SHELL SCRIPTING

so i have a for loop in a bash script:

for var in file; do
   echo $var
   continue
done

the file contains plain text:
11111111
22222222
3333 3333
44444444

the output should exactly look like the input file, but the above for loop gives me that:
11111111
22222222
3333
3333
44444444

tl;dr:
so how do i make for ignore the space?

sed -e s/  *//g'


Or 's/ +//g' if you're a PERLIST.
