To do this, go to the desired directory, for example:

cd /root

Then create a file with the help of an editor and copy the relevant file codes into it and save the file. For example with this name:

nano test123.file

Finally, by executing the following command, all lines that started with # are deleted completely:

sed -i '/^#/d' test123.file
