If I have 6 files, each file only has one column (gene ID), I want to extracted the intersection for those 6 files, which command should I use? I know the below command can work for 2 files, but not for 6 files:
cat file1 file2 | sort | uniq -d > intersection.out
Thanks and have a great day!
cat file1 file2 file3 file4 file5 file6 | sort | uniq -c | perl -lae 'print "$F" if ($F == 6)' > intersection.out
