- $BUILTIN for
- $SHORT_DOC for NAME [in WORDS ... ;] do COMMANDS; done
- The `for' loop executes a sequence of commands for each member in a
- list of items. If `in WORDS ...;' is not present, then `in "$@"' is
- assumed. For each element in WORDS, NAME is set to that element, and
- the COMMANDS are executed.
- $END
-
- $BUILTIN case
- $SHORT_DOC case WORD in [PATTERN [| PATTERN]...) COMMANDS ;;]... esac
- Selectively execute COMMANDS based upon WORD matching PATTERN. The
- `|' is used to separate multiple patterns.
- $END
-
- $BUILTIN if
- $SHORT_DOC if COMMANDS; then COMMANDS; [else COMMANDS;] fi
- `if' executes the `then' COMMANDS only if the final command in the
- `if' COMMANDS has an exit status of zero.
- $END
-
- $BUILTIN while
- $SHORT_DOC while COMMANDS; do COMMANDS; done
- Expand and execute COMMANDS as long as the final command in the
- `while' COMMANDS has an exit status of zero.
- $END
-
- $BUILTIN until
- $SHORT_DOC until COMMANDS; do COMMANDS; done
- Expand and execute COMMANDS as long as the final command in the
- `until' COMMANDS has an exit status which is not zero.
- $END
-
- $BUILTIN function
- $SHORT_DOC function NAME { COMMANDS ; } or NAME () { COMMANDS ; }
- Create a simple command invoked by NAME which runs COMMANDS.
- Arguments on the command line along with NAME are passed to the
- function as $0 .. $n.
- $END
-
- $BUILTIN { ... }
- $SHORT_DOC { COMMANDS }
- Run a set of commands in a group. This is one way to redirect an
- entire set of commands.
- $END
-
- $BUILTIN %
- $SHORT_DOC %[DIGITS | WORD] [&]
- This is similar to the `fg' command. Resume a stopped or background
- job. If you specifiy DIGITS, then that job is used. If you specify
- WORD, then the job whose name begins with WORD is used. Following the
- job specification with a `&' places the job in the background.
