Do not use parenthesis when explaining you are “flagging the text with…” (**), when you are actually flagging it with just **. The special code formatting (the pink text box) already depicts that meaning. Putting extra parenthesis just makes it more cumbersome.
The same is for “(and)” and “(or)” in the third paragraph.

@Ren

The line is:
7 Nano_Prowler_Mini_Drone $36.99 Tech

Not:

7 Nano_Prowler_Mini_Drone $3.99 Tech

So it is supposed to be printed with a “*” since it is above $20

I think $ awk '($3 ~ /^\$[2-9][0-9]*\.[0-9][0-9]$/) && ($4=="Tech") { printf "%s\t%s\n",$0,"*"; } ' tecmint_deals.txt should change to $ awk '($3 ~ /^\$[2-9][0-9]+\.[0-9][0-9]$/) && ($4=="Tech") { printf "%s\t%s\n",$0,"*"; } ' tecmint_deals.txt otherwise, the following line will also printed with "*": 7 Nano_Prowler_Mini_Drone $3.99 Tech P.S. Sorry for my English.
