Looking for sed commands to add some strings

Shell Programming and Scripting

Hi All,

I have one file which has contents as following. I have now to add some strings into this file. In below there is a "Description" field, and I have to look line by line and as the description contents will be finished, I have to add the string "Hello world" followed by a TAB. So before the filed "Jobs" I have to add the string "Hello world" followed by a TAB.

Change:    12345

Is this a homework assignment?

So, based on the discussion in your other thread, assuming that this isn't homework either; please show us what you have tried and (in CODE tags) please show us the output you are trying to produce. (Your description can be interpreted several ways as to where the text you want to add is supposed to appear. And, some are easier to apply than others.)

It always helps if you also tell us what operating system you're using and it is especially important with sed since some operating systems extend the behavior specified by the standards for sed in various incompatible ways.
