Switching to the system Perl using perlbrew

First, some background.

perlbrew is a tool to assist with the installation of Perl into a non-standard directory (usually under your home directory).

It also helps you control which Perl installation is used when executing perl in an interactive shell. Switching between installations is done using perlbrew use and perlbrew switch. perlbrew use only affects the current shell, while perlbrew switch is more permanent.

$ perl -V:version             |  $ perl -V:version
version='5.20.0';             |  version='5.20.0';
                              |
$ perlbrew use 5.18.2t        |  $ perlbrew switch 5.18.2t
                              |
$ perl -V:version             |  $ perl -V:version
version='5.18.2';             |  version='5.18.2';
                              |
$ bash -ic 'perl -V:version'  |  $ bash -ic 'perl -V:version'
version='5.20.0';             |  version='5.18.2';

perlbrew off is used to revert to using the system Perl, but it's temporary like perlbrew use. Is there a way to revert to the system Perl with the permanency of perlbrew switch?

Solution

  • You can use the following command
