I wrote SysUpdate because I kept forgetting which package manager a distro used when jumping between systems.

The tool detects the distro and updates all available package managers automatically (apt, dnf, pacman, zypper, etc).

It’s a simple Bash tool and should work on most distributions.

Tested on: Arch, Fedora, Ubuntu, Debian, Linux Mint, OpenSUSE Tumbleweed.

Feedback or distro edge cases are welcome.
