Some tweaks I made to bash-git-prompt. dynamic Python virtualenv path, new var GIT_MESSAGE, etc.

Some nice cicd bash common scripts

During CICD, we often have a large log output, it might be nice to have some common scripts to help us to format the log output, so that we can easily find the information we need.

Recently, when working with Sonar, I found that they have some scripts for such output formatting.

Github Actions: Bash shell -e -o pipefail

Bash shell in Github actions by default is run with -e -o pipefail option. The full command used by Github actions is :

shell: /usr/bin/bash --noprofile --norc -e -o pipefail {0}

Hashing files

During CI/CD processes, and particularly during CI, we frequently hash dependency files to create cache keys (referred to as key input in Github Action actions/cache and key parameter in Azure pipelines Cache@2 task). However, the default hash functions come with certain limitations like this comment. To address this, we can use the following pure Bash shell command to manually generate the hash value.
