Invocation Options
Here is a list of the options you can use when invoking the Korn shell. In addition to these, any set option can be used on the command line; see Table B.5 below. Login shells are usually invoked with the options -i (interactive), -s (read from standard input), and -m -able job control).
| Option | Meaning |
|---|---|
| -c string | Execute string, then exit. |
| -s | Read commands from the standard input. If an argument is given, this flag takes precedence (i.e., the argument won't be treated as a script name and standard input will be read). |
| -i | Interactive shell. Ignore signals TERM, INTR, and QUIT. |
| -r | Restricted shell. See Korn Shell Administration. |
