How to detect if a git clone failed in a bash script

Question

How can I tell if a git clone had an error in a bash script?

git clone [email protected]:my-username/my-repo.git

If there was an error, I want to simply exit 1;

Here are some common forms. Which is the best to choose depends on what you do. You can use any subset or combination of them in a single script without it being bad style.

---

if ! failingcommand
then
    echo >&2 message
    exit 1
fi

---

failingcommand
ret=$?
if ! test "$ret" -eq 0
then
    echo >&2 "command failed with exit status $ret"
    exit 1
fi

---

failingcommand || exit "$?"

---

failingcommand || { echo >&2 "failed with $?"; exit 1; }
