Yes, in Bash, you can check whether the -e option (which causes the script to exit immediately if any command exits with a non-zero status) is set by examining the current shell options. Here are a few ways to do it:

---

1. Using set +o or set -o

You can check the current state of the -e option (also known as errexit) using the following command:

bash
Copy
set +o | grep errexit

• If errexit is off, it will appear as errexit off.
• If errexit is on, it will appear as errexit on.

Alternatively, you can use:

bash
Copy
set -o | grep errexit

---

2. Using $-

The special variable $- contains the current set of options for the shell. You can check if e is present in this string:

bash
Copy
echo $- | grep -q 'e' && echo "set -e is ON" || echo "set -e is OFF"

• If set -e is enabled, the output will include e in the string (e.g., himBHe).
• If set -e is disabled, the output will not include e.

3. Using shopt (for Bash-specific options)

While shopt is typically used for Bash-specific options, set -e is a standard shell option, so the above methods are more direct.
