The shtk_cli_set_help_command function
sets the command that a user can type to get additional help when the typed
command contains a usage error. The value set by this function is used by
shtk_cli_usage_error(3).
The message can be provided as one or more arguments as depicted by
message1 to messageN; all
arguments are concatenated together into a single line.
The following could be used to point users to a GNU Info document:
main() {
shtk_cli_set_help_command "info $(shtk_cli_progname)"
...
if [ ${#} -gt 0 ]; then
shtk_usage_error "No arguments allowed"
fi
}
And the following could be used to tell the user to access built-in documentation:
main() {
shtk_cli_set_help_command "$(shtk_cli_progname) --help"
...
if [ ${#} -gt 0 ]; then
shtk_usage_error "No arguments allowed"
fi
}
shtk_cli_set_help_command first appeared
in shtk 1.8.
