wait

wait pauses a script until a background job finishes, or until all background jobs finish if called with no arguments. wait $pid waits for one specific job and captures its exit status. This is essential for coordinating multiple background tasks before moving on.

Note: Call wait with no arguments to pause until *every* background job the script started has completed.

Example: wait

bash

#!/bin/bash
sleep 1 &
sleep 1 &

echo "Waiting for all background jobs..."
wait
echo "All background jobs finished"
