Permission checks in shell script

A reader of my new book Wicked Cool Shell Scripts pointed out that the capability of testing a file permission with find using the '+' notation is GNU-specific.

Dave's Answer:

Specifically, in script #49, findsuid, the line:

for match in $(find /bin /usr/bin -type f -perm +4000 -print)

might need to be tweaked on some Unix versions to be -perm -4000, which will produce the same basic results.

That would look like this:

for match in $(find /bin /usr/bin -type f -perm -4000 -print)

Hope that helps clarify things!
