Add the following statement to the. bashrc file in the user directory, and then execute the source. BASHRC to make it effective immediately.

Ps1= ' ${debian_chroot:+ ($debian _chroot)}\[\033[01;31m\]\[email protected]\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[ 00m\]\$ '

Escape sequence Character

In order to add a personal-style color prompt, we need to use escape sequence characters. An escape sequence character is a control command that controls the shell's execution of a particular action. an escape sequence character usually starts with ESC, is recorded as "^[" in the shell, and is sometimes recorded as 3 (because ESC is 27 in ASCII encoding and octal is recorded as 033). In order to enter an escape sequence character directly in the shell, it is generally preceded by "Ctrl + V", which is "Ctrl-v ESC".

Using the shell color

First use an example to illustrate how to implement the shell color:

Ps1= "[3[0;32;[ Email protected]:w$ 3[0m] "


The following prompt is displayed:


In the command above, "3[0;32;40m" indicates the color of the text behind it, "3" means start an escape sequence, "[" Defines the start color definition, "0" defines the default font color, and the rest of the section is defined later. "32" defines the foreground color of the text, where 32 means green; "40" Defines the background color of the text, and 40 indicates black. At the end of the string, "3[0m" is defined, and it is used to restore the default text color setting so that only a color prompt is obtained without affecting the command and the color display of its output (that is, white on black).
