[tlug] sorting data set -Help

["John Joseph" <johnjoseph.e@example.com>]

Hello,
I am a new linux user. Would like to sort the data set by selecting
rows containing different set of first few letters or words. Example
of data set is given below. Wondering how do I select and write
those rows statrting with "$TKACC"; "$TKGPP" and "$TKATT".
My data file is quite large size.
