如何执行系统命令

1.

DATA: commtext(120) ,
      itab(255) OCCURS 10 WITH HEADER LINE.

commtext = 'ls /usr'.

CALL 'SYSTEM'
  ID 'COMMAND' FIELD commtext
  ID 'TAB' FIELD itab-*sys*.

LOOP AT itab.
  WRITE itab.
ENDLOOP.

 

2.

看函数组：SXPT

 

例子：

  REPORT  z_barry_test7.

DATA : itab_btcxpm LIKE btcxpm OCCURS 0 WITH HEADER LINE.

CALL FUNCTION 'SXPG_CALL_SYSTEM'
  EXPORTING
    commandname                = 'LIST_DB2DUMP'
    additional_parameters      = '/usr'
  TABLES
    exec_protocol              = itab_btcxpm
  EXCEPTIONS
    no_permission              = 1
    command_not_found          = 2
    parameters_too_long        = 3
    security_risk              = 4
    wrong_check_call_interface = 5
    program_start_error        = 6
    program_termination_error  = 7
    x_error                    = 8
    parameter_expected         = 9
    too_many_parameters        = 10
    illegal_command            = 11
    OTHERS                     = 12.
LOOP AT itab_btcxpm .
  WRITE / itab_btcxpm-message .
ENDLOOP.
