Change file permission

[former_member1033672]

Hi, Im using open dataset, transfer, close dataset to write data on unix server. Problem is, that all files i write by this ABAP command, have permission 660. I want to set it to 644. Is it possible, if I am not allowed to use unix commands in ABAP?

Hi,

Create one external unix command in SM69.

In that transaction, input "chmod" in the "Operation system command" field.

in the "Parameters for operating system command" input "644 &"

Lets say the external command you created is "'ZFMM_CHMOD1'".

Now we need to call this in ABAP.

data: w_output TYPE SXPGCOLIST-PARAMETERS VALUE '/tmp/swa.txt' ,

w_command TYPE SXPGCOLIST-name VALUE 'ZFMM_CHMOD1'.

 CALL FUNCTION 'SXPG_COMMAND_EXECUTE'
  EXPORTING
    commandname                         = w_command
    ADDITIONAL_PARAMETERS               = w_output
 IMPORTING
   STATUS                               = w_status
 TABLES
   EXEC_PROTOCOL                        =  LOG

it looks good. I wrote this code but still there is some bug, because it returns me exception COMMAND_NOT_FOUND. But i created it in SM69. Mayby problem is, that i didn't create transport for that command... or mayby something with authorization on unix?

REPORT ytest.

you can even use this..

REPORT ZUNIX line-size 400
                no standard page heading.
 
 
data : unixcom like   rlgrap-filename.   
 
 
data: begin of tabl occurs 500,
        line(400),
      end of tabl.
 
data: lines type i.
  
*----------------------------------------------------------------------
 
start-of-selection.
  refresh tabl.
 unixcom = 'CHMOD 644 filefullpath'.

  call 'SYSTEM' id 'COMMAND' field unixcom
                id 'TAB'     field tabl[].
 
 "if there is any error then you can get the error details in tbal
 "Loop the tabl and write the results.

2Vijay: it returns sy-subrc = -1. What it means, when sy-subrc is with minus?
