Linux: Ubuntu 14.04

Picture of the entire operation code process and final display result

Input> echo $ PS1

Display: as shown in Figure

Enter in the personal user folder

Enter gedit ~ /. Bashrc

Modify these lines of code

If ["$ color_prompt" = yes]; then

PS1 = ....

Else

PS1 =...

Fi

Unset color_prompt force_color_prompt

# If this is an xterm set the title to user @ host: dir

Reset:

# If ["$ color_prompt" = yes]; then

# PS1 = '$ .......... \ [\ 033 [01; 32m \] \ u @ \ h \ [\ 033 [00m \]: \ [\ 033 [01; 34m \] \ w \ [\ 033 [00m \] \ $'

# Else

# PS1 = '$... \ u @ \ h: \ w \ $'

# Fi

Unset color_prompt force_color_prompt

# If this is an xterm set the title to user @ host: dir

Add the following line at the end of the file:

(The next line is) PS1 = '$ ................... \ 033 [01; 31m \] \ u \ [\ 033 [00m \] @ \ h: \ w \ $'

Save and exit. Then, click "source", that is, enter> source ~ /. Bashrc

The path/root in the root folder is also operated.

These are my personal changes.

The following is an online reference: (next)
