perlbrew - Perl Environment manager.


    perlbrew <command> [options] [arguments]

    Commonly used commands:
        init           Initialize perlbrew environment.
        install        Install perl
        list           List installed perls
        use            Use the specified perl in current shell
        switch         Permanently use the specified perl as default
        mirror         Pick a preffered mirror site
        off            Permanently turn off perlbrew
        version        Display version
        help           Read more detail instructions

        perlbrew install perl-5.12.2
        perlbrew install perl-5.13.6

        perlbrew list

        perlbrew use perl-5.13.6
        perlbrew switch perl-5.12.2



Run this once to setup the perlbrew directory ready for installing perls into. Run it again if you decide to change PERLBREW_ROOT.


Run this if you want to choose a specific CPAN mirror to install the perls from. It will display a list of mirrors for you to pick from. Hit 'q' to cancel the selection.

install perl-<version>

Build and install the given version of perl.

install /path/to/perl/git/checkout/dir

Build and install from the given git checkout dir.


List the installed versions of perl.

use perl-<version>

Notice: this only works in bash and zsh.

Switch to the given version of perl only in the current shell. This will not effect newly opened shells.

switch perl-<version>

Switch to the given version. You may need to run 'rehash' (or 'hash -r') after this command.


Show the version of perbrew.


Disable perlbrew. Use switch command to re-enable it.


Low-level command. Use this command to see the list of environment variables that are set by perlbrew itself for bash integration.

The output is something similar to this:

    export PERLBREW_ROOT=/Users/gugod/perl5/perlbrew
    export PERLBREW_VERSION=0.13
    export PERLBREW_PATH=/Users/gugod/perl5/perlbrew/bin

Low-level command. Use this command to create the perl executable symbolic link to perl5.13.6.

You don't need to do this unless you were using old perlbrew to install perls. The installation layout is changed since version 0.11.

If you just upgraded perlbrew and found perlbrew switch failed to work after you switch to a development release of perl, say, perl-5.13.6, run this command:

    perlbrew symlink_executables perl-5.13.6

This essentially creates this symlink:

   -> ${PERLBREW_ROOT}/perls/perl-5.13.6/bin/perl5.13.6

Install the cpanm standalone executable in $PERLBREW_ROOT/bin.


-h| --help

prints this help.

-f| --force

Force installation of a perl.

-n| --notest

Skip the test suite

-q| --quiet

Log output to a log file rather than STDOUT. This is the default. The log file is saved in $ROOT/build.log

-v| --verbose

Log output to STDOUT rather than a logfile.


Install a given perl under an alias.

    perlbrew install perl-5.6.2 --as legacy-perl
-D, -U, -A

pass through switches to the perl Configure script.

    perlbrew install perl-5.10.1 -D usemymalloc -U uselargefiles



By default, perlbrew builds and installs perls into $ENV{HOME}/perl5/perlbrew directory. To use a different directory, set this environment variable in your bashrc to the directory before running perlbrew.
