From Zero to Command in 4 Steps
Get started in under a minute
1
Install in 30 seconds
Terminal
$ bash <(curl --proto '=https' --tlsv1.2 -sSfL https://setup.caro.sh)
Installing caro... Done! Run `caro --help` to get started.
2
Try your first command
Terminal
$ caro "show files modified in the last hour"
Generated command: find . -mmin -60 -type f -ls Execute? (y/N)
3
Learn what it does
Terminal
$ caro --explain "show files modified in the last hour"
Command: find . -mmin -60 -type f -ls Breakdown: find . - Start searching from current directory -mmin -60 - Modified within last 60 minutes -type f - Only regular files (not directories) -ls - List in long format with details
4
See safety in action
Terminal
$ caro "delete everything in the current directory"
Generated command: rm -rf ./* BLOCKED: Dangerous pattern detected Risk Level: HIGH Pattern: Bulk deletion with wildcard Safer alternatives: - Be specific: rm -rf ./build ./dist - Use trash: trash ./* - Test first: ls ./*
Natural Language to Commands
50+ examples across common tasks
File Operations
You say: "find all javascript files modified today"
↓
Caro generates:
find . -name "*.js" -mtime 0 -type f -name for pattern, -mtime 0 for today, -type f for files only
You say: "show me the 10 largest files in this directory"
↓
Caro generates:
du -ah . | sort -rh | head -10 du -ah shows all files with human sizes, sort -rh sorts reverse by human number
You say: "delete all node_modules folders recursively"
↓
Caro generates:
find . -name "node_modules" -type d -prune -exec rm -rf {} + -prune prevents descending into matched dirs, + batches rm calls

↓
Caro generates:
find . -name "*.py" -type f -exec cat {} + | wc -l cat all Python files together, count total lines
You say: "find duplicate files by content"
↓
Caro generates:
find . -type f -exec md5sum {} + | sort | uniq -d -w32 md5sum for content hash, uniq -d shows duplicates, -w32 compares first 32 chars
You say: "backup my config files to a dated folder"
↓
Caro generates:
tar -czvf "config-backup-$(date +%Y%m%d).tar.gz" ~/.config tar with gzip compression, date substitution for filename
Text Processing
You say: "find all TODO comments in my codebase"
↓
Caro generates:
grep -rn "TODO" --include="*.{js,ts,py,rs}" . -r recursive, -n line numbers, --include for file patterns
You say: "replace all tabs with 4 spaces in python files"
↓
Caro generates:
find . -name "*.py" -exec sed -i 's/\t/ /g' {} + sed -i for in-place edit, \t matches tab, g for global replace
You say: "extract all email addresses from a file"
↓
Caro generates:
grep -oE "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}" file.txt -o output only match, -E extended regex for email pattern
You say: "show only lines that changed between two files"
↓
Caro generates:
diff --color -u file1.txt file2.txt | grep -E "^[+-]" unified diff, filter to only +/- lines (changes)
You say: "remove all blank lines from a file"
↓
Caro generates:
sed -i '/^$/d' file.txt sed delete command, ^$ matches empty lines
You say: "sort a csv by the third column numerically"
↓
Caro generates:
sort -t, -k3 -n data.csv -t, sets comma delimiter, -k3 sorts by column 3, -n numeric sort
Git Operations
You say: "show commits from last week by me"
↓

↓
Caro generates:
git bisect start HEAD v1.0 && git bisect run ./test.sh binary search between HEAD and v1.0, auto-run test script
You say: "undo my last commit but keep changes"
↓
Caro generates:
git reset --soft HEAD~1 --soft keeps changes staged, HEAD~1 is previous commit
You say: "see what changed in a file over time"

Caro generates:
git branch -a --contains <commit-hash> -a shows all branches (local+remote), --contains filters
You say: "clean up old branches that are merged"
↓
Caro generates:
git branch --merged | grep -v "\*\|main\|master" | xargs -n 1 git branch -d list merged, exclude current/main, delete each
Process Management
You say: "kill the process using port 3000"
↓
Caro generates:
lsof -ti:3000 | xargs kill -9 lsof -t outputs PID only, -i:3000 filters by port
You say: "show what's using the most memory"
↓
Caro generates:
ps aux --sort=-%mem | head -10 ps with all users, sort by memory descending, top 10
You say: "run this command in background and log output"

