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

You say: "count lines of code in all python files"

↓

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 log --author="$(git config user.name)" --since="1 week ago" --oneline

💡 filter by author and date, oneline for compact output

You say: "find which commit introduced a bug"

↓

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 log -p --follow -- path/to/file.js

💡 -p shows patches, --follow tracks renames

You say: "find all branches containing a specific commit"

↓

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

You say: "find zombie processes"

↓

Caro generates: ps aux | awk '$8=="Z" {print}'

💡 awk filters where column 8 (STAT) is Z (zombie)

You say: "run a command with timeout"

↓

Caro generates: timeout 30s ./long-running-script.sh

💡 timeout kills process after duration

Network Operations

You say: "download a file and resume if interrupted"

↓

Caro generates: curl -C - -O https://example.com/large-file.zip

💡 -C - resumes transfer, -O saves with original name

You say: "check if a website is responding"

↓

Caro generates: curl -Is https://example.com | head -1

💡 -I HEAD request only, -s silent, head -1 shows status

You say: "find my public IP address"

↓

Caro generates: curl -s ifconfig.me

💡 ifconfig.me returns your public IP as plain text

You say: "test if a port is open on a remote server"

↓

Caro generates: nc -zv example.com 443

💡 nc netcat, -z scan without sending data, -v verbose

You say: "show all listening ports"

↓

Caro generates: ss -tlnp

💡 -t TCP, -l listening, -n numeric, -p process

You say: "monitor network traffic in real time"

↓

Caro generates: sudo tcpdump -i any -n port 80

💡 -i any all interfaces, -n no DNS, port 80 filter

Docker Operations

You say: "clean up all unused docker resources"

↓

Caro generates: docker system prune -af --volumes

💡 -a all unused, -f force, --volumes includes volumes

You say: "see logs from a container that crashed"

↓

Caro generates: docker logs --tail 100 <container-id>

💡 --tail 100 shows last 100 lines

You say: "copy a file from a running container"

↓

Caro generates: docker cp <container-id>:/path/to/file ./local-copy

💡 docker cp works like regular cp but across container boundary

You say: "run a one-off command in a container"

↓

Caro generates: docker exec -it <container-id> /bin/sh

💡 -i interactive, -t allocate TTY, for shell access

You say: "show resource usage of all containers"

↓

Caro generates: docker stats --no-stream

💡 --no-stream shows single snapshot instead of live

You say: "find which image a container is using"

↓

Caro generates: docker inspect --format='{{.Config.Image}}' <container-id>

💡 --format with Go template extracts specific field

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.
