Many text editors create backup files with names ending with “~”.
Most of the times these files are annoying and unnecessary…
So, you can use the following piped commands to remove them :
find / | grep "^.*~$" | sed -e 's/\(^.*$\)/"\1"/g' | xargs rm -f > /dev/null 2>&1
Please take account that this version handles correctly also filepaths containing space characters.
