try
Inspect a command's effects before modifying your live system
Try is a Linux command-line utility that lets users run a command and inspect its effects before deciding whether to commit those changes to the live system. It works by using Linux namespaces through unshare together with overlay-based filesystem techniques so that commands can execute in an isolated view of the system rather than directly modifying the host environment immediately. This makes it useful for experimenting with package installation, system changes, and other shell commands...
