Perlswitcher - Switch between system Perl + local::lib and user Perl

This is a cheap script to switch between system Perl with local::lib and user Perl (installed by Perlbrew) without local::lib. Environment variables are set so that cpanm always knows where to install packages (local::lib or user Perl).

Nothing will be installed system-wide, no root permissions are required. Installing Perl packages manually in the system Perl as root might create chaos and mess up the system. Using this script, packages can be installed locally without ever having to become root and if some packages are causing trouble in a user Perl, that Perl installation can simply be deleted.

INSTALLATION

Install Perlbrew (http://perlbrew.pl/).

$ mkdir ~/perl5/userperls

Copy this script to ~/perl5/userperls/bashrc

$ echo '. ~/perl5/userperls/bashrc' >>~/.bashrc

Add symlinks for directories to be prepended to $PATH. Their names must begin with "path-".

$ cd ~/perl5/userperls/
$ ln -s ~/perl5/bin path-bin
$ ln -s ~/perl5/perlbrew/bin path-perlbrew-bin

UNINSTALLATION

Remove this script from your "~/.bashrc".

Delete the "userperls" directory.

USAGE

Switch to a user Perl installed by Perlbrew:

$ perlswitch perl-5.18.4

Find out if user Perl or system Perl is currently being used:

$ perlinfo

Switch back to system Perl:

$ perlswitch

Use perldoc to see some examples:

$ perldoc ~/perl5/userperls/bashrc
