How to call a bash command from within a perl script?

Shell Programming and Scripting

In a bash script, one can call a perl command in the following manner, where "myperlcommand" is a perl command.

perl -e 'myperlcommand(arguments)'

perl -e 'print("UUUU"x4)'

Now, how can one call a bash command from within a perl script? (Suppose that mybashcommand is a bash command that I would like to call.)

Many thanks in advance.
