Not removed entirely from the file itself, but from the output of the
uniq utility report. I keep a textfile in which to give visual emphasis
to some lines I duplicate them a few times. I want to use uniq utility
to make a little report of the duplicate contents of the file, so far I
know I need to use something like
uniq -c -d file
But the problem is that it reports the leading lines too. I found a
sortu utility online that has a -b option to ignore blank lines but i'd
rather use the standard ones.
I just did a piping
sort file | uniq -c -d | sort -r
This gives me the duplicated lines in my file sorted by how many times
they're duplicated, but the first item I get are how many blank lines
there are in my file, which I don't need to know.
Can I improve on this?
