UNIX tip – xargs with multiple commands

Xargs is an extremely powerful complement to the awesome find command. One downside is that you usually need to have a single pipeline. By default you can’t put together a bunch of commands which are not piped. However, it is possible to call a shell with xargs. In this way, you can execute multiple commands in this shell, but from xargs point of view, it is calling a single command – the shell interpreter. More details here:
