About this tool
This tool strips a known prefix and/or suffix from each line: protocol from URLs, a common path, a trailing slash or extension. Lines that do not carry the string stay as they are, and the number of removals is reported.
For positional trimming regardless of content, use Remove First/Last N Characters.
