I have files in a folder where the filenames are of the form:
2352_GF_somerandomstring.txt, i.e. someNumber_twoletters_somestring.
using flags on ls the best I can achieve is to sort by different criteria similarly for sort.
What I'd like is to have the list sorted by the 'twoletters'. I.e. ignore the prefix-number and sort by the 'GF'-portion (in the sample), but still show me the complete file names (i.e. including the prefix-number).
The closest I got is (without writing a complete script):
ls | cut -d '_' -f2- |sort
but the cut part removes everything in front, which I still need to see.
Any ideas on how to do this in a simple way? (Hopefully a oneliner).
like this:
ls | sort -t '_' -k 2
-t is separator and -k is column
