       cloc - Count, and compute differences of, lines of source code and


         cloc [options] <FILE|DIR> ...


       Count, or compute differences of, physical lines of source code in the
       given files (may be archives such as compressed tarballs or zip files)
       and/or recursively below the given directories.  It is written entirely
       in Perl, using only modules from the standard distribution.


   Input Options
       To count standard input, use the special filename -.

           This option is only needed if cloc is unable to figure out how to
           extract the contents of the input file(s) by itself. Use CMD to
           extract binary archive files (e.g.: .tar.gz, .zip, .Z). Use the
           literal '>FILE<' as a stand-in for the actual file(s) to be
           extracted. For example, to count lines of code in the input files
           gcc-4.2.tar.gz perl-5.8.8.tar.gz on Unix use:

               --extract-with='gzip -dc >FILE< | tar xf -

           or, if you have GNU tar:

               --extract-with='tar zxf >FILE<'

           and on Windows, use, for example:

               --extract-with="\"c:\Program Files\WinZip\WinZip32.exe\" -e -o >FILE<

           Take the list of file and/or directory names to process from FILE
           which has one file/directory name per line. See also

           Check binary files to see if they contain Unicode expanded ASCII
           text.  This causes performance to drop noticably.

   Processing Options
           Count .in files (as processed by GNU autoconf) of recognized

           Report results for every source file encountered.

           Report results for every source file encountered in addition to
           reporting by language.

       --diff SET1 SET2
           Compute differences in code and comments between source file(s) of
           SET1 and SET2.  The inputs may be pairs of files, directories, or
           archives.  Use --diff-alignment to generate a list showing which
           file pairs where compared.  See also --ignore-case,

       --diff-timeout N
           Ignore files which take more than N seconds to process.  Default is
           10 seconds.  (Large files with many repeated lines can cause
           Algorithm::Diff::sdiff() to take hours.)

           [Unix only] Follow symbolic links to directories (sym links to
           files are always followed).

           Process all files that have a EXT extension with the counter for
           language LANG. For example, to count all .f files with the Fortran
           90 counter (which expects files to end with .f90) instead of the
           default Fortran 77 counter, use:

                   --force-lang="Fortran 90",f

           If EXT is omitted, every file will be counted with the LANG
           counter.  This option can be specified multiple times (but that is
           only useful when EXT is given each time). See also --script-lang,

           Load language processing filters from FILE, then use these filters
           instead of the built-in filters.  Note:  languages which map to the
           same file extension (for example: MATLAB/Objective C/MUMPS;
           Pascal/PHP; Lisp/OpenCL) will be ignored as these require
           additional processing that is not expressed in language definition
           files.  Use --read-lang-def to define new language filters without
           replacing built-in filters (see also --write-lang-def).

           Ignore horizontal white space when comparing files with --diff.
           See also --ignore-case.

           Ignore changes in case; consider upper- and lowercase letters
           equivalent when comparing files with --diff.  See also

           Count files without extensions using the LANG counter.  This option
           overrides internal logic for files without extensions (where such
           files are checked against known scripting languages by examining
           the first line for "#!").  See also --force-lang, --script-lang.

           Skip files larger than "MB" megabytes when traversing directories.
           By default, "MB"=100.  cloc's memory requirement is roughly twenty
           times larger than the largest file so running with files larger
           than 100 MB on a computer with less than 2 GB of memory will cause
           problems.  Note:  this check does not apply to files explicitly
           passed as command line arguments.

           Process binary files in addition to text files. This is usually a
           bad idea and should only be attempted with text files that have
           embedded binary data.

           Load new language processing filters from FILE and merge them with
           those already known to cloc.  If FILE defines a language cloc
           already knows about, cloc's definition will take precedence.  Use
           --force-lang-def to over-ride cloc's definitions.  (see also

           Process all files that invoke "S" as a "#!" scripting language with
           the counter for language LANG. For example, files that begin with
           "#!/usr/local/bin/perl5.8.8" will be counted with the Perl counter
           by using


           The language name is case insensitive but the name of the script
           language executable, "S", must have the right case. This option can
           be specified multiple times. See also --force-lang.

           Use DIR as the scratch directory instead of letting File::Temp
           chose the location. Files written to this location are not removed
           at the end of the run (as they are with File::Temp).

           Skip the file uniqueness check. This will give a performance boost
           at the expense of counting files with identical contents multiple
           times (if such duplicates exist).

           Count lines streamed via STDIN as if they came from a file named

           For each file processed, write to the current directory a version
           of the file which has blank lines and comments removed. The name of
           each stripped file is the original file name with ".EXT" appended
           to it.  It is written to the current directory unless
           --original-dir is on.

