Simple script to bump pkgrel of a pkg's dependents. Could be improved and simplified if Alpine Linux tools were used, but this can be used on other OS'

aport_bump_pkgrel.sh

#!/bin/bash

set -eu

if [ $# -eq 0 ]
  then
    echo 'No arguments supplied. Supply two!
    - $1 search pattern - e.g. icu-dev
    - $2 string containing name & version of the pkg to rebuild against - e.g. "icu 65.1"'
    exit 1
fi

# Find all matching input
grep -rn "$1" --include="APKBUILD" . > bump_pkgrel.txt

# Cleanup input
## Remove all content from first colon until end of line
sed -i 's/:.*$//g' bump_pkgrel.txt

## Remove all lines with ./unmaintained/
sed -i '/^.\/unmaintained.*$/d' bump_pkgrel.txt

## Sort and remove duplicates
sort -u bump_pkgrel.txt -o bump_pkgrel.txt

## Move main pkgs to the top
sed -i '/^.\/main.*$/!H;//p;$!d;g;s/\n//' bump_pkgrel.txt

# Bump pkgrel & commit
while read i; do
  echo "Currently working on: $i"
  sed -i -r 's/(.*)(^pkgrel=)([0-9]+)(.*)/echo "\1\2$((\3+1))\4"/ge' "$i"
  git add "$i"
  git commit -m "${i:2:-9}: rebuild against $2"
done < bump_pkgrel.txt

echo -e "\n\nAll done!"
