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.
