Strip a prefix string from the start of every line.

How do you remove a prefix from each line?
Feed it a bulleted list and the marker comes off every line: “- apples” becomes “apples” when you set the prefix to “- ”, dash and space included. Lines that never had the prefix are left alone rather than trimmed blindly, and the match is case-sensitive, so “INFO:” and “info:” are treated as different prefixes. The natural undo for the add-prefix tool.
How to use the Remove Prefix
- 1 Paste the list whose lines carry an unwanted start.
- 2 Enter the exact prefix, including any trailing space (“- ” for dash bullets).
- 3 Lines beginning with that string lose it; the rest stay put.
- 4 Copy the stripped list.
What you can use it for
- Taking bullet markers like “- ” off a list.
- Stripping a repeated label from each line.
- Cleaning numbering or tags off log lines.
- Reversing an earlier add-prefix pass.
Frequently asked questions
What about lines that lack the prefix?
They pass through untouched. The tool never trims characters blindly; it removes the string only where the line genuinely starts with it.
Does “Info:” match a line starting with “info:”?
No. Comparison is exact, capitalisation included, so run separate passes if your data mixes cases.
How do I remove a bullet and its space together?
Enter the prefix as “- ” with the trailing space. Whatever you type, spaces included, is what gets cut.
