rsriram has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

This is another question relating to the content, which I seeked help before. I have a text file, which has less than 100 lines and I need to sort this based on the second column.

I can add each line to a array and sort it, but it is sorting only based on the first column. Can anyone help me?

The output needs to look similar to this
