Removing empty lines in a text file - but not the other line breakes

[Larshg]

Hi

I would like to remove empty lines in a text fil, but not the other line breakes

ex. - a text file like this

./cat text.txt
test1

test3
test5

I want the output to be
test1
test3
test5

I've tryede something like this
tr '\012' ' ' < ./text.txt

but this removes all the line breakes and put everythin into one line.

Try something like this:
sed -e '/^$/d' ./text.txt

And the awk way:
awk 'NF' ./text.txt

Larshg, as you have posted a new question in this forum, I assume you have read the replies in your previous post.
It would be fair (for the members) to close your threads by saying how your problem was solved or not.
Keep in mind that you aren't in a help desk site here.

The two commands 'sed' and 'awk' doesn't do exactly the same thing

[tt]sed -e '/^$/d'[/tt] removes empty lines

[tt]awk 'NF'[/tt] removes empty lines and lines with only spaces or tabs, like :
[tt]sed '/^[[:space:]]*$/d'[/tt]

The sed equiv is :
[tt]awk -F '' 'NF'[/tt]

Thanks that did it for me.

I've usede the "awk way" - becourse I only wanted lines that contain some text

Try:
[tt]
grep -v "^$" <text.txt
[/tt]
