Both commands sound like they do the same thing but they are used in very different ways
Sleep
Stops script execution for a specified amount of time in seconds e.g sleep 30 will stop the script for 30 seconds before continuing.
Wait
Wait command pauses the script just like sleep but it waits for a process to complete regardless if it was success or failure e.g wait 123456 will wait for the process 123456 (PID).
