Re: Unixx shel script - combing information from 2 files into one useing looping structur
 

can u explain this code please.

Re: Unixx shel script - combing information from 2 files into one useing looping structur
 

while read -r name number

do

     while read -r NAME NUM

     do

         if NAME is equal name

         then

              echo name NUM number         

     done < "file2"

done < "file1"

Basically, this pseudo code is reading the first file and grabbing the two variables, and for each line read from the first file, it's checking every line in the second file and, if the name matches, it's print the output in the format you specified to stdout.

If you need Monday to equal Mon, etc, you can do that pretty easily with sed or even cut, if you know you only need a certain number of characters in your abbreviation (like if your standard is always 3 - Monday = Mon, Tuesday = Tue, etc)

Hope that helps. Give it a shot and see what you can do with it. Remember, the code posted is pseudo-code which means it's not entirely "correct" (won't just work if you cut-and-paste it) and is meant to demonstrate a principal and provide a means to reaching the answer rather than being the answer itself.

Best wishes,

Just trying to help out so you don't get bumped off. Hope you get your problem solved soon :)

I wished I had seen this post earlier. Cause I had the same home work in my unix class.

It took me a good while, but I got it working with the for loop.

Anywho, happy scripting!...
