I've got a setup where I need to use 'find' to find 0 or more files in a certain directory, however, 'find' always produces an error when there are no files that match a certain check. Is it possible to run 'find' while having it omit errors when no files match the pattern?
Like @grawity said find isn't expected to report these errors. Anyway if you want to suppress error output redirect stderr to /dev/null:
find . HERE_YOUR_FIND_PARAMS 2&> /dev/null
One typical case in which find write to stderr happens when there is a directory in your find searching sub-path that hasn't the permission to be opened.
