in reply to perl on the commandline

The -p prints $_ after each line, while -n do not. So the two versions are almost the same (they will do the same): 
perl -i.bak -ne 's/\s+//g;print' names
perl -i.bak -pe 's/\s+//g;' names

      You are using single quotes, under windows you have to type the following: perl -pi.bak -e "s/\s+//g" names
