DevOps & Platform

Commands That Work
Everywhere, First Time

Stop fighting BSD vs GNU differences. Caro detects your target platform and generates POSIX-compliant commands that work on Mac, Linux, and in CI pipelines—first time, every time.

Jobs Caro Does for DevOps

What you hire Caro to do

Cross-Platform Command Generation

Pain: 4/5 Weekly

Generate commands that work on Mac, Linux, and BSD without modification.

Trigger: Writing CI pipeline or SSHing to different OS

Safe Automation Scripts

Pain: 3/5 Weekly

Generate multi-command sequences validated for safety before execution.

Trigger: Creating deployment or maintenance scripts

Natural Language Translation

Pain: 3/5 Daily

Describe what you want, get the exact command syntax instantly.

Trigger: Can't remember the exact flags for a command

The BSD vs GNU Problem

Commands you write on Mac break on Linux servers

Task	macOS (BSD)	Linux (GNU)	Gotcha
Find files modified in last hour	`find . -mtime -1h -type f`	`find . -mmin -60 -type f`	BSD find uses -mtime -1h, GNU find uses -mmin
Sort by column numerically	`sort -t, -k2 -n`	`sort -t, -k2,2 -n`	BSD sort doesn't need field end specifier
Extended regex in sed	`sed -E 's/pattern/replace/'`	`sed -r 's/pattern/replace/'`	-E (BSD) vs -r (GNU) for extended regex
Get file modification time	`stat -f %m file.txt`	`stat -c %Y file.txt`	Completely different format flags
Watch command output	`watch is not built-in`	`watch -n 1 command`	macOS needs brew install watch
Check listening ports	`lsof -i -P \| grep LISTEN`	`ss -tlnp`	Different tools for same task

How Caro Solves This

Your Mac

$ caro "find files changed in last hour"

Caro (macOS detected):

find . -mtime -1h -type f

↓

For Linux Server

$ caro --target linux "find files changed in last hour"

Caro (Linux target):

find . -mmin -60 -type f

Automation Script Examples

Common DevOps tasks, generated and validated

CI/CD Pipeline Health Check

Cross-platform

Check deployment status across services

$ caro "check if all kubernetes deployments are ready in production"

→ kubectl get deployments -n production -o jsonpath='{range .items[*]}{.metadata.name}: {.status.readyReplicas}/{.status.replicas}{"\n"}{end}'

Log Aggregation

POSIX compliant

Find error patterns across multiple log files

$ caro "find all ERROR lines in logs from the last 24 hours"

→ find /var/log -name "*.log" -mtime -1 -exec grep -l "ERROR" {} \; | xargs grep "ERROR" | tail -100

Docker Cleanup

Docker

Remove unused Docker resources safely

$ caro "clean up docker images and volumes that are not being used"

→ docker system prune -af --volumes

This removes ALL unused images, containers, and volumes

Safer: docker image prune -a --filter "until=168h"

Service Dependency Check

Linux (systemd)

Verify all required services are running

$ caro "check if redis, postgres, and nginx are running"

→ for svc in redis postgresql nginx; do systemctl is-active --quiet $svc && echo "$svc: running" || echo "$svc: stopped"; done

Certificate Expiry Check

Linux

Find certificates expiring soon

$ caro "show SSL certificates expiring in the next 30 days"

→ find /etc/ssl/certs -name "*.pem" -exec openssl x509 -enddate -noout -in {} \; 2>/dev/null | grep -i "notafter"

Terraform State Check

Terraform

List resources in Terraform state

$ caro "show all AWS EC2 instances in terraform state"

→ terraform state list | grep aws_instance

Natural Language → Commands

Stop Googling. Just describe what you want.

"find large files"

↓

find . -type f -size +100M -exec ls -lh {} \;

"show disk usage by directory"

↓

du -sh */ | sort -rh | head -10

"list all open ports"

↓

ss -tlnp

"find processes using most memory"

↓

ps aux --sort=-%mem | head -10

"compress old logs"

↓

find /var/log -name "*.log" -mtime +7 -exec gzip {} \;

"show git branches by last commit"

↓

git branch -a --sort=-committerdate | head -20

"find duplicate files"

↓

find . -type f -exec md5sum {} \; | sort | uniq -d -w32

"monitor file changes"

↓

inotifywait -m -r -e modify,create,delete .

"check DNS resolution"

↓

dig +short example.com && nslookup example.com

"show network connections"

↓

netstat -ant | awk '{print $6}' | sort | uniq -c | sort -rn

"find files changed today"

↓

find . -type f -mtime 0

"list docker container IPs"

↓

docker inspect -f '{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -q)

Your Turn

Install Caro and try:

caro "show me what's using port 8080" caro "find all yaml files with 'production' in them" caro "show docker containers by memory usage"

CI/CD Pipeline Integration

Commands that work in GitHub Actions, GitLab CI, Jenkins

Use POSIX Mode

caro --posix "your task"

Forces POSIX-compliant output that works in any sh-compatible environment.

Target Specific Platform

caro --target linux "your task"

Generate commands for your CI runner's OS, not your dev machine.

JSON Output for Scripts

caro --output json "your task"

Machine-readable output for integration with other tools.
