[Sussex] Bash string substitution

[Ronan Chilvers]

Sorry to reply to my own post but just cracked it:

for FIL in "Catalogue labels Size "$1/.*; do
	PAT="s/A/BC/g"
	NEW=$(basename "$FIL" | sed "$PAT")
	echo $NEW
done

I was using single rather than double quotes on my sed expression which
is where the problem lay...

Cheers

Ronan
