apk-upgrade

The apk-upgrade script is a convenience tool designed for Alpine Linux users to simplify the process of updating and upgrading system packages. It combines the steps of apk update, apk upgrade -s, and apk upgrade into a single interactive workflow.

Usage

Save the script to a file, for example, apk-upgrade.sh, and make it executable with chmod +x apk-upgrade.sh.

The script will:

1. Update the package index.
2. Check for and display any available upgrades.
3. Prompt for confirmation before upgrading packages.

If no upgrades are available, the script will exit without performing any changes.

# ./apk-upgrade.sh

Updating apk cache...
fetch http://dl-cdn.alpinelinux.org/alpine/v3.18/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.18/community/x86_64/APKINDEX.tar.gz
OK: 15634 distinct packages available

Checking for upgradable packages...

(1/2) Upgrading libssl (1.1.1s-r0 -> 1.1.1t-r0)
(2/2) Upgrading openssh (9.1_p1-r0 -> 9.2_p1-r0)
