Graphical desktop environments like GNOME, KDE, LXDE, Unity, etc. all include terminal emulators as standard equipment. We can think of this as a safety feature because, if the desktop environment suffers from some lack of functionality (and they all do), we can still access the shell and actually get stuff done. Modern terminal emulators are quite flexible and can be configured in many ways: gnome-terminal preferences dialog Size Terminal emulators display a window that can be adjusted to any size from the sublime to the ridiculous. Many terminals allow configuration of a default size. The “normal” size for a terminal is 80 columns by 24 rows. These dimensions were inherited from the size of common hardware terminals, which, in turn, were influenced by the format of IBM punch cards (80 columns by 12 rows). Some applications expect 80 by 24 to be the minimum size, and will not display properly when the size is smaller. Making the terminal larger, on the other hand, is preferable in most situations, particularly when it comes to terminal height. 80 columns is a good width for reading text, but having additional height provides us with more context when working at the command line.Īnother common width is 132 columns, derived from the width of wide fan-fold computer paper. Though this is too wide for comfortable reading of straight text (for example, a man page), it’s fine for other purposes, such as viewing log files. The 80-column default width has implications for the shell scripts and other text-based programs we write. We should format our printed output to fit within the limits of an 80-character line for best effect. TabsĪ single terminal window with the ability to contain several different shell sessions is a valuable feature found in most modern terminal emulators. This is accomplished through the use of tabs. Tabs are a fairly recent addition to terminal emulators, first appearing around 2003 in both GNOME’s gnome-terminal and KDE’s konsole. ProfilesĪnother feature found in some modern terminals is multiple configuration profiles. With this feature, we can have separate configurations for different tasks.
