Nautilus, also known as “Files”, is the default file manager of the GNOME desktop environment. In a previous tutorial we saw how to create and call custom scripts from the Nautilus context-menu: this feature can be really useful but is somehow limited. By installing the nautilus-python package in our favorite Linux distribution, and writing just few lines of Python code, we can overcome such limitations and create proper Nautilus extensions.
hosts.deny format and example on Linux
The hosts.deny file can be used on a Linux system to deny connection attempts from one or more IP addresses, hostnames, or domains. It can work with any TCP wrapped service on your system. The hosts.deny file is used in conjunction with hosts.allow to determine whether a connection attempt gets accepted or denied.
hosts.allow format and example on Linux
A Linux system can utilize the hosts.allow file to specify which IP addresses, hostnames, or domains are permitted to connect to it. This works specifically for TCP wrapped services. The hosts.allow file is used in conjunction with hosts.deny to determine whether a connection attempt gets accepted or denied.
Alias example accepting arguments and parameters on Linux
Creating an alias is a good way to make commands easier to remember and quicker to type. In case you want to extend the functionality of your aliases even further, it is possible to have them accept arguments and parameters. This gives users the ability to execute complex and lengthy commands in only a few keystrokes on the command line.
How to remove dangling and unused Docker images