Caro generates:
nohup ./script.sh > output.log 2>&1 & nohup survives logout, 2>&1 redirects stderr to stdout
You say: "watch a command run every 2 seconds"
↓
Caro generates:
watch -n 2 "kubectl get pods" watch repeats command, -n 2 sets interval

Learn Commands, Don't Just Copy Them
Caro breaks down complex commands so you understand each part
Command:
find . -name "*.log" -mtime +7 -delete find The find command - searches for files . Start searching from current directory -name "*.log" Match files ending in .log -mtime +7 Modified more than 7 days ago -delete Delete matched files (careful!) The -delete flag is destructive. Always test with -print first.
Test first:
find . -name "*.log" -mtime +7 -print Command:
tar -czvf backup.tar.gz ./src tar Tape archive utility - bundles files -c Create a new archive -z Compress with gzip -v Verbose - show files being processed -f backup.tar.gz Output filename ./src Directory to archive Use -tzf to list contents without extracting
Command:
grep -rn --include="*.py" "import os" . grep Global Regular Expression Print - search text -r Recursive - search subdirectories -n Show line numbers --include="*.py" Only search Python files "import os" Pattern to search for . Start from current directory Use -i for case-insensitive search
Command:
ps aux | grep node | grep -v grep | awk '{print $2}' | xargs kill ps aux List all processes with details | grep node Filter to lines containing "node" | grep -v grep Exclude the grep process itself | awk '{print $2}' Extract second column (PID) | xargs kill Pass PIDs to kill command This is a common pattern. Caro can simplify it to: pgrep -f node | xargs kill
Command:
curl -X POST -H "Content-Type: application/json" -d '{"key":"value"}' https://api.example.com/endpoint curl Client URL - transfer data to/from server -X POST HTTP method (default is GET) -H "..." Add HTTP header -d '{"key":"value"}' Request body data https://... Target URL Use -v for verbose output to debug requests
Mistakes Caro Helps You Avoid
Learn from common pitfalls
Common mistake
rm -rf * Better approach
rm -rf ./* Without ./, if run from wrong directory, can delete unexpected files
Common mistake
chmod 777 file Better approach
chmod 755 file 777 gives everyone write access. 755 is usually sufficient.
Common mistake
cat file | grep pattern Better approach
grep pattern file Useless use of cat. grep can read files directly.
Common mistake
ps aux | grep pattern | awk '{print $2}' Better approach
pgrep -f pattern pgrep is designed for this exact task.
Common mistake
find . -name *.txt Better approach
find . -name "*.txt" Unquoted * gets expanded by shell before find sees it.
Common mistake
curl url | sudo bash Better approach
curl url -o script.sh && cat script.sh && sudo bash script.sh Always inspect scripts before running with sudo.
Caro vs. Your Current Workflow
Time spent getting commands to work
| Task | With Caro | Google/Stack Overflow | Man Pages |
|---|---|---|---|
| Find large files | 2s Describe intent | 2-5min Search, read, copy, adapt | 5-10min Read pages of documentation |
| Complex pipe chain | 3s One natural description | 5-10min Multiple searches, combine | 15+min Learn each tool separately |
| Platform-specific syntax | 2s Caro detects platform | 5min Find platform-specific answer | 10min Cross-reference BSD vs GNU |
The difference: Caro learns your context. It knows your OS, shell, and current directory.
Google gives generic answers. Man pages give exhaustive documentation. Caro gives you what you need, now.

"I used to dread the terminal. Now I actually enjoy figuring out complex file operations.
Caro's explanations turned confusion into curiosity."
"Even after 10 years, I still forget grep flags. Caro is faster than my muscle memory
for anything beyond basic searches."
"The safety warnings have saved me twice already. Once from deleting my ~/.ssh directory,
once from chmod 777 on my whole project."
