# NAME

# 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
