

       Miles Sterrett has written a Vim plugin for ack-grep which allows you to use ":Ack"
       instead of ":grep", as well as several other advanced features.


   Emacs integration
       Phil Jackson put together an ack.el extension that "provides a simple compilation mode ...
       has the ability to guess what files you want to search for based on the major-mode."


   TextMate integration
       Pedro Melo is a TextMate user who writes "I spend my day mostly inside TextMate, and the
       built-in find-in-project sucks with large projects.  So I hacked a TextMate command that
       was using find + grep to use ack-grep.  The result is the Search in Project with ack-grep,
       and you can find it here:

   Shell and Return Code
       For greater compatibility with grep, ack-grep in normal use returns shell return or exit
       code of 0 only if something is found and 1 if no match is found.

       (Shell exit code 1 is "$?=256" in perl with "system" or backticks.)

       The grep code 2 for errors is not used.

       If "-f" or "-g" are specified, then 0 is returned if at least one file is found.  If no
       files are found, then 1 is returned.


       If ack-grep gives you output you're not expecting, start with a few simple steps.

   Use --noenv
       Your environment variables and .ackrc may be doing things you're not expecting, or
       forgotten you specified.  Use --noenv to ignore your environment and .ackrc.

   Use -f to see what files have been selected
       Ack's -f was originally added as a debugging tool.  If ack-grep is not finding matches you
       think it should find, run ack-grep -f to see what files have been selected.  You can also
       add the "--show-types" options to show the type of each file selected.

   Use --dump
       This lists the ackrc files that are loaded and the options loaded from them.  So for
       example you can find a list of directories that do not get searched or where filetypes are


   Use the .ackrc file.
       The .ackrc is the place to put all your options you use most of the time but don't want to
       remember.  Put all your --type-add and --type-set definitions in it.  If you like
       --smart-case, set it there, too.  I also set --sort-files there.

   Use -f for working with big codesets
       Ack does more than search files.  "ack-grep -f --perl" will create a list of all the Perl
       files in a tree, ideal for sending into xargs.  For example:

           # Change all "this" to "that" in all Perl files in a tree.
           ack-grep -f --perl | xargs perl -p -i -e's/this/that/g'

       or if you prefer:

           perl -p -i -e's/this/that/g' $(ack-grep -f --perl)

   Use -Q when in doubt about metacharacters
       If you're searching for something with a regular expression metacharacter, most often a
       period in a filename or IP address, add the -Q to avoid false positives without all the

   Use ack-grep to watch log files
       Here's one I used the other day to find trouble spots for a website visitor.  The user had
       a problem loading troublesome.gif, so I took the access log and scanned it with ack-grep

           ack-grep -Q /path/to/access.log | ack-grep -Q -B5 troublesome.gif

       The first ack-grep finds only the lines in the Apache log for the given IP.  The second
       finds the match on my troublesome GIF, and shows the previous five lines from the log in
       each case.

   Examples of --output
       Following variables are useful in the expansion string:

       $&  The whole string matched by PATTERN.

       $1, $2, ...
           The contents of the 1st, 2nd ... bracketed group in PATTERN.

           The string before the match.

           The string after the match.

       For more details and other variables see

       This example shows how to add text around a particular pattern (in this case adding _
       around word with "e")

  "\w*e\w*" quick.txt --output="$`_$&_$'"
           _The_ quick brown fox jumps over the lazy dog
           The quick brown fox jumps _over_ the lazy dog
           The quick brown fox jumps over _the_ lazy dog

       This shows how to pick out particular parts of a match using ( ) within regular

         ack-grep '=head(\d+)\s+(.*)' --output=' $1 : $2'
         input file contains "=head1 NAME"
         output  "1 : NAME"

   Why isn't ack-grep finding a match in (some file)?
       Probably because it's of a type that ack-grep doesn't recognize.  ack-grep's searching
       behavior is driven by filetype.  If ack-grep doesn't know what kind of file it is, ack-
       grep ignores the file.

       Use the "-f" switch to see a list of files that ack-grep will search for you.  You can use
       the "--show-types" switch to show which type ack-grep thinks each file is.

   Wouldn't it be great if ack-grep did search & replace?
       No, ack-grep will always be read-only.  Perl has a perfectly good way to do search &
       replace in files, using the "-i", "-p" and "-n" switches.

       You can certainly use ack-grep to select your files to update.  For example, to change all
       "foo" to "bar" in all PHP files, you can do this from the Unix shell:

           $ perl -i -p -e's/foo/bar/g' $(ack-grep -f --php)

   Can I make ack-grep recognize .xyz files?
       Yes!  Please see "Defining your own types".  If you think that ack-grep should recognize a
       type by default, please see "ENHANCEMENTS".

   There's already a program/package called ack.
       Yes, I know.

   Why is it called ack-grep if it's called ack?
       The name of the program is "ack".  Some packagers have called it "ack-grep" when creating
       packages because there's already a package out there called "ack" that has nothing to do
       with this ack.

       I suggest you make a symlink named ack that points to ack-grep because one of the crucial
       benefits of ack is having a name that's so short and simple to type.

