SYSTEM(3)           UNIX Programmer's Manual            SYSTEM(3)



NAME
     system - issue a shell command

SYNOPSIS
     system(string)
     char *string;

DESCRIPTION
     _S_y_s_t_e_m causes the _s_t_r_i_n_g to be given to _s_h(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.

SEE ALSO
     popen(3S), execve(2), wait(2)

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