Re^3: Permissions for a separately installed perl

Ok, in that shell, what does

perl -e 'print "$]\n";'
[download]

yield?

The shell hashes paths to commands, and if you add a command to a path previous in $PATH to the already hashed one, your may not see the changes:

qwurx [shmem] ~> touch blorflydick
qwurx [shmem] ~> rm blorflydick
qwurx [shmem] ~> mkdir bin
qwurx [shmem] ~> PATH=$HOME/bin:$PATH
qwurx [shmem] ~> which rm
/bin/rm
qwurx [shmem] ~> echo '#!/bin/sh' > bin/rm
qwurx [shmem] ~> echo 'echo no rm damnit' >> bin/rm
qwurx [shmem] ~> chmod a+x bin/rm
qwurx [shmem] ~> which rm
~/bin/rm
qwurx [shmem] ~> rm blorflydick
rm: cannot remove `bloflydick': No such file or directory
qwurx [shmem] ~>
[download]

A new shell will see the changes, however:

qwurx [shmem] ~> echo $SHLVL
4
qwurx [shmem] ~> bash
qwurx [shmem] ~> echo $SHLVL
5
qwurx [shmem] ~> rm blorflydick
no rm damnit
qwurx [shmem] ~>
[download]

A new shell will see the changes or `$ hash -r` [download] to make `bash` forget its cached bindings.	[reply] [d/l] [select]
