Learn Advanced Bash by Building a Kitty Ipsum Translator

Im stuck on:

" It’s showing the line number of each match it found. grep can use regular expressions, too. Enter the previous command, but change the pattern to meow[a-z]* to see all words that start with meow ."
Even when I try to type command from hint:
grep --color -n 'meow[a-z]*' kitty_ipsum_1.txt
it says “You should enter the suggested command”. I am not able to go further…
What should I do?

Today the same command works just fine :slight_smile:
grep --color -n 'meow[a-z]*' kitty_ipsum_1.txt
