Removing last blank line

Question

There is a para break at the end of my .csv file. I tried to remove the blank line that is at the end of the file using the following command.

sed -i \'/^$/d\' c         


        

Answer 1

Try ${/^$/d;} this will only match an empty line if it is the last line of the file.

I tried it with sed (GNU sed) 4.2.2 and got all blank lines deleted not only the empty line if it is the last line of the file.

I found the following Command, that worked for myself that does the Job.

sed -e :a -e '/^\n*$/{$d;N;ba' -e '}'

This Command is from a Collection of useful SED-Oneliners: http://sed.sourceforge.net/sed1line.txt
