There are several of that 3 lines. I could ':sort' the file to find duplicated
lines but, what I really need to know is if there are binary data of 'pass1
key' equal to 'pass2 key' or 'passN key'. I have 3 files with more than 8000
lines each. So, visually do this is tedious and error prone. I need a little
help, please.
If you don't mind changing the file-order, I'd sort it, then use
a regexp to find the duplicate lines:
:%sort /key: /
/^.*\(key: .*\)\n.*\1$
It's a little easier to spot if you turn on search highlighting
:set hls
which should then highlight them all.
It's a lot uglier & slower if you want to leave the file unsorted
because it has to check every line with every subsequent line.
It might look something like
/^.*\(key: .*\)\ze\n\%(.*\n\)*.*\1$
It was fast on my dummy 5-line file using your data above
(duplicating one line and changing the pass#, along with a blank
line), but I suspect it would get progressively slower as your
file grows.
