I have two files with large data with matching id at different column. I want to merge those identical columns with other values along the line. I want to merge file 1 (column 10) and file 2 (column 8)

File 1

```

Any response in any command is appreciated. Thank you in advance
Using <a href="http://linux.die.net/man/1/join">join</a> it's quite easy. Of course, you need to sort the files according to the field to join them:

    join -1 10 -2 8 <(sort -k10 FILE1) <(sort -k8 FILE2) > joined_file.txt

<p>If you want to select certain fields you can use either the -o option in the join command (-o 1.1,1.2...0,2.1,2.2...) or the cut tool on the joined file (`cut -f 1,2,3.....`)
