Hello,
I have 2 files say
File 1 has
ABC
DEF
GHI
File 2 has
123
456
789

I need output as
ABC 123
DEF 456
GHI 789

I tried awk and sed but not able to get it in the right way.
Please help. Thanks

paste file1 file2 > joined_file

That helps, Thanks. I am looking for some thing like, even if 123 is in a different line on file2, it has to print next to ABC.
What I am trying to do is, I am doing ls -lrt on two directories which have same files ,and printing filename and the size to a file.
Now I want those two files with filename and filesize to be in the output file so that I can compare the file sizes.
When I say paste, it works when there are exactly same files in the directories, but if there is an extra file in any one dir, the pattern changes.

Any ideas ???

You could try something like this:

    printf "%-40s %-15s %-15s %-15s\n" "File" "Size Location 1" "Size Location 2" "Difference"
    print "========================================" "===============" "===============" "==============="
    for i in $(ls -1F /your/first/path)
    do
        [[ ${i} = */ ]] && continue
        FILE_SIZE_1=$(ls -l /your/first/path/${i} | nawk '{print $5}')
        FILE_SIZE_2=$(ls -l /your/second/path/${i} | nawk '{print $5}')
        printf "%-40s %15d %15d %15d\n" "${i}" "$FILE_SIZE_1" "$FILE_SIZE_2" "$(( FILE_SIZE_1 - FILE_SIZE_2 ))"
    done

Thank you very much, 'tmarikle'. It really helped and I am trying to extend your script for recursively checking in any/all of the directories also under the path. Not able to make the loop work. Can you advise?

Thanks

What does your loop look like now? What habe you tried?
