       system cmdstr1 ?cmdstr2...?
              Concatenates   cmdstr1,   cmdstr2  etc  with  space
              separators (see the concat command) into  a  single
              command  and  then  evaluates the command using the
              standard 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
              standard output as the result  string,  and  system
              goes  through  the  Unix  shell to provide wildcard
              expansion, redirection, etc, as is normal  from  an
              sh command line.
