As long as you can print out the file names using some filter arrangement as demonstrated by the various mechanisms above, you can use awk or similar to create the command 'chmod +rwx afile.name' and then pipe the command to a shell.
The joy of linux is that you try and break everything down into little steps, and then put them together to create what you need:)
...as does mine, except, perhaps I ought to give an example:
find / -gid xyz | awk '{print "chmod group.group",$1}' | /bin/sh
The great thing about the above is that it is very flexible. You can create a list of files that includes only text files with the string .txt by adding a grep pipe:
find / -gid xyz | grep ".txt" | awk '{print "chmod group.group",$1}' | /bin/sh
etc
Using the awk command you can carry out any action you wish on the files by building the necesary command string before piping it to a shell.
Top tip (because I like top tips!) is to test the command line without the | /bin/sh first to check that the commands being produced are the commands that you want actioning. Only then, send them to the shell.
I agree that ahoffman was the first person to come up with a solution....I just think my approach is better;)
OK - ahoffmann wins on a more succint way of doing that one as well ;) - I was trying to break the problem down into nice simple steps......./me goes and looks for the URL for obfuscated C code contest.....and finds it:)
