Why invoke Thread.currentThread.interrupt() in a catch InterruptException block?
...eceive a
ClosedByInterruptException.
If this thread is blocked in a Selector then the thread's interrupt
status will be set and it will return immediately from the selection
operation.
If none of the previous conditions hold then this thread's interrupt
status will be set.
So, if...

I hope somebody else upvotes this as well. Thread.sleep() might fit the code in the OP best, but it's a rather amateur reinvention of the wheel. Professional software engineers will use tried and trusted API, such as TimerTask. ScheduledExecutorService is even better, though...

JavaScript sleep/wait before continuing [duplicate]
I have a JavaScript code that I need to add a sleep/wait function to. The code I am running is already in a function, eg:

How can I wait In Node.js (JavaScript)? l need to pause for a period of time
...it syntax.
For example:
async function init() {
console.log(1);
await sleep(1000);
console.log(2);
}
function sleep(ms) {
return new Promise((resolve) => {
setTimeout(resolve, ms);
});
}
For using async/await out of the box without installing and plugins, you have to use node...
While loop to test if a file exists in bash
... if the file actually exists by adding:
while [ ! -f /tmp/list.txt ]
do
sleep 2 # or less like 0.2
done
ls -l /tmp/list.txt
You might also make sure that you're using a Bash (or related) shell by typing 'echo $SHELL'. I think that CSH and TCSH use a slightly different semantic for this loop.

What's the best way to send a signal to all members of a process group?
