Thanks for your efforts, edidataguy. However, the result is the following:

Sorry, could not come back to you early. Got tied up.
OK. Looks like there is as issue with your version of sed recognizing the "\t" (tab) and \n (new line). Try it this way, replace all \t with \\t and \n with \\n. See if it works.

Hi editaguy. I don't think the problem's with sed:

Code:
 
# sed  '/ceName:.*/d; s/^[^:]*: //' 3rdline.txt | sed 'N;N;N;s/\n/\\t/g; s/\([^\\t]*\\t\)//3'
tzMgmt\tPROCESS_NOT_RUNNING\ttzMgmtPROCESS_RUNNING
XDM\tPROCESS_NOT_RUNNING\tPROCESS_RUNNING

There are additional '\t's now. I think I may have to resort to arrays.
