If the fix >has already been posted, could someone please mail me the diffs? Thanks. The message is correct. On our system it is a little clearer: grep: RE error 49: [ ] imbalance. The "[" character is used to introduce a range specification, as in "[a-z]" to match a single character in the range of "a" to "z". To search for a literal '[' character you should escape it with a backslash, as in: grep '\[' file Hope this helps. -- John Sambrook Work: (206) 545-2018 University of Washington WD-12 Home: (206) 487-0180 Seattle, Washington 98195 UUCP: uw-beaver!uw-nsr!john
