0. About thread synchronization(1) Why do I need to sync multithreading?thread synchronization is to allow multiple running threads to work together in a good way to allow multithreading to properly occupy released resources as required. We use the

threading all objects in the module: Thread : represents the execution object lock of one thread: Lock originated from Object Rlock: Can be reentrant to lock object so that a single thread can get the acquired lock again (recursive lock) Condition:

Nested loops (inner loop): A loop statement can use any type of command in a loop, including other loop commandsExample 1:#!/bin/bashfor ((a = 1; a Doecho "Starting loop $a"for ((b = 1; b Doecho "Inside loop $b"DoneDone[Email protected]
