Two files are to be compared, line by line. The first file as a list of strings to be searched, one per line.
office@meridian.az
astana@globalair.com
While the second has lines of strings where the values may appear
0 1 Romania bilete@paravion.ro
0 1 Azerbaidjan office@meridian.az
0 1 Spain bras@aerotravel.es
0 1 Uzbekistan astana@globalair.com
What is a concise script that allows to delete lines of the second file where the line includes the full string of a line in the first file?
