Return codes for a single command

A single command is normally typed from a command prompt such as a DOS command prompt, Korn shell prompt, and C shell prompt. Single command mode does not automatically display the 0 or 1 return code values; the operating system must be queried for the return code value. For command failures, the hexadecimal error code status with its associated error message is shown in addition to the error message ID (for example, HPDMG0754W). We can redirect the error that is normally displayed on the screen out to a text file. When a single command fails, you see an error message that is like the one displayed:

C:> pdadmin -a admin_id -p password user show oogle

Could not perform the administration request.
Error: HPDMG0754WThe entry was not found. If ...
(status 0x14c012f2)

To display the 0 or 1 return code values, type the pdadmin command, followed by either the AIX®, Linux®, or Solaris echo or the Windows errorlevel command:

• For AIX, Linux, and Solaris operating systems:

  # pdadmin_command
  # echo $?

For Windows operating systems:

C:>pdadmin_command
C:>echo %errorlevel%
