Hi,
I've run into an odd problem with uniq, which I've simplified to the below
example. When trying to remove duplicates from identical consecutive text lines
where there is a special byte like \xFF, it does not consider most of the lines
to be identical and passes them through. What could be causing this?
address@hidden:~> echo $BASH_VERSION
3.2.51(1)-release
address@hidden:~> echo 'aabaaa' | sed 's|b|\xFF|g' | awk '{print $1; print $1;
print $1; print $1; print $1;}' | uniq -c
2 aaÿaaa
1 aaÿaaa
1 aaÿaaa
1 aaÿaaa
Thanks,
Kit
