Nested bash loop runs but logic is not correct

I have this nested bash for loop where the first loop represents the range of servers, and the second loop reads each lines of the .txt file. Then will do a zgrep -i and find for a string on the matching line.

keys.txt is as follow:

1121313232323-1
1121313244234-1
1121867575757-1

Bash Loops:

for i in {1..80}; do for j in `cat keys.txt`; do zgrep -i 'InitialRequest' /var/logs/server$i/* >> /var/log/result.log; done; done & 

This runs but its logging every instance where ‘InitialRequest’ is defined. What im looking for is to only log lines where the key line is matched to ‘InitialRequest’ with their key value.

The result i’m expecting is like this (with Key value from J inner loop 1121313232323-1 and with string ‘InitialRequest’ plus the remaining of the line:

1121313232323-1 InitialRequest http://someramdomurl.com

What I’m getting is like (just the matching string without the Key value from the J inner loop:

InitialRequest http://someramdomurl.com
InitialRequest http://someotherramdomurl.com
InitialRequest http://someotherotherramdomurl.com

Can anyone advise where is my error?

Your code is not zgreping $j in the files. For better clarity I will replace $i with $server and $j with $key in my answer. Check it out:

for server in server{1..80}; do
    for key in $(cat keys.txt); do
        zgrep -i "$key InitialRequest" /var/logs/$server/* >>/var/log/result.log
    done
done

But since you are always using the same keys, you just need to read them once. Here is a better version:

keys=($(cat keys.txt))

for server in server{1..80}; do
    for key in ${keys[*]}; do
        zgrep -i "$key InitialRequest" /var/logs/$server/* >>/var/log/result.log
    done
done
