After creating the file ./_generic_installer.sh with the _generic_installer.sh snippet contents bellow, change/tweak it as you would like.
Then, you can run/use it like the following, i.e., by importing/sourcing it and calling its convenience functions.
You can see all confience functions by calling the help command. Just see the first usage example sample output.

Just calling
./test.shuser@user$ ./test.sh Usage instructions, you can call this script with the following named arguments: -y to answer all questions as yes -n to answer all questions as no -h to show this help message -s number to skip the first nº instructions -v version to install the selected version from git You can call this script with the following positional arguments: 1. version to install the selected version from git 2. number to skip the first nº instructions If you are going to call the 'list_git_tags' function, these the global variables must be defined before calling the 'parse_command_line' function '${thing_name}', the target directory to save the cloned git repositories '${git_server}', the targer git repository to fetch data from And these global variables are optional for the 'list_git_tags' function '${tags_columns_width}', the minimum length of each git tags column '${branches_columns_width}', the minimum length of each git branches column These are the available global variables after calling 'parse_command_line' '${branch_or_tag}', it has the same value/saves the version command line argument '${clone_directory}', the full path to where clone the git repository Usage examples: ./test.sh ./test.sh v1.8.4 ./test.sh v1.8.4 20 ./test.sh -h ./test.sh -v v1.8.4 ./test.sh -v v1.8.4 -s 10 ./test.sh -y ./test.sh -y -s 20 ./test.sh -y -s 20 -v v1.8.4 API Documentation Function parse_command_line Validate and get all named and positional line arguments from $1 to $n. Example: parse_command_line "${@}"; Function run Run the given command, only when we are not skipping the first nº commands. Example: run ls -la; Function runalways Always run the given command, even when we are skipping the first nº commands. Example: runalways ls -la; Function runset Set a global variable value as the output of the following shell command. This outputs to the console the assigned variable contents. Example: runset myglobalvar ls -la; Function runsets Set a global variable value as the output of the following shell command. This does NOT outputs (silent assignment) to the console the assigned variable contents. Example: runsets myglobalvar ls -la; Function ask_to_run Before running a command, ask whether the command should run or skipped. Example: ask_to_run ls -la; Function list_git_tags Fetch a git repository remote tags and list them. This function does not take any parameters. Example: list_git_tags; Loading 'sshfs' versions from 'https://github.com/libfuse/sshfs'... This should take about 10 seconds...
