GREP
 

Hi Linux Gurus
Could someone tell me how I can grep all uncommented lines in a file on linux?

Thank you in advance.

What have you done so far?

You should look at the "-v" option of grep, and the "^" regex pattern.

I have used 'egrep -v '^#' file.conf' but the problem is that it has so many blank lines/spaces. Any suggstion?

So, what is your problem?
What are you REALLY trying to do?

Are you saying that you want to remove blank lines as well?

Will show only uncommented lines, with no blank lines.

This will exclude comment lines with leading spaces, TABs and so on (if any) and empty lines with spaces (if any). It will preserve lines of code with trailing comments:
