Repository Add and Initial Setup
Adding a repo
The following adds the LEAP 42.1 Perl repo, non-interactively automatically accepting defaults (Yes to all questions) and sets the repo to auto-refresh
zypper -n ar -f http://download.opensuse.org/repositories/devel:/languages:/perl/openSUSE_Leap_42.1/ LEAP_42.1:Perl
Auto accept GPG keys
The following refreshes all repos, and automatically accepts the GPG keys for all newly added repos
zypper --gpg-auto-import-keys ref
Detect OS version and auto insert into add repo URI automatically
The following automatically detects the running openSUSE version, and installs the Perl repo example for that distro. The following does not support Tumbleweed.
VERSION=$(grep VERSION /etc/SuSE-release | sed -e 's/VERSION = //') && \ zypper ar -nf http://download.opensuse.org/repositories/devel:/languages:/perl/openSUSE_Leap_$VERSION/ openSUSE_$VERSIONIn:Perl
Tumbleweed vs all other stable openSUSE
The following can detect Tumbleweed vs all other current stable openSUSE. In the following example, if Tumbleweed is detected "net-tools-deprecated" is installed if a network setup requires consistent network interface naming across all openSUSE versions.
#!/bin/bash ID=$(grep -w ID= /etc/os-release | sed -e 's/ID=//') VERSION_ID=$(grep -w VERSION_ID= /etc/os-release | sed -e 's/VERSION_ID=//' | sed -e 's/"//g') if [ "$ID" = '"opensuse-tumbleweed"' ]; then echo Tumbleweed detected, do TW stuff zypper in net-tools-deprecated # zypper -n ar -f http://download.opensuse.org/repositories/science/openSUSE_Factory/ openSUSE_Factory:science # zypper --gpg-auto-import-keys ref else if [ "$ID" = '"opensuse-leap"' ]; then echo This must be LEAP $VERSION_ID echo Do LEAP stuff # zypper -n ar -f http://download.opensuse.org/repositories/science/openSUSE_Leap_$VERSION_ID/ openSUSE_$VERSION_ID:science # zypper --gpg-auto-import-keys ref fi fi
