Can anyone explain how to store a value returns by a linux command in a fortran local variable without using IO operations.

[Steven_L_Intel1]

The standard Fortran intrinsic EXECUTE_COMMAND_LINE does this.

An example:

integer stat
call EXECUTE_COMMAND_LINE('ls',EXITSTAT=stat)

For Intel Fortran this will require compiler version 15.0.1 or later.

Thanks Mr.Steve.But if I want to store the output of the linux command 'whoami' in a fortran variable,What should I do?

[Steven_L_Intel1]

Ah, you want to save the output. There's no way I know of to do this without using I/O. However, for this particular purpose I think that the POSIX subroutine PXFGETLOGIN might do what you want.

PXFGETLOGIN

POSIX Subroutine: Gets the name of the user.

Module

USE IFPOSIX

CALL PXFGETLOGIN (s,ilen,ierror)

s	(Output) Character. The returned user name.
ilen	(Output) INTEGER(4). The length of the string stored in s.
ierror	(Output) INTEGER(4). The error status.

If successful, ierror is set to zero; otherwise, an error code.
