3) Color We will play with PS1 prompt's color. Please make your PS1 prompt: a text format: bold (See Linux/Unix Color Code Table below) b. text color: 36 c. back round color: optional, you may choose one yourself or leave it as the default background color, Beains, don't put any value for background color.) Either of the following color syntax works in Linux system: le Seelessados \/\033[ScoLeRada Ser: Start color scheme.m: End color scheme [\033: Start color scheme. ]: End color scheme ] $selercedes could be in the format of x or six or X x. one of three categories Ex: \[36m y Color pair to use (82) two of the three categories (see Linux/Unix Color Code table below) [order doesn't matter] EX: Ve[1; 36m XYZ All three categories [order doesn't matter) EX le [44;1; 36m IMPORTANT. Please use els or \[\ ] to stop your color scheme, so that you only set color to PS1 but not the entire terminal or other elements in the terminal Text Foreground (text) color Background color Format 0: Normal or back to normal 30: Black 40: Black 41 Red 31: Red 1: Bold 4: Underlined 32: Green 44: Blue 45: Purple 46: Cyan

Linux command to edit PS1:

export PS1="\[\033[01;36;41m\]\u@\h \w\$\[\033[00;37;40m\] "

Understanding the above command:

export PS1="\[\033[01;36;41m\]\u@\h \w\$\[\033[00;37;40m\] "

\[\033 - starts a color scheme
[01;36;41 - sets font to bold (01), foreground color to Cyan (36), and background color to Red (41)
m\] - stops the color scheme

Now, since we only want to change color of the prompt and not the whole terminal, therefore, we again
need to start another color scheme after '$' of the prompt.

[00;37;40 - sets font back to normal (00), foreground color to White (37), and background color to Black (40)

Prompt before editing PS1:

shubham@DESKTOP-RBUJ4KN: ~ X shubham@DESKTOP - RBUJ4KN: $ echo $PS1 N[ \e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\] \u@\h\ [\®33 [00m\]:\[\033[01;34m\ ] \w\ [\@33 [00m\] \$ shubham@DESKTOP - RBUJ4KN:

Prompt after editing PS1:

shubham@DESKTOP-RBUJ4KN: shubham@DESKTOP-RBUJ4KN: $ export PS1="\[\€33[01;36;41m\] \u@\h_\w\$\[\033 [00; 37 ; 40m\ shubham@DESKTOP - RBUJ4KN ~ echo $PS1 N[\€33[01;36;41m\]\u@\h_ \w$\[\033[00; 37 ; 40m\] shubham@DESKTOP - RBUJ4KN ~$
