Is there any suggestions for the same problem on HP-UX.
grep in HP-UX dosent have options like 'A' or 'B'...tried in the man page but it says nothin about the line number or the way to get the adjacent lines printed!!!!!!!!

hi there,

afaik nope. you could try the parameter '-n'. getting the line number that matches you could write a script with head + tail to get the adjacents lines. i believe should exist a better solution for that. hope some guru can give you the answer.

Ask your sysadmin team if the GNU tools are installed, usually under /opt, but could be anywhere.
Then ensure that path is added to your PATH env variable.
The flags you're looking for are GNU extensions.
