How to grep a line not starting with # from a file (there are two lines starting with # and normal)?
e.g.

File name: File.txt

Hello Tanu,

Welcome to forums, please use code tags for commands/cods/Inputs as per forum rules. Following may help you in same.
Code:
awk '/^#/{next} 1'  Input_file
OR
awk '/^#/{next} 1'  File.txt

Thanks,
