OA60693: The sed command may ignore the inline #n (no-autoprint) option

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If using sed with a file, and the first two characters are #n
  to enable the no-autoprint (command line -n) option, the output
  should be suppressed.
  
  Verification Steps:
  
  Using example:
     sed "$(cat command_file)" file
  
  1) Verify the first two characters of the command_file are "#n".
     Note, this must be lower case, upper case #N should be
     treated as a comment.
  2) Verify the command, continues to produce output generated
     by sed; while it should be suppressed.
  

Local fix

• Use the -n invocation on the command line.

  The #n was only processed correctly when reading the command
  from a command file in sed.
  

Problem conclusion

• After this PTF is applied, if the first two characters are
  #n, sed will turn on the no-autoprint option, no matter how
  the commands was input to sed.
