Hi,

could someone, please, help me how to delete all lines in a text file that start with something different than "http://" or "https://".

Any help is greatly appreciated.

Have a look at this:

Code:

sed -ni '/^http[s]*:\/\//p' infile

Or this:

Code:

sed -i '/^http[s]*:\/\//!d' infile

A bit late, but there is always "egrep -v '^http:|^https' <filename>"
