Why the Command Line Still Matters
Despite advances in GUI tools, the command line remains the most efficient interface for server administration, automation, and development workflows. Remote servers accessed via SSH have no GUI — command line proficiency is non-negotiable for backend developers and DevOps engineers.
Essential File Commands
ls -la— List all files including hidden, with detailsfind . -name "*.tsx" -type f— Find files by patterngrep -r "search term" ./src— Search within filescp -r source/ dest/— Copy directories recursivelychmod 755 script.sh— Set file permissions
Process Management
ps aux lists all running processes. kill -9 PID force-terminates a process. top or htop shows a real-time process monitor. nohup command & runs a process that survives terminal closure.
Networking Commands
curl -I https://testrefy.com checks HTTP response headers. netstat -tulpn shows listening ports. ssh user@server connects to a remote server. scp file.txt user@server:/path copies files over SSH.
