runargv0 - run a program with a different 0th argument
runargv0 [-hV] realprog alias [ args ... ]
runargv0 runs realprog with the 0th argument set to alias.
Any options and/or arguments for realprog may be given in args.
If realprog does not contain a ``/'' slash character,
runargv0 will perform a shell-like search for the executable using
the PATH variable in the current environment.
- -h
- Help. Print a brief usage message to stderr and exit.
- -V
- Version. Print the version number to stderr and exit.
runargv0 exits with one of the following values:
- 0
- realprog was invoked and completed successfully. In this case, the
exit code is returned by the program, rather than by
runargv0 itself.
- 100
- runargv0 failed because of a usage error, such as an invalid
command-line option or argument. In this case, runargv0 prints a
brief error message and usage help to stderr on exit.
- 111
- runargv0 failed due to some system or resource error. In this case,
runargv0 prints a brief diagnostic message to stderr on exit.
- 1-127
- program was invoked and failed with its own non-zero exit
status.
