### combine commands with *xargs*

Some commands (e.g. `chmod`) can't handle input via pipe and require the input as arguments. `xargs` takes the standard input as list of arguments seperated by spaces or newlines and executes the given command with the input parsed to a list of arguments.

Usage:
```bash
find . -type f | xargs chmod 644
```

### pipe output into clipboard

> requires `xclip`

One can save command output to the clipboard by piping it to `xclip`:

```sh
# usage
command | xclip -selection clipboard

# working example with 'echo'
echo "hello world" | xclip -selection clipboard
```

> NOTE: the argument `-selection clipboard` is required
