10In Bash, the `$SECONDS` variable is a special variable that automatically keeps
11track of the number of seconds since the current shell or script started
12executing. It starts counting from the moment the script begins running.
13
14```bash
15#!/bin/bash
16
17# Reset the timer to zero.
18SECONDS=0
19
20# Do something.
21sleep 5
22
23# Print the time elapsed.
24echo "Time taken: $SECONDS seconds"
25```
