A simple webserver for calling external commands and returning the result.
A webserver is started, and can receive commands that will be run in a shell. The body of the POST request should use JSON to specify the command to be run, with optional arguments. For example, to run:
ls -l test/*
give:
{"command":"ls", "args":["-l", "test/*"]}
An artificial delay is introduced by calling sleep(5) to sleep for 5 seconds.
Several commands can be processed in parallel. If the server is stopped with ctrl-c when running, it will send replies back for outstanding requests before terminating.
Check out the code from GitHub:

cd tzeract
Create and activate a virtual environment:
python3 -m venv env
. env/bin/activate
Install dependencies (requests and pytest):
pip install -r requirements.txt
pytest test_tzeract_server.py
# Start the web server by running:
uvicorn tzeract_server:app --port 8080
# Examples of usage by calling it using curl:
# List files in the directory:
curl -X POST http://localhost:8080/execute-command -H "Content-Type: application/json" -d '{"command":"ls"}'
# List files in the directory (with the -l flag):
curl -X POST http://localhost:8080/execute-command -H "Content-Type: application/json" -d '{"command":"ls", "args":["-l"]}'
# Create a directory called test:
curl -X POST http://localhost:8080/execute-command -H "Content-Type: application/json" -d '{"command":"mkdir", "args":["test"]}'
# Create a file in the directory using touch:
curl -X POST http://localhost:8080/execute-command -H "Content-Type: application/json" -d '{"command":"touch", "args":["test/file3.txt"]}'
# List files in the directory using wildcard:
curl -X POST http://localhost:8080/execute-command -H "Content-Type: application/json" -d '{"command":"ls", "args":["-l", "test/*3.txt"]}'
# External command that doesn't exits (lsx):
curl -X POST http://localhost:8080/execute-command -H "Content-Type: application/json" -d '{"command":"lsx", "args":["-l", "test/*3.txt"]}'
# Faulty URL:
curl -X POST http://localhost:8080/execute-commandXXX -H "Content-Type: application/json" -d '{"command":"ls"}'
