Apologies if this question has popped up in the past but...
I was trying to rename a group of files from 'st.*' to '*'
e.g.
st.fred.dat => fred.dat
st.jim.c => jim.c
st.nick => nick
I noticed that there was (according to the csh manual) an operator :s/l/r/
which was supposed to substitute 'r' for 'l' within the filename.
So, I tried (amongst other things):
foreach i (st.*)
mv $i $i:s/st.//
end
This replies with a message 'Variable syntax'
Could some kind soul out there please point out to me what I am doing wrong.
I could achieve the correct result with sed, but would like to use this
apparently nice feature (bug :-) in csh.
Thanks.

The :s modifier is a *history* modifier. The only variable modifiers are h, t, r, q, x: head, tail, root, quote, and quote-except-at-spaces. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7690) UUCP: seismo!mimsy!chris ARPA/CSNet: chris@mimsy.umd.edu
