## Description
|
|
|
|
The `Shell` utility is a command language interpreter, which reads commands from either a command string, a specified file, or the standard input.
|
|
The command language shall be described in [`Shell`(5)](help://man/5/Shell), _The Shell Command Language_.
|
|
|
|
Any extra arguments passed into `arguments` are placed in the local variable `$ARGV` and can also be accessed through the special variable `$*`.
|
|
|
|
**NOTE**:
|
|
|
|
The `Shell` utility does not promise POSIX `sh` interoperability.
|
|
|
|
## Options
|
|
|
|
* `-c`, `--command-string`: Executes the given string as a command and exits
|
|
* `--skip-shellrc`: Skips running the initialization file (at `~/.shellrc`)
|
|
* `--format`: Format shell code from the given file and print the result to standard output
|
|
* `-f`, `--live-formatting`: Enable live formatting of the line editor buffer (in REPL mode)
|
|
* `--keep-open`: Keep the shell open after running the specified command or file
|
|
* `--posix`: Behave like a POSIX-compatible shell
|
|
|
|
## Examples
|
|
|
|
```sh
|
|
# Start an interactive REPL, ignoring the shellrc
|
|
Shell --skip-shellrc
|
|
|
|
# Execute a given string
|
|
Shell -c 'rm foo*'
|
|
|
|
# Execute the contents of a file with some arguments
|
|
Shell foo a b c
|
|
```
