SYSTEM — Execute a shell command

SYSTEM()

Passes the command COMMAND to a shell (see system(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.

Parameters

• COMMAND – Shall be of default CHARACTER type.

• STATUS – (Optional) Shall be of default INTEGER type.

Standard:

GNU extension

Class:

Subroutine, function

Syntax:

CALL SYSTEM(COMMAND [, STATUS])
STATUS = SYSTEM(COMMAND)

EXECUTE_COMMAND_LINE, which is part of the Fortran 2008 standard and should considered in new code for future portability.
