Arguments: &optional cmd&key show-window
The :osi
module (see Operating System
Interface Functionality in
os-interface.htm) has these operators relating to
running subprocesses: the function command-output
and the macros
with-command-output and with-command-io. They are
higher-level than run-shell-command and shell and are recommended when the
interaction with the subprocess requires input or produces output that
must be captured. Those operators do not have separate description
pages. They are described in OSI process/uid/gid interface
functions in os-interface.htm.
On Windows, an interactive shell cannot be started, so the optional cmd must be specified. In general, Windows users should consider run-shell-command or one of the OSI functions mentioned above as alternatives.
On UNIX, the shell function used by shell is /bin/sh.
If the command argument is not given, then an interactive shell is spawned. To get back to Lisp, exit from the shell. If the command (a string) is given as the value of cmd, then a shell is spawned and directed to execute that command.
The show-window keyword argument is only
applicable on Windows. It specifies how the window associated with the
cmd will be displayed. The default is
:minimized
, which produces the same behavior as in
earlier releases, which was, the window was not displayed but an entry
for it appeared on the task bar. Another possible value is
:showna
, which is supposed to display the window
but not select it. Note that the :showna
option
does not seem to work correctly on some versions of Windows. See the
description of the show-window argument to
run-shell-command for the
possible values (all values accepted by run-shell-command are valid for shell) and a discussion of the
:showna
problems.
On UNIX, the show-window keyword argument is accepted but ignored.
See also run-shell-command. See os-interface.htm for general information on the interface between Allegro CL and the operating system, and information on shell commands.
