. - install perl-<version-number>
- install <version-number>

- list
-
List the installed versions of perl.
- use [perl-<version>]
- use [<version>]
-
Switch to the given version of perl only in the current shell. This will not effect newly opened shells.
You can use as
perl-version
the special keywordsystem
to stop using any perlbrew-based perl.Without a parameter, shows the version of perl currently in use.
- switch [perl-<version>]
- switch [<version>]
-
Switch to the given version, and makes it the default for this and all future terminal sessions.
Without a parameter, shows the version of perl currently selected.
- alias [-f] create <name> <alias>
-
Create an alias for the installation named <name>.
- alias [-f] rename <old_alias> <new_alias>
-
Rename the alias to a new name.
- alias delete <alias>

Disable perlbrew. Use
switch
command to re-enable it. - exec command
-
Execute command for all perls.
For example, run a Hello program:
perlbrew exec perl -e 'print "Hello from $]\n"'
Depending on your actual installations, the output might look like this:
perl-5.12.2 ========== Hello word from perl-5.012002 perl-5.12.3 ========== Hello word from perl-5.012003 perl-5.13.10 ========== Hello word from perl-5.013010 perl-5.14.0 ========== Hello word from perl-5.014000
- env [perl-version]
-
Low-level command. Use this command to see the list of environment variables that are set by
perlbrew
itself for shell integration.The output is something similar to this (if your shell is bash):
export PERLBREW_ROOT=/Users/gugod/perl5/perlbrew export PERLBREW_VERSION=0.13 export PERLBREW_PATH=/Users/gugod/perl5/perlbrew/bin:/Users/gugod/perl5/perlbrew/perls/current/bin export PERLBREW_PERL=perl-5.12.3
You can also ask for the proper variables for a specific perl version.
- symlink_executables <perl-version>
-
Low-level command. Use this command to create the
perl
executable symbolic link to , say,perl5.13.6
. This is only useful for development version of perls.You don't need to do this unless you have been 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/perl -> ${PERLBREW_ROOT}/perls/perl-5.13.6/bin/perl5.13.6
