Frequently Asked Questions
Does it remove blank lines?
If blank lines are identical, they will be collapsed into a single blank line. If you want to remove all blank lines entirely, you would need a different filter tool.
Is it case-sensitive?
Yes, this version is case-sensitive. 'Apple' and 'apple' would be considered distinct lines.
