Unix Join Command Multiple Files

Simple method (no awk, join, sed, or perl), using software tools cut, grep, and sort: cut -d ' ' -f1-3 File1 grep -h -f - File1 File2 sort -t ' ' -k 1,2g Output (does not print unmatched lines): bar 2 scaf 1.00 bar 2 scaf 3.3 foo 1 scaf 3 foo 1 scaf 4.5 How it works. • cut makes a list of all the lines to search for. • grep's -f - switch inputs the lines from cut and searches File1 and File2 for them. • sort isn't necessary, but makes the data easier to read. Condensed results with datamash: cut -d ' ' -f1-3 File1 grep -h -f - File1 File2 datamash -t ' ' -s -g1,2,3 collapse 4 Output: bar 2 scaf 3.3,1.00 foo 1 scaf 3,4.5 If File1 is huge and is somewhat redundant, adding sort -u should speed things up: cut -d ' ' -f1-3 File1 sort -u grep -h -f - File1 File2 sort -t ' ' -k 1,2g.
