Suppose you have a stow directory all set up and ready to go: /usr/local/stow/perl contains the Perl installation, /usr/local/stow/stow contains Stow itself, and perhaps you have other packages waiting to be stowed. You’d like to be able to do this:
cd /usr/local/stow stow -vv *
but stow is not yet in your PATH. Nor can you do this:
cd /usr/local/stow stow/bin/stow -vv *
because the ‘#!’ line at the beginning of stow tries to
locate Perl (usually in /usr/local/bin/perl), and that won’t be
found. The solution you must use is:
cd /usr/local/stow perl/bin/perl stow/bin/stow -vv *
