I already wrote that GNU Core Utilities (GNU Textutils) have become my favorite text processing tools. Today i wanted to sort a couple of lines using the last three numbers of each line. Here is an example

c:/data/backup/JA-229
c:/data/backup/JA-221
c:/data/backup/JA-233
c:/data/backup/NE-046
c:/data/backup/NE-049
c:/data/backup/JA-217
c:/data/backup/JA-225

With the command “sort -n -t- -k2 myfile.txt” i quickly got what i needed.