           Write the stripped files the same directory as the original files.
           Only effective in combination with --strip-comments.

           Input arguments are report files previously created with the
           --report-file option. Makes a cumulative set of results containing
           the sum of data from the individual report files.

           Over-ride the operating system detection logic and run in UNIX
           mode.  See also --windows, --show-os.

           Over-ride the operating system detection logic and run in Microsoft
           Windows mode.  See also --unix, --show-os.

   Filter Options
       --exclude-dir=<dir[,<dir> ...]>
           Exclude the given comma separated directories from being scanned.
           For example:


           will skip all files that match "/.cache/" or "/test/" as part of
           their path. Directories named ".bzr", ".cvs", ".hg", ".git", ".hg",
           and ".svn" are always excluded.

       --exclude-ext=EXT1[,EXT2 ...]
           Do not count files having the given file name extensions.

       --exclude-lang=<L1[,<L2> ...]>
           Exclude the given comma separated languages from being counted.

           Ignore files whose names appear in FILE. FILE should have one entry
           per line. Relative path names will be resolved starting from the
           directory where cloc is invoked. See also --list-file.

           Only count files in directories matching the Perl regex.  For


           only counts files in directory paths containing "/src/" or

           Count all files except in directories matching the Perl regex.

           Only count files whose basenames match the Perl regex. For example
           this only counts files at start with Widget or widget:


           Count all files except those whose basenames match the Perl regex.

           Ignore files that end with the given Perl regular expression.  For
           example, if given
             --skip-archive='(zip|tar(\.(gz|Z|bz2|xz|7z))?)'  the code will
           skip files that end with .zip, .tar, .tar.gz, .tar.Z, .tar.bz2,
           .tar.xz, and .tar.7z.

           On Windows, ignore hidden files.

   Debug Options
           Save names of categorized files to FILE.

           Save names of processed source files to FILE.

           Write to FILE a list of files and file pairs showing which files
           were added, removed, and/or compared during a run with --diff.
           This switch forces the --diff mode on.

           Print this usage information and exit.

           Save names of every file found to FILE.

           Save names of ignored files and the reason they were ignored to

           Print to STDOUT processed source code before and after each filter
           is applied.

           Print information about all known (or just the given) file
           extensions and exit.

           Print information about all known (or just the given) languages and

           Print the value of the operating system mode and exit.  See also
           --unix, --windows.

           Turn on verbose with optional numeric value.

           Print the version of this program and exit.

           Writes to FILE the language processing filters then exits. Useful
           as a first step to creating custom language definitions. See also
           --force-lang-def, --read-lang-def.

   Output Options
       --3 Print third-generation language output.  (This option can cause
           report summation to fail if some reports were produced with this
           option while others were produced without it.)

           Show progress update after every N files are processed (default
           N=100). Set N to 0 to suppress progress output; useful when
           redirecting output to STDOUT.

           Suppress all information messages except for the final report.

           Write the results to FILE instead of standard output.

           Synonym for --report-file=FILE.

           Write the results as comma separated values.

           Use the character C as the delimiter for comma separated files
           instead of ,.  This switch forces --csv to be on.

           Write results as SQL CREATE and INSERT statements which can be read
           by a database program such as SQLite. If FILE is -, output is sent
           to STDOUT.

           Use <name> as the project identifier for the current run. Only
           valid with the --sql option.

           Append SQL insert statements to the file specified by --sql and do
           not generate table creation option.

           For plain text reports, show the SUM: output line even if only one
           input file is processed.

           Write the results in XML.

           Reference FILE as an XSL stylesheet within the XML output. If FILE
           is not given, writes a default stylesheet, cloc.xsl. This switch
           forces --xml to be on.

           Write the results in YAML.


       Count the lines of code in the Perl 5.10.0 compressed tar file on a
       UNIX-like operating system:

         cloc perl-5.10.0.tar.gz

       Count the changes in files, code, and comments between Python releases
       2.6.6 and 2.7:

         cloc --diff  Python-2.7.tar.bz2

       To see how cloc aligns files for comparison between two code bases, use
       the --diff-alignment=FILE option.  Here the alignment information is
       written to "align.txt":

         cloc --diff-aligment=align.txt gcc-4.4.0.tar.bz2  gcc-4.5.0.tar.bz2

       Print the recognized languages

         cloc --show-lang

       Remove comments from "foo.c" and save the result in ""

         cloc --strip-comments=nc foo.c
