NAME
     system - issue a shell command

SYNOPSIS
     #include <stdlib.h>

     int system(const char *string)

DESCRIPTION
     System causes the string to be given to sh(1) 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.

     sh(1), popen(3), execve(2), wait(2).

DIAGNOSTICS
     Exit status 127 indicates the shell couldn't be executed.
