  • Using ANSI Color Codes General Configuration of the Shell

Since a few years he keeps very busy with In an ANSI compatible terminal (like xterm, rxvt, konsole ...) text may Linux, he also takes part in be shown in colors different from black/white. This article will a number of Open Source demonstrate text in bold or in color. Projects. _________________ _________________ _________________ Translated to English by: Jürgen Pohl <sept.sapins(at)verizon.net> General In real life every Linux user gets to face the Bash. At first glance that looks very boring, but there are many possibilities to give one’s shell the personal touch. Colored enhancement of the shell prompt make the shell unique as well as better legible. In my description I will refer to the Bash shell. The escape sequences may differ between terminals, for this text I am using an ANSI terminal. Configuration of the Shell Setting of shell colors happens in the personal configuration file of the bash ~/.bashrc or in the global configuration file /etc/bashrc. The appearance of the prompt is being set with the PS1 variable in bashrc. Generally, the entry should look like this: ~/.bashrc: PS1="\s-\v\$ " \s stands for the name of the shell and -\v for its version. At the end of the prompt we are placing a $. Since this gets a bit boring, the following entry - which is default in most Linux distributions - may be used: ~/.bashrc: PS1="\u@\h \w \$ " This stands for user@ current_directory $, which is the normal shell prompt most Linux users are familiar with.
