Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. Note that this is not identical to the -executable predicate in GNU find. This answer attempts to provide an overview of the existing answers and to discuss their subtleties and relative merits as well as to provide background information , especially with respect to portability. Note that in either scenario it may make sense to use find -L Note that the simplest file-centric case - looking for executables with the executable permissions bit set for ALL three security principals user, group, other - will typically , but not necessarily yield the same results as the user-centric scenario - and it's important to understand the difference.

It's not something you have to add, like bash or tcsh, and it's usually available on any modern Unix you are likely to work on. Personally, I prefer Bash very similar in features to ksh , but you may not have it easily available. If that's the case, ksh is better than sh.
