How to Remove Empty Lines from a File on Ubuntu?

Our sample file should be like this – Use the following command to remove the Empty lines from a file as shown below –

$ ex -s +'v/\S/d' -cwq abc.txt

In the above command abc.txt indicates the file name. The sample output should be like this – To create a new file without empty lines from the previous file, use the following command –

$ awk 'NF > 0' abc.txt > bbc.txt

In the above command, it creates a file called bbc.txt and copies the whole content from abc.txt without empty lines. To verify the file, use the following command –

$ nano bbc.txt
