I have this table
gene 5 5 5
gene 4 4 3
gene 5 5 5
gene 1 4 5
and I would like to have the following,
gene 5 5 5 2
gene 4 4 3 1
gene 1 4 5 1
so in the last column I would have a number of similar rows (in this case it's gene 5 5 5
, that is present two times in the original table, while others presented only once).
What would be the best approach to do it? Is it a job for awk
? Actually, is it even possible in Linux?
