### Arguments ### Arguments
| Expression | Description | | Expression | Description |
| --- | --- | | --- | --- |
| `$#` | Number of arguments | | `$#` | Number of arguments |
| `$*` | All arguments | | `$*` | All postional arguments (as a single word) |
| `$@` | All arguments, starting from first | | `$@` | All postitional arguments (as separate strings) |
| `$1` | First argument | | `$1` | First argument |
| `$_` | Last argument of the previous command | | `$_` | Last argument of the previous command |
**Note**: `$@` and `$*` must be quoted in order to perform as described.
Otherwise, they do exactly the same thing (arguments as separate strings).
