- Merges both scripts into a single unified housekeeping.sh - Subcommands: update, clean, omz, all (default) - New 'omz' command: runs 'omz update' with safe fallback if not installed - Unknown subcommands print usage and exit 0 - Shared utility functions defined once at top - Preserves all existing OS detection, cleanup, and reporting logic
server-scripts
Useful scripts for managing servers written in Bash. Supported OS includes Debian/Ubuntu, Alpine, Arch, RHEL/Fedora/CentOS, openSUSE, Void, and Gentoo.
In the past I was using it more for maintaining my home servers, bare metal with Docker, however when I changed to k3s, I started using it less. Now I'm using this as a collection of useful scripts that I can use when needed. Also clean.sh is still useful.
clean.sh
This script is used to clean some of the files, docker dangling images, and docker stopped/unused containers.
update.sh
Detects the running OS (Alpine, Arch, Debian/Ubuntu, RHEL/Fedora/CentOS, openSUSE, Void, Gentoo) and updates the package list only — it does not upgrade or install any packages. Useful for keeping package indexes fresh so that upgrade commands run faster later.
Run with curl | bash:
curl -sSL https://git.ivanch.me/ivanch/server-scripts/raw/branch/main/update.sh | bash
windows-backup.ps1
This PowerShell script is used to backup files from a Windows machine to a remote Samba server. It uses 7zip to create the zip file, and then sends over the network using SMB protocol.
dns-override.sh
Aggressive, best-effort DNS override script for Linux hosts with support for multiple resolver stacks (systemd-resolved, NetworkManager, resolvconf/openresolv, dhclient, systemd-networkd, and ifupdown) plus direct /etc/resolv.conf writes.
It prompts for:
- 2 required DNS servers
- 1 optional third DNS server
Validation/features:
- Accepts IPv4 and IPv6 literals
- Rejects invalid or duplicate entries
- Performs reachability checks (warn-only, does not block execution)
- Can optionally lock
/etc/resolv.confwithchattr +i
Run with curl | bash:
curl -sSL https://git.ivanch.me/ivanch/server-scripts/raw/branch/main/dns-override.sh | bash
Important notes:
- Requires interactive TTY input (prompts are read from
/dev/tty) - Requires root privileges (
sudois used/re-execed when possible) - Script is intentionally aggressive and may restart/reload network services
- On heavily managed systems (custom agents, immutable images, enterprise policy), behavior is still best-effort
