Greetings all. :)
I would like to use sed to join all non-blank lines together in a particular file. I was thinking I could do this by simply replacing the terminating, new-line character on every line which is not blank, but I must be missing something in my sed line:

I want to use SED to replace all new line characters of a file, I googled and found this one liner
sed '{:q;N;s/\n//g;t q}' infile

Can anyone explain the below sed oneliner?
sed -e ':a' -e '$q;N;11,$D;ba'
It works same as tail command.
I just want to know how it works.
Thanks

BBB Thing2
CCC Thing3

BBB678
CCC2345

AAA234 Thing1
BBB678 Thing2... (5 Replies)

Hi,
I have the following command.(Delete all trailing blank lines at the end of a file.)
sed -e :a -e '/^\n*$/{$d;N;ba' -e '}'
I don't understand the logic of this command and also I don't understand why -e is used.
Can you please let me know the logic of this command and why three -e... (5 Replies)
