I was afraid of that. Thank you for the confirmation

Sure. Sorry I wasn't clear enough the first time.
I have
path/file
path/RCS/file,v
and I'd like to autocheck in path/file if it's been modified
To do this, I did:
TORCSFILES=path1/file1 path2/file2 file3
TORCS=$(shell echo '$(TORCSFILES)' | sed -e 's/\/\([^/]*\) /\/RCS\/\1 /g'
-e 's/\<\([^/]*\) /RCS\/\1 /g' -e 's/RCS\/RCS/RCS/g' -e 's/ */,v /'g)
Which gives me:
TORCS=path1/RCS/file1,v path2/RCS/file2,v RCS/file3,v # (path is optional)
I'd like to have something like this:
rcs: $(TORCS)
RCS/%,v: %
ci -l $<
touch $@
This works fine, but it stops working when I have path/RCS/file,v instead of
RCS/file,v
If I had real regexes, I could do:
\(.*\)RCS/\([^/]\),v: \1\2
Does that make more sense? :-)
Thanks,
Marc
