Subject: noclobber shell option prevents switch
The bash shell option 'noclobber' (which prevents accidental overwriting of existing files when using shell redirection) prevents Perlbrew from being able to switch perls. This seems to be due to __perlbrew_reinit() which creates $HOME/.perlbrew/init anew using shell redirection. This can be fixed by writing the redirection as (patch attached): echo '# DO NOT EDIT THIS FILE' >| $HOME/.perlbrew/init When the noclobber shell option is not set, the semantics will be the same.

Awesome catch! This might be the cause of some many "perlbrew switch is not working" I've seen from time to time. Thanks a lot!
