Linux Thursday
Use tmux to manage sessions.
Detach with Ctrl+B, D, reattach with tmux attach.
This keeps processes running even after SSH disconnections.
Try tmux new-session -s mysession for named sessions.
Use tmux ls to list all sessions and tmux kill-session -t mysession to end them cleanly.

File Permissions:
Ever wonder what those weird letters and dashes mean when you run ls -l in your terminal?
drwxr-xr-x is a permission string. What's it mean?:
d = directory ( - for a file)
rwx = owner perms (read, write, execute)
r-x = group perms (read, execute)
r-x = other perms (read, execute)

Today's Thursday tiny Linux tip: grep -r "text" /path searches recursively for "text" in files under /path. Super handy for hunting configs or lost code! Want case-insensitive? Add -i.

Terminal Thursday:
Now how do we create new directories, copy stuff, move stuff and remove stuff we dont want?
Like this!:
1: "mkdir" makes a new directory
2: "rm" deletes files (be careful with this one!)
3: "cp" copies files
4: "mv" moves or renames files
