I installed Mongoose OS using the following command on Debian 9.5.0:

curl -fsSL https://mongoose-os.com/downloads/mos/install.sh | /bin/bash

How do I safely uninstall this software?

  • It's really not recommendable to do curl | sh like commands, especially not as root. The only limits to what a script executed liked that can do, is what the user you excuted it as can do, and there's no general way to undo what it does. A quick look at this script suggests to me that it only downloads one file and puts it in ~/.mos so deleting that should be okay (but it's nearly 2 in the night here - having an issue at work, waiting for a network guy to debug it - so I might be wrong) Sep 12, 2018 at 23:59
  • Thanks Henrick. The official site (mongoose-os.com/software.html) advised to do that. Looking for an expert advice.

To determine how to uninstall a piece of software installed in this fashion, you need to read through the script used to perform the installation and determine what it did, then undo that. Using curl | sh-style patterns means that the installation script isn’t preserved, so we need to download the current version and hope that its behaviour hasn’t changed since the installation.

In this particular case, uninstallation is straightforward, assuming defaults:

  • delete ~/.mos/bin/mos — that’s the only file added during installation;
  • if ~/.mos/bin is empty, delete it, and then if ~/.mos is empty, delete it;
  • edit ~/.bashrc or ~/.profile to remove the line adding ~/.mos/bin to the PATH.

If you specified a different DESTDIR when installing, then you’ll need to remove mos from that directory instead.
