SYSTEM
— Execute a shell commandsystem(3)
). If argument STATUS is present, it contains the value returned by system(3)
, which is presumably 0 if the shell command succeeded. Note that which shell is used to invoke the command is system-dependent and environment-dependent. This intrinsic is provided in both subroutine and function forms; however, only one form can be used in any given program unit.
Note that the system
function need not be thread-safe. It is the responsibility of the user to ensure that system
is not called concurrently.
CALL SYSTEM(COMMAND [, STATUS]) |
STATUS = SYSTEM(COMMAND) |
COMMAND | Shall be of default CHARACTER type. |
STATUS | (Optional) Shall be of default INTEGER type. |
