- <tt>-e FILE</tt> returns true if \c FILE exists.
- <tt>-f FILE</tt> returns true if \c FILE is a regular file.
- <tt>-g FILE</tt> returns true if \c FILE has the set-group-ID bit set.
- <tt>-G FILE</tt> returns true if \c FILE exists and its group matches the effective group id of this process.
- <tt>-L FILE</tt> returns true if \c FILE is a symbolic link.
- <tt>-O FILE</tt> returns true if \c FILE exists and its owner matches the effective user id of this process.
- <tt>-p FILE</tt> returns true if \c FILE is a named pipe.
- <tt>-r FILE</tt> returns true if \c FILE is marked as readable.
- <tt>-s FILE</tt> returns true if the size of \c FILE is greater than zero.
