In a Bash script that uses `getopts` for option parsing, you can exit immediately by using the `exit` command when an option is encountered that should trigger an immediate exit. Here's an example:
```bash
while getopts "abc:" opt; do
case $opt in
a)
# Process option 'a'
;;
b)
# Process option 'b'
;;
c)
# Process option 'c' with an argument
arg="$OPTARG"
;;
\?)
# Invalid option
echo "Invalid option: -$OPTARG" >&2
exit 1
;;
esac
done
# You can add additional logic here as needed
# For example, if option 'b' was given, exit immediately
if [ "$b_option_used" ]; then
exit 0
fi
# Rest of your script
```
In this example, if you encounter a condition that should trigger an immediate exit, you can use the `exit` command to exit the script with a specific exit code. Be sure to set the exit code accordingly (e.g., `exit 0` for a successful exit or another value for an error exit).
Remember to adapt this example to your specific script and the conditions under which you want to exit immediately.
