Good practices

Use sh

If you do not need bash features, then use sh, it is installed on every UNIX-like system.

1

#!/bin/sh

Exit on failure

Shell scripts continue even if a commend returns error. To fail right away use:

1

set -e

Trap C-c

Catch Control-c and exit.

1

trap 'exit 128' INT

Use script directory

Assume we are executing a script from directory /Admin, where / is the root of a given project directory.

1
2

script_path="${0}"
script_root="$(dirname "${script_path}")"

We can use ${script_root} to call other scripts form the Admin directory, but we can also use it to relate to the /.

1
2
3

project_root="$(realpath "${script_root}/../")"
echo "[INFO] Entering directory: ${project_root}"
cd "${project_root}"

So with above we can run commands form / (repository root). Like for example make and other:

1
2

make
python3 ./Admin/serve_1.py

Even better

Use Python for repository maintenance scripts.

from os import chdir
from os import path

from subprocess import run
from sys import argv

script_path = path.realpath(__file__)
script_root = path.dirname(script_path)
project_root = path.realpath(path.join(script_root, ".."))

print(f" * Entering directory: {project_root}")
chdir(project_root)

leftover_args = argv[1::]
command_arguments = ["make"] + leftover_args

cmd_string = " ".join(command_arguments)
print(f" * Executing command: {cmd_string}")
run(command_arguments, check=True)
