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.
