37 INSANE Linux Commands you NEED to Know in 2025

About this video

Chuck races through 37 Linux commands presented mostly as faster, friendlier replacements for classic tools, demonstrated largely on a remote Hostinger VPS. Disk and system inspection covers NCDU and Duff for space, lshw for hardware, Glances, iotop and dstat for live stats, stat for file detail, and systemd-analyze blame/critical-chain for slow boots. Finding and navigating gets ripgrep for fast log and code search, fd instead of find, fzf for fuzzy filtering of lists and history, Ranger as a terminal file manager, Zoxide instead of cd, and Exa instead of ls. Remote and networking tools include Mosh, which keeps an SSH-like session alive while roaming between Wi-Fi and cellular (installed on both ends), MTR combining ping and traceroute hop by hop, dog for DNS, TermShark as a terminal UI for TShark, lsof -i to find which process owns a port, and ipcalc for subnet math. The back half covers Wormhole for encrypted peer-to-peer file transfer, procs, Lazydocker, rsync’s delta-only syncing, shred for real deletion, moreutils, unp, jq, TaskWarrior, Asciinema session recording, and AI help from Fabric and a local Ollama agent that drafts commands on request.

Key takeaways

• Modern replacements beat the classics on speed and usability: ripgrep over grep, fd over find, Exa over ls, Zoxide over cd, procs over ps, and Duff over df.
• Mosh keeps a remote session open while roaming between networks, unlike ordinary SSH, but it must be installed on both the client and the server.
• Diagnose before guessing: NCDU finds what eats disk space, systemd-analyze blame names slow boot services, iotop/dstat/Glances expose live bottlenecks, and lsof -i shows which process owns a port.
• rsync syncs only differences and can resume broken transfers over SSH; rm merely unlinks a file, while shred overwrites it multiple times before deletion to thwart recovery.
• AI can be piped into the shell workflow: Fabric can summarize command history or analyze logs, and a custom local Ollama agent can generate commands on request.
