| -a continue to search the PATH until all instances of a program file are found. |
| -h print help message |
| -p returns the PATH and ALIASES defined by non-interactive shell |
| -s suppress messages to standard output |
| -v enable output of error messages |

A diagnostic is given for names which are aliased to more than a single word, or if an executable file with the argument name was not found in the path.
