Hi everyone,

Does there exist any way under shell programming to capture a line (say
line 13 ) and save it
to a string and manipulate? As an example of the functionality that i
am looking for:
Suppose you a terminal with display like this:

Hello everyone

Unix Shell Scripting

When i run my script, i would like to get line 3(displayed ) and save
it to string for further manipulation.
