Linux Commands Training - How NOT to Use Linux GUI Utilities - Instead of Using Linux Commands
In addition to using Linux commands (the GNU Linux commands and the non-GNU Linux commands) to do Linux system administration, you can also use "point-and-click" Linux GUI utilities.
Linux Commands Training Tips: The many reasons to use Linux commands to do Linux system administration tasks, instead of using Linux GUI utilities, were described in detail earlier.
Here is a summary of the reasons NOT to Use Linux GUI Utilities:
Most Linux GUI utilities are "proprietary" and only work in a single Linux distribution - and so learning to use a Linux GUI in one Linux distro is
useless when you have to change to a different Linux distro
Linux GUI utilities require a Linux desktop on which to run and many Linux server systems don't have a Linux desktop (and the Linux desktop software components required for a Linux desktop) installed
It takes several "point-and click" menu steps to start a Linux GUI utility
And then it also takes a long time for a Linux GUI utility to be up and ready to be used (especially on old systems)
You need to do a lot of "point-and-click" steps in a GUI utility to do a task that can quickly be done in a few seconds by running a Linux command
You can't automate (and automatically process) the Linux GUI utility steps that are required to do a Linux task - but you can automate the Linux commands required to do a task by creating a Linux "executable" script file.
Linux Commands Training Tips: A Linux script is a "text file" that contains a series of Linux commands. The Linux script file is made "executable" so that it can be run like any other Linux command at the Linux command line prompt.
Typing in the name of the Linux "executable" script file and pressing Enter causes all of the Linux commands in the script file to be run, one after the other.
The Steps to Create and Run a Linux Script
It's easy to create and run a Linux script, just: 1. run a Linux text editor, 2. create a text file (by giving it a name), 3. put the Linux commands you need to run in the text file, 4. run the chmod command and make the Linux text file "executable" and this makes the Linux text file a Linux script file that can be run like a Linux command.
To run the Linux script (in the same way as you run a Linux command), just: type in the name of the Linux script file and press Enter - and then all the commands in the file will be executed, one after the other.
Linux scripts are an extremely powerful (and relatively easy) way to "program" a series of Linux commands and automate a commonly performed Linux task - and save yourself a ton of time!
Linux GUI Utilities vs. Linux Commands - Don't Waste Your Time Learning Linux GUI Utilities
As with learning (non-GNU) Linux commands, don't your waste time learning "proprietary" GUI Linux utilities - that will only work in one Linux distribution - unless you absolutely have to (for some strange reason).
Why learn how to use proprietary, slow, and cumbersome Linux GUI utilities that will only work in one Linux distro you may never use that Linux distribution again?
