ExtUtils::Command(3pm)                Perl Programmers Reference Guide                ExtUtils::Command(3pm)



NAME
       ExtUtils::Command - utilities to replace common UNIX commands in Makefiles etc.

SYNOPSIS
         perl -MExtUtils::Command -e cat files... > destination
         perl -MExtUtils::Command -e mv source... destination
         perl -MExtUtils::Command -e cp source... destination
         perl -MExtUtils::Command -e touch files...
         perl -MExtUtils::Command -e rm_f files...
         perl -MExtUtils::Command -e rm_rf directories...
         perl -MExtUtils::Command -e mkpath directories...
         perl -MExtUtils::Command -e eqtime source destination
         perl -MExtUtils::Command -e test_f file
         perl -MExtUtils::Command -e test_d directory
         perl -MExtUtils::Command -e chmod mode files...
         ...

DESCRIPTION
       The module is used to replace common UNIX commands.  In all cases the functions work from @ARGV
       rather than taking arguments.  This makes them easier to deal with in Makefiles.  Call them like
       this:

         perl -MExtUtils::Command -e some_command some files to work on

       and NOT like this:

         perl -MExtUtils::Command -e 'some_command qw(some files to work on)'

       For that use Shell::Command.

       Filenames with * and ? will be glob expanded.

       FUNCTIONS


       cat
               cat file ...

           Concatenates all files mentioned on command line to STDOUT.

       eqtime
               eqtime source destination

           Sets modified time of destination to that of source.

       rm_rf
               rm_rf files or directories ...

           Removes files and directories - recursively (even if readonly)

       rm_f
               rm_f file ...

           Removes files (even if readonly)

       touch
               touch file ...

           Makes files exist, with current timestamp

       mv
               mv source_file destination_file
               mv source_file source_file destination_dir

           Moves source to destination.  Multiple sources are allowed if destination is an existing
           directory.

           Returns true if all moves succeeded, false otherwise.

       cp
               cp source_file destination_file
               cp source_file source_file destination_dir

           Copies sources to the destination.  Multiple sources are allowed if destination is an existing
           directory.

           Returns true if all copies succeeded, false otherwise.

       chmod
               chmod mode files ...

           Sets UNIX like permissions 'mode' on all the files.  e.g. 0666

       mkpath
               mkpath directory ...

           Creates directories, including any parent directories.

       test_f
               test_f file

           Tests if a file exists.  Exits with 0 if it does, 1 if it does not (ie.  shell's idea of true and
           false).

       test_d
               test_d directory

           Tests if a directory exists.  Exits with 0 if it does, 1 if it does not (ie. shell's idea of true
           and false).

       dos2unix
               dos2unix files or dirs ...

           Converts DOS and OS/2 linefeeds to Unix style recursively.

SEE ALSO
       Shell::Command which is these same functions but take arguments normally.
