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.

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

NOT

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

For that use Shell::Command.

Filenames with * and ? will be glob expanded.

  • cat
    1. cat file ...

    Concatenates all files mentioned on command line to STDOUT.

  • eqtime
    1. eqtime source destination

    Sets modified time of destination to that of source.

  • rm_rf
    1. rm_rf files or directories ...

    Removes files and directories - recursively (even if readonly)

  • rm_f
    1. rm_f file ...

    Removes files (even if readonly)

  • touch
    1. touch file ...

  • mv
    1. mv source_file destination_file
    2. 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
    1. cp source_file destination_file
    2. 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.

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

  • mkpath

    Creates directories, including any parent directories.

  • test_f
    1. test_f file
