If + command is a shell builtin command or a shell function, the + shell executes it, and exits when the command is complete. + + With -c clear the environment; with -l prepend - to the argv[0] + string of the command executed (to simulate a login shell); with + -a argv0 set the argv[0] string of the command executed. See + the section `Precommand Modifiers' in zshmisc(1). + + If the option POSIX_BUILTINS is set, command is never inter- + preted as a shell builtin command or shell function. This means + further precommand modifiers such as builtin and noglob are also + not interpreted within the shell. Hence command is always found + by searching the command path. + + If command is omitted but any redirections are specified, then + the redirections will take effect in the current shell. |
