ExtUtils::Command(3)

🌸 NAME 🌸

ExtUtils::Command(3) — straight outta the User Contributed Perl Documentation section — is literally your little toolbox of 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 ...

👀 SEE ALSO 👀

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