System is available with extended TCL. From tclhelp:
system cmdstr1 ?cmdstr2...?
Concatenates cmdstr1, cmdstr2 etc with space sep-
arators (see the concat command) into a single com-
mand and then evaluates the command using the stan-
dard system shell. On Unix systems, this is
/bin/sh and om Windows its command.com. The exit
code of the command is returned.
This command differs from the exec command in that
system doesn't return the executed command's stan-
dard output as the result string, and system goes
through the Unix shell to provide wildcard expan-
sion, redirection, etc, as is normal from an sh
command line.
This command is provided by Extended Tcl.
