! <shell command>
... `<shell command>` ...

Shell commands can be executed within Pyxplot by prefixing them with pling (!) characters, as in the example:

!mkdir foo

As an alternative, back-quotes (‘) can be used to substitute the output of a shell command into a Pyxplot command, as in the example:

set xlabel `echo "'" ; ls ; echo "'"`

Note that back-quotes cannot be used inside quote characters, and so the following would not work:

set xlabel '`ls`'
