Ysx | 8 years ago | on: How “Exit Traps” Can Make Bash Scripts More Robust and Reliable

Beware that you can only have one EXIT handler. I've used this in the past figuring it's analogous to Go's `defer`, but unfortunately not.

e.g this script:

    #!/bin/bash
    trap 'echo Handler 1' EXIT
    trap 'echo Handler 2' EXIT
Will only call 'Handler 2' on exit.

Google are sensitive about the spam potential, to the point where they proxy beacon URL resolution through their servers.

Not sure what I'm missing here?

    $ docker run -it ubuntu
    # chmod 444 /bin/chmod
    # /bin/chmod
    bash: /bin/chmod: Permission denied
