For Loop Question
I am struggling with the for loop. I have a file name heros.txt and I would like to go through a list in file where.txt and see if I can find the name from where inside heros.

One of the problems that I am having is I dont understand how to setup the for loop to find the list to search.Smilie

Then after that be able to print out the name and reason for why they did not show up.

I have been playing with grep but it is taking the names separated by space. I will search for Parker, then Peter not just Parker, Peter.

Any help would be appreciated


Files:
heros.txt
Code:
America, Captain 54329876 09 A A Sick
Rogers, Steve 542986 09 A A NOT HERE
Man, Spider 5432986 04 A B Couldnt get his webbing out
Parker, Peter 05 A G Lost his camera
Man, Super 98 A T Kryptonite was under his bed
Clark, Kent 43 F R Lost Keys
Pool, Dead 69 F U Lost voice
Wilson, Wade 69 U F 9:15 - 10:15 Dr's

where.txt
Code:
Rogers, Steve
Parker, Peter
Clark, Kent
Wilson, Wade

use grep -f <file with patterns to find>
Code:
grep -f where.txt heros.txt > newfile.txt

It is just printing the heros.txt file. I even tried (awk '{ print $1, $2 }' heros.txt | grep -f where.txt) but it also just printed heros.txt information.

How do I get it to search the names from lines in wheres.txt file against the hereos.txt file to output the matching names?

Jim's command worked for me to select just the particular lines from heros.txt based on what is in where.txt. It does output the whole line from heros.txt, but only the lines with a matching hero name. Are you wanting it to only output the names? or does grep not work as expected for you?

You also mention "for loop". Are you trying to program this in some language? Which language?

I am making a bash script. I need to scan to see if people are on an absent list and the last part gives a description of why they are not there. I took me a minute to get it from a pdf file to a .txt file to scan. In the program I want to run it ./program todaylistpm.pdf and it will convert and find the user. Maybe have it send it to me as an email down the road..

When I run
Code:
grep -f where.txt heros.txt > newfile.txt

I get :
Code:
America, Captain 54329876 09 A A Sick
Rogers, Steve 542986 09 A A NOT HERE
Man, Spider 5432986 04 A B Couldnt get his webbing out
Parker, Peter 05 A G Lost his camera
Man, Super 98 A T Kryptonite was under his bed
Clark, Kent 43 F R Lost Keys

Ok, after installing Centos 6.2 I found that grep worked the way it should have. I dont think it like what ever what in my ubuntu box.

Ref post #5. Should be grep -F not grep -f .
