It turned out that echo -n trick isn't correct neither. I've decided to add the second condition for empty string, so the final version is:
echo -n
TO_REMOVE=`git clean -f -d -n`; if [[ "$TO_REMOVE" != "" ]] && [[ `echo $TO_REMOVE | wc -l | bc` != "0" ]]; then
What about wc -l "$TO_REMOVE"?
wc -l "$TO_REMOVE"
I don't think it gonna work. It tries to read a file under the path saved in $TO_REMOVE variable. That's not what we want to do.
$TO_REMOVE
Oh interesting. Never mind then. Thanks for helping me understand all of this.
