Repeat a command until stopped

In this case it runs the command 'curl localhost:3000/site/sha' waiting the amount of time in sleep, ie: 1 second between runs, appending each run to the console.

This works well for any command where the output is less than your line width

This is unlike watch, because watch always clears the display.

Watch for blocked NGINX processes for tuning purposes

This command counts the number of blocked NGINX processes every 2 seconds and shows the last 22 measurements

You should have at least the number of cpu's in a non-blocked state.

The command up to the first ; truncates the log file.
