to execute from ABAP code an external Unix program

[Former Member]

HI,

I would like to know how to execute from ABAP code an external Unix program and check for a return code?

HI,

There are different ways to this:

(1) OPEN DATASET <file> FOR OUTPUT 'unix command'

CLOSE DATASET <file>

This command executes the unix command and writes the output into <file>

Look into OSS Note 9391.

(2) or try the following program but unfortunately the command CALL SYSTEM is

not supported by SAP. If you are on R/3 2.1 - 2.2x you can get some idea's from the program SAPMSOS0.

REPORT ZUNIXCOM .

DATA: U_COMMAND(200).

• Table for system messages

DATA: BEGIN OF RT OCCURS 100 ,

LINE(100) ,

END OF RT .

START-OF-SELECTION .

MOVE 'unix command' to U_COMMAND .

REFRESH RT.

CALL 'SYSTEM' ID 'COMMAND' FIELD U_COMMAND

ID 'TAB' FIELD RT-SYS .

LOOP AT RT.

WRITE : / RT-LINE .

ENDLOOP.

Reward Points if found helpfull..

Cheers,

Chandra Sekhar.
