The zip and unzip commands are separate programs, and the one that packs your files returns exit code 0 whether or not it stored anything. That is how you can run zip plain.zip project, read the single line adding: project/ (stored 0%), and finish with an archive that holds no files. I ran the whole

nc is three programs sharing one name, and the option table you find usually belongs to the wrong one. On Ubuntu and Debian the nc in your PATH is netcat-openbsd, which dropped the flags that netcat-traditional and Nmap’s ncat kept, so a line copied from a guide about either of those fails the moment you

I tested the group-based and file-based ways to add a user to sudoers on a current Debian-family system, including syntax validation with visudo and permission checks with sudo -l. Use the sudo group for a normal administrator, and use a sudoers.d rule when you need narrower or separately managed access. Choose the method that matches

Vim separates typing from commands and rewards faster navigation once you learn its modes. The commands below match GNU nano 7.2 and Vim 9.1 on Ubuntu. What changes when you press a key?

Ubuntu gives you the mainstream GNOME desktop, while Lubuntu gives older or modest hardware a lighter LXQt desktop with the same Ubuntu base. For a current installation, start with the official Ubuntu Desktop download or Lubuntu’s download page and verify

Scripts run my automation on every Linux box I maintain, and the first launch often stops on a message that looks fatal but isn’t. The execute bit is missing, or the shell can’t find the file, or the script expects a different interpreter. Each launch path below comes with tested commands and the exit code

I paired my Android phone with my Linux desktop over KDE Connect and ran every step below against current documentation and packages. You get a working phone to desktop link for files, notifications, media control, and remote commands, plus the two fixes that solve most failed pairings. KDE Connect joins your phone and your computer
