Count the number of lines in a File in UNIX
UNIX doesn't have any real command which helps us to get the number of lines which has records or data in it. But what UNIX offers is to get the number of new lines.

Hi Nikolas, Your command would escape the empty lines, but it will fail in the below scenario: 1.Make a file with 2 records one on each line Example: name.dat Rafael (press Enter) Zin (dont press Enter) 2. After the data in 2nd line dont press enter. As discussed above. 3. Now run your command you will get wrong output.

Nope. After fixing all the typos in your script ('gerp' vs 'grep' and a few missing backticks) it returns the same result.

And another typo: "$nl_coun2" vs "$nl_count2"
