simple bash script to increment the version number of the format major.minor.build

version.sh

#!/bin/bash

version="$1"
major=0
minor=0
build=0

# break down the version number into it's components
regex="([0-9]+).([0-9]+).([0-9]+)"
if [[ $version =~ $regex ]]; then
  major="${BASH_REMATCH[1]}"
  minor="${BASH_REMATCH[2]}"
  build="${BASH_REMATCH[3]}"
fi

# check paramater to see which number to increment
if [[ "$2" == "feature" ]]; then
  minor=$(echo $minor + 1 | bc)
elif [[ "$2" == "bug" ]]; then
  build=$(echo $build + 1 | bc)
elif [[ "$2" == "major" ]]; then
  major=$(echo $major+1 | bc)
else
  echo "usage: ./version.sh version_number [major/feature/bug]"

Thks.
You save me time !
i have adapted your's script for my needs https://github.com/Derioss/increment_versions.sh

I love it!
Simple and understandable.

I have copied exact code to run in my script inside a jenkins job. I have tested it on my local machine it worked but I have spent lot of time on thia and still get working on jenkins server. I get [[: not found

This code is for bash.

[[ only bash and same for this synthax "${BASH_REMATCH[1]} (Shell Parameter Expansion).

I think your's jenkins server use sh.

type bash on your's jenkins execution env, if exist, use bash version.sh

(or use maven release :) )

I missed to mention where the error was. It was if condition 【【

Okay., but when major or minor version increment, next point should be sweep to zero. Like 1.2.4 minor ---- > 1.3.0
