{title:Description}

{pstd}
{opt shell} (synonym:  "{cmd:!}") allows you to send commands to your
operating system or to enter your operating system for interactive use.  In
Stata for Macintosh, the {it: operating_system_command} is required.

{pstd}
{opt winexec} allows you to start other programs (such as browsers) from
Stata's command line and without Stata waiting for the program to
complete before continuing.

{pstd}
{opt xshell} (Stata for Unix(GUI) only) brings up an {opt xterm} in which
the command is to be executed.
