LinuxCommand.org: Midnight Commander

At the beginning of chapter 4 in TLCL there is a discussion of GUI-based file managers versus the traditional command line tools for file manipulation such as cp, mv, and rm. While many common file manipulations are easily done with a graphical file manager, the command line tools provide additional power and flexibility.

In this adventure we will look at Midnight Commander, a character-based directory browser and file manager that bridges the two worlds of the familiar graphical file manager and the common command line tools.

The design of Midnight Commander is based on a common concept in file managers: dual directory panes where the listings of two directories are shown at the same time. The idea is that files are moved or copied from the directory shown in one pane to the directory shown in the other. Midnight Commander can do this, and much, much more.

How to Handle App/OS Freezes in Linux

Linux-based operating systems are deemed to be more stable than other operating systems. Testimony to this is the fact that Linux powers over 95% of supercomputers in the world. However, stability and performance doesn’t mean that Linux systems don’t experience app or OS freezes.

There could be many different types of freezes such as situations where one or more applications freeze, the mouse stops responding along with applications, and finally, where everything (including the keyboard) freezes. In this article we will discuss in detail the various solutions available for each case and in what order you should apply them.
