Completely untested, but the usual thing with find(1) is down to the way it evaluates its arguments from left to right in a lazy fashion. So, if it has enough to know it is going to generate a true or false result after '-type d ! -uid num', it won't then go on to evaluate the rest of the line, meaning it will never see the effects of '-prune'. If you want to have exceptions, it is generally better to put them earlier in the command line: find /path/to/dir \( -type d ! -name dirname -prune \) -type d ! -uid num= Or you could use '-path' to match any path containing 'dirname' without the bracketed subexpression: find /path/to/dir -type d ! -path 'dirname*' ! -uid Cheers, Matthew --=20 Dr Matthew J Seaman MA, D.Phil.
