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.
