Isolating catalog entries

If we need to search for one entry, then we need more than just one line. The entry is in three lines. So, if we search for the hammer, we need to go to the hammer line and the two lines that follow.

$ parsecsv.sh tool | grep -A2 hammer  

This is displayed in the following screenshot:
