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