which returns the pathnames of the files (or links) which would be executed in the current environment, had its arguments been given as commands in a strictly POSIX-conformant shell. It does this by searching the PATH for executable files matching the names of the arguments. It does not canonicalize path names.

EXIT STATUS

0: if all specified commands are found and executable
1: if one or more specified commands is nonexistent or not executable
2: if an invalid option is specified
