Uncommon Linux Commands

This is a collection of linux commands that have been helpful to me but mostly not used often enough to just remember them off the top of my head. Some are definitely better documented than others...

Active Directory / SSSD / Samba

# various methods to join and remove from AD based on OS version and AD settings
kinit admin@CORP.DOMAIN.COM
net ads join -v -k -U admin@CORP.DOMAIN.COM createcomputer="/ORG/Servers/LinuxServers"

Read lines from a process using Python

This is a quick example how to read stdin / stderr lines from a process and capture/display in a non-blocking way

In this example I'm running a FastAPI app using uvicorn. Change the commands in the subprocess.Popen line to suit your own usage.

This example uses threading and queues to avoid blocking the main process. It has also been updated to allow a clean exit when ctrl-C is pressed, and still collect all the output
