TextUtil Explained: Features, Uses, and Examples

1. Quick overview — what TextUtil does and when to use it.
2. Fast wins — 8–10 one-line commands for cleaning, formatting, searching, and transforming text (each with a brief example).
3. Keyboard-friendly workflows — combining TextUtil with pipes, snippets, or editor macros.
4. Automation — scripting reusable tasks (shell scripts, Makefile targets, or editor integrations).
5. Advanced tips — performance tuning, handling large files, and using regex safely.
6. Troubleshooting & common pitfalls.
7. Further resources and cheat sheet.

Example quick-win commands (assume TextUtil supports typical text-tool functions):

• Remove trailing whitespace:

textutil trim-whitespace input.txt > output.txt

• Convert tabs to spaces:

textutil detab –spaces=4 file.md > file-space.md

• Normalize line endings to LF:

textutil normalize-eol –to=lf notes.txt > notes-lf.txt

• Extract lines matching a pattern:

textutil grep “ERROR|WARN” app.log > issues.log

• Batch replace a string across files:

textutil replace –find=“TODO” –with=“DONE”.md

One 3-step workflow example (cleanup, extract, summarize):

1. Trim and normalize:

textutil trim-whitespace –in=raw.txt –out=clean.txttextutil normalize-eol –in=clean.txt –out=clean-lf.txt

2. Extract relevant lines:

textutil grep “IMPORTANT|NOTE” clean-lf.txt > notes.txt

3. Summarize (assumes a summarize command):

textutil summarize –lines=10 notes.txt > summary.txt