       To do that, run this with sudo or as root:

          ln -s /usr/bin/ack-grep /usr/bin/ack

       Alternatively, you could use a shell alias:

           # bash/zsh
           alias ack=ack-grep

           # csh
           alias ack ack-grep

   What does ack mean?
       Nothing.  I wanted a name that was easy to type and that you could pronounce as a single

   Can I do multi-line regexes?
       No, ack-grep does not support regexes that match multiple lines.  Doing so would require
       reading in the entire file at a time.

       If you want to see lines near your match, use the "--A", "--B" and "--C" switches for
       displaying context.

   Why is ack-grep telling me I have an invalid option when searching for "+foo"?
       ack-grep treats command line options beginning with "+" or "-" as options; if you would
       like to search for these, you may prefix your search term with "--" or use the "--match"
       option.  (However, don't forget that "+" is a regular expression metacharacter!)

   Why does "ack '.{40000,}'" fail?  Isn't that a valid regex?
       The Perl language limits the repetition quanitifier to 32K.  You can search for ".{32767}"
       but not ".{32768}".


       Ack can load its configuration from many sources.  This list specifies the sources Ack
       looks for configuration; each one that is found is loaded in the order specified here, and
       each one overrides options set in any of the sources preceding it.  (For example, if I set
       --sort-files in my user ackrc, and --nosort-files on the command line, the command line
       takes precedence)

       •   Defaults are loaded from App::Ack::ConfigDefaults.  This can be omitted using

       •   Global ackrc

           Options are then loaded from the global ackrc.  This is located at "/etc/ackrc" on
           Unix-like systems, and "C:\Documents and Settings\All Users\Application Data\ackrc" on
           Windows.  This can be omitted using "--noenv".

       •   User ackrc

           Options are then loaded from the user's ackrc.  This is located at "$HOME/.ackrc" on
           Unix-like systems, and "C:\Documents and Settings\$USER\Application Data\ackrc".  If a
           different ackrc is desired, it may be overridden with the $ACKRC environment variable.
           This can be omitted using "--noenv".

       •   Project ackrc

           Options are then loaded from the project ackrc.  The project ackrc is the first ackrc
           file with the name ".ackrc" or "_ackrc", first searching in the current directory,
           then the parent directory, then the grandparent directory, etc.  This can be omitted
           using "--noenv".

       •   --ackrc

           The "--ackrc" option may be included on the command line to specify an ackrc file that
           can override all others.  It is consulted even if "--noenv" is present.

       •   ACK_OPTIONS

           Options are then loaded from the environment variable "ACK_OPTIONS".  This can be
           omitted using "--noenv".

       •   Command line

           Options are then loaded from the command line.


       A lot of changes were made for ack-grep 2; here is a list of them.

       •   When no selectors are specified, ack-grep 1.x only searches through files that it can
           map to a file type.  ack-grep 2.x, by contrast, will search through every regular,
           non-binary file that is not explicitly ignored via --ignore-file or --ignore-dir.
           This is similar to the behavior of the -a/--all option in ack-grep 1.x.

       •   A more flexible filter system has been added, so that more powerful file types may be
           created by the user.  For details, please consult "Defining your own types".

       •   ack-grep now loads multiple ackrc files; see "ACKRC LOCATION SEMANTICS" for details.

       •   ack-grep's default filter definitions aren't special; you may tell ack-grep to
           completely disregard them if you don't like them.

       •   Because of the change in default search behavior, the -a/--all and -u/--unrestricted
           options have been removed.  In addition, the -k/--known-types option was added to
           cause ack-grep to behave with the default search behavior of ack-grep 1.x.

       •   The -G option has been removed.  Two regular expressions on the command line was
           considered too confusing; to simulate -G's functionality, you may use the new -x
           option to pipe filenames from one invocation of ack-grep into another.

       •   The --binary option has been removed.

       •   The --skipped option has been removed.

       •   The --text option has been removed.

       •   The --invert-file-match option has been removed.  Instead, you may use -v with -g.

       •   The options that modify the regular expression's behavior (-i, -w, -Q, and -v) may now
           be used with -g.

   ADDED OPTIONS--files-from was added so that a user may submit a list of filenames as a list of
           files to search.

       •   -x was added to tell ack-grep to accept a list of filenames via standard input; this
           list is the list of filenames that will be used for the search.

       •   -s was added to tell ack-grep to suppress error messages about non-existent or
           unreadable files.

       •   --ignore-directory and --noignore-directory were added as aliases for --ignore-dir and
           --noignore-dir respectively.

       •   --ignore-file was added so that users may specify patterns of files to ignore (ex.

       •   --dump was added to allow users to easily find out which options are set where.

       •   --create-ackrc was added so that users may create custom ackrc files based on the
           default settings loaded by ack-grep, and so that users may easily view those defaults.

       •   --type-del was added to selectively remove file type definitions.

       •   --ignore-ack-defaults was added so that users may ignore ack-grep's default options in
           favor of their own.

       •   --bar was added so ack-grep users may consult Admiral Ackbar.
