Is there a utility to canonify strings in the shell for testing?

In a shell module of mine I use something in the lines of:

CESSID=$( echo $ESSID | tr -c "a-zA-Z0-9_" "_" | sed -e 's/_*$//' )

The sed line removes trailing underscores -- I always got one because of
a newline character in $ESSID. You may want to remove just one, or none,
or "chomp" your counterpart of ESSID beforehand.

Ciao!

Use echo -n.

I think Perl is a *little* bit nicer for this because of the \W
(non-word) character class:

perl -p -e's/\W/_/g'
