NAME

system − execute a UNIX command

SYNOPSIS

integer function system (string)
character∗(∗) string

DESCRIPTION

System causes string to be given to your shell as input as if the string had been typed as a command.  If environment variable SHELL is found, its value will be used as the command interpreter (shell); otherwise sh(1) is used.

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