Given the output below (simplified) extracted from the comparison of two curl -I commands saved in two different files, I am looking for the best approach to highlight the following scenarios in a script:
this header exists only in file1.txt but this one does not
this one exists in both cases but the values are different
I was thinking about assigning green color to column 3, orange color if the header is found both in column 1 and column 2 and no color if the header is found only either in column 1 or column 2...
I am also open to suggestions different from colors and by processing file1.txt and file2.txt with other options than comm command.
See my other post on sdiff ....
I don't think sdiff is able to do what I want.
The 'comm' command does what I need and works fine as

but because of the way it starts each line... (2 Replies)

produces a bunch of IPs. Due to a DHCP scope, some of these IPs
are not useable, so I would like to eliminate them from the final list.
I have used comm to do this, but am unable to extract the first column,
and redirect it to a... (1 Reply)
