Files guides
Hands-on guides that cover Files. Every command is run and verified on a live server before it is published.
GuideUnit Files and the systemd Model
Turn a bare script into a systemd service that survives a crash, then read the systemd unit files behind it: sections, systemctl cat and drop-ins.
GuideNavigating the Filesystem
Linux filesystem navigation with cd, ls and pwd on an Ubuntu 24.04 server. Move around the directory tree and learn to read what ls -la is telling you.
GuideWorking With Files and Directories
Create and move files on Linux with mkdir, cp, mv and rm. Practise on a real project tree so copying a config or cleaning up a release becomes muscle memory.
GuideViewing and Editing Files
View files on the Linux command line with cat, less, head and tail. Read configs and logs, and watch a log grow in real time while a problem is happening.
GuideMaking the Shell Your Own
Set up bash aliases and dotfiles on an Ubuntu 24.04 server. Add shortcuts for the commands you type most and make every future login start ready to go.
