And they were right, it works just great if you have a space after the if. My thanks to David C Lawrence <uunet!pawl.rpi.edu!tale> and Bradley White <uunet!mtxinu.com!bww> for pointing this out. Thus ends the saga. If any wizards out there want a copy of my un-news script, email me (it takes news articles which have been saved away and un-shars or un-uudecodes them into another location, and handles both multiple-part articles and single articles. It does not as of yet handle patches, and probably never will). ---------- Rusty Carruth UUCP:{uunet,boulder}!cadnetix!rusty DOMAIN: rusty@cadnetix.com Daisy/Cadnetix Corp.

I never had that problem and I would assume that something else could be wrong in the shell script that you wrote. My suggestion would be to "debug" the script using -xv flags; i.e. the first line of the program would be #!/bin/csh -xv (4.3 BSD manual discusses this flags.) Also I think that in the example above it might be appropriate to use ' ~= ' for pattern matching instead of ' == ' which is used in expressions. Chap-7 in the text-book about C-shell discusses this.
