NAME

       dlocate - program to view debian package information

SYNOPSIS

       dlocate [OPTIONS] [command] [ package...  | PATTERN...]

DESCRIPTION

       dlocate is a fast alternative to dpkg for queries like `dpkg -L' and `dpkg -S'

COMMANDS

       (none) List all records where either the package name or the filename matches PATTERN.

              Note  that  dlocate uses GNU grep, so normal regexp metacharacters need to be taken
              into account or avoided by using the '-F' (Fixed String) grep option.

              For example, to search for `/usr/bin/[', you might try:  dlocate  '/usr/bin/\['  or
              dlocate -F '/usr/bin/['

       -S     List all records where only the filename matches PATTERN.

              Note  that  dlocate uses GNU grep, so normal regexp metacharacters need to be taken
              into account.  Fixed String searches are incompatible with -S.

              For example, to search for `/usr/bin/[', you need to type:

              dlocate  '/usr/bin/\['

       -l     Regexp-enhanced emulation of `dpkg -l'.  Shows all packages which match package.

              Internally this uses grep on a file containing the reformatted output of 'dpkg  -l'
              (four  fields  separated  by  tabs;  status, package-name, installed version, short
              description) so it will return packages whose version or short description matches,
              too.

              Various flavours of regular expression are supported. For example, Extended Regexp:

              dlocate -l '^..[[:space:]]libc6'

              or Perl Regexp:

              dlocate -P -l '^..\slibc6'

              Both of these will list all the packages whose names start with `libc6'.

              Note  that  because  of  the  difference  between  regular  expressions  and dpkg's
              shell-style pattern matching, the output from dlocate -l is occasionally  different
              to the output from dpkg -l.

              This  is  not  a  bug, regular expressions are far more flexible than shell pattern
              matching. This is the way dlocate is supposed to  run,  but  it  may  require  some
              knowledge of regular expressions to get the output you want.

       -k     List package names of installed kernels and all related packages

       -K     Detailed list of installed kernels and all related packages

       -L     List all files in package.

       -s     Print status of package.

       --ls   `ls -ldF' of all files in package.

       --lsconf
              `ls -ldF' of conffiles in package.

       --conf List conffiles in package.

       --du   `du -sck' of all files in package.

       --md5sum
              List md5sums (if any) of package.

       --md5check
              Check md5sums (if any) of package.

       --man  List man pages (if any) in package.

       --lsman
              List full path/filenames of man pages (if any) in package.

       --lsbin
              List full path/filenames of executable files (if any) in package.

       --lsdir
              List only the directories in package.

OPTIONS

       --filename-only
              Only output file names when searching for files

       --package-only
              Only output package names when searching for files

       -w, --word-regexp
              Select only those lines containing matches that form whole words.  The test is that
              the matching substring must either be at the beginning of the line, or preceded  by
              a  non-word  constituent  character. Similarly, it must be either at the end of the
              line or followed by a non-word constituent character.  Word-constituent  characters
              are letters, digits, and the underscore.

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

       -E, --extended-regexp
              Interpret PATTERN as an extended regular expression.  This is the default.

       -F, --fixed-strings
              Interpret  PATTERN  as a list of fixed strings, separated by newlines, any of which
              is to be matched.

       -G, --basic-regexp
              Interpret PATTERN as a basic regular expression.

       -P, --perl-regexp
              Interpret PATTERN as a Perl regular expression.  This is considered  to  be  highly
              experimental within GNU grep and may warn of unimplemented features.

       -h, --help
              Display help message and exit.

       -V, --version
              Display dlocate's version number and exit.

       -v, --verbose, --debug
              Produce verbose debugging output

       -c, --columns[=columns]
              Set  COLUMN width to override the dlocate default of using the entire terminal line
              width.  Any value for columns less than 80 will be increaed to 80.

       -C, --colour, --color
              Colourise -l or -s output (requires supercat to be installed)

FILES

       /etc/default/dlocate
              Configuration  file  with  default  options.  Currently  the  only  option  is   to
              enable/disable gzip compression of /var/lib/dlocate/dlocatedb.

       /var/lib/dlocate/dlocatedb
              Plain text listing of all files belonging to all packages (optionally compressed)

       /var/lib/dlocate/dpkg-list

NOTES

       dlocate does not update its databases (see  FILES  section)  automatically  after  new  or
       upgraded packages have been installed with dpkg or apt-get etc.
       A  daily cron job is run to perform the update.  Or the root user can run update-dlocatedb
       at any time to force an update.

ENVIRONMENT VARIABLES

       COLUMNS
              Sets the number of columns dlocate  should  use  when  displaying  formatted  text.
              Currently only used by -l. Values lower than 80 are increased to 80.
