[sclug] Escaping slashes in bash

[Peter Brewer]

Dear SCLUG

Having some problems with escaping "/" in Bash.  We want to run perl 
-pie in a bash script but have had to first put the substitution string 
into a variable otherwise it doesn't get created properly.  This works 
fine when there are no "/" in the substitution string but how do we get 
it to work if there IS a "/"????

e.g:
WORKDIR="/tmp"
LOCALITIESFILE="foobar.txt"
CMD="s/\[LOCALITIESFILE]/${WORKDIR}\/${LOCALITIESFILE}/g"
`perl -p -i -e ${CMD} ${FILENAME1}`

Many thanks once again for your combined help!

Cheers

Pete
