## PERL_DEFAULT is used by various utilities that need to have ## access to some version of Perl while we are in the middle of ## swapping Perl versions. See addpath and delpath for example. export PERL_DEFAULT=/usr/bin/perl ## This setting tells swap_perl that there is no current version to ## swap out of before swapping in the requested version. export PERL_CURRENT_VERSION='initial' ## Do it swap_perl 5.6.1
Example 6: Setting the default Perl environment in perl.sh.
