UNIX for Dummies Questions & Answers

Hi Everyone,

I am looking for the unix command by which I can view 5 lines after the last occurence of a string (including the last occurence)

Example : I have the following lines in a unix file. I have to look for the last occurence of the string "How are you" and then view the next 5 lines from there. (Looking to print lines 6 to 10) What would be the command?

Line 1: Hi
Line 2: How are you
Line 3: Very good
Line 4: How are you
Line 5: Welcome to Unix Forum
Line 6: How are you
Line 7: Learn Many things here
Line 8: Hi
Line 9: My Name is Kannan
Line 10: Very good
Line 11: Test
Line 12: Welcome to Unix Forum
Line 13: Good
Line 7: Learn Many things here

What's your system?

The system is Unix and I am accessing it using Putty

"What system are you using?"
"UNIX"
"What model is your car?"
"Blue"

Those are both very vague answers.

If you don't know, try uname -a, it will print more details.

If your system, whatever it is, has bash or ksh, you can try this:

Code:

#!/bin/ksh

exec 5>/tmp/$$
while read LINE
do
        [[ "$LINE" == *"How are you"* ]] && exec 5>/tmp/$$
        echo "$LINE" >&5
done

head -n 6 /tmp/$$
exec 5>&-
rm /tmp/$$

I am sorry for the wrong reply. I dont know these jargans .

uname -a returns this:-
Linux hn731c2n8 2.6.9-89.0.2.EL.msdw.1largesmp #1 SMP Fri Jun 12 15:15:13 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

And I have ksh and bash in my system.

Thanks for the answer. It looks like a shell script. Is there a command as simple as a grep command to return the result that I am looking for?

Code:

grep -A 5 'How are you' FILENAME | tail -6

Replace FILENAME with your filename. I hope you have the -A option in grep !
