     SYSTEM(S)                 UNIX System V                 SYSTEM(S)



     Name
          system - issue a shell command

     Syntax
          #include <stdio.h>

          int system (string)
          char *string;

     Description
          The system function causes the string to be given to sh(C)
          as input, as if the string had been typed as a command at a
          terminal.  The current process waits until the shell has
          completed, then returns the exit status of the shell.

     Files
          /bin/sh

     See Also
          exec(S), sh(C)

     Diagnostics
          The system function forks to create a child process that in
          turn exec's /bin/sh in order to execute string.  If the fork
          or exec fails, system returns a negative value and sets
          errno.

          system is conformant with:
