NAME

     sh - fast execution of an sh shell command

SYNOPSIS

     integer function sh (string)
     character*(*) string

DESCRIPTION

     The function sh gives string to the sh shell as input, as if
     the string had been typed as a command.

     The shell is always the Bourne shell, sh(1).

     The current process waits until the command terminates.  The
     returned value is the exit status of the shell.  See wait(2)
     for an explanation of this value.

     The functions sh(3f) and system(3f) pass the argument string
     to  a shell for execution.  They convert the argument string
     from a Fortran character value to a C string value and  pass
     it to the C routine system(3c).

     The routines sh(3f) and system(3f)  differ  in  that  system
     flushes the Fortran I/O buffers before calling the C routine
     system, while sh does not.  Flushing the  buffers  can  take
     significant   time,   and  so,  if  any  Fortran  output  is
     irrelevant to the result of the call, the routine sh is pre-
     ferred over the routine system.

     Note that both sh(3f) and system(3f) return integer results.
     Therefore, they must be declared to be of type INTEGER.
