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. 

For output files, the buffer is flushed to the actual file. 

For input files, the position of the pointer is unpredictable. 

The sh function is not MT-safe.  Do not call it from FORTRAN MP programs.
