ππ» How to Change the Output Color of Echo in Linux π‘π§
Hey there, fellow tech enthusiasts! π Are you tired of the boring black and white output when using the echo command in Linux? π Well, fret no more because I've got you covered! In this guide, I'll show you how to effortlessly add some color to your terminal output using echo. ππ»
So, let's dive in and address this common issue head-on. The user is trying to print a text in the terminal using the echo command. They specifically want to know how to print the text in a red color. Let's see how we can achieve that! ππ΄
Solution: Utilizing ANSI Escape Sequences
To change the text color in Linux, we can leverage the power of ANSI escape sequences. These sequences allow us to manipulate the formatting and appearance of text in the terminal. πποΈ
To print text in red, simply append the respective escape sequence before your desired text. In this case, we need to use the "\e[31m" sequence. For example:
echo -e "\e[31mHello, world!\e[0m"
In the above command, -e
enables interpretation of backslash escapes, and \e[31m
sets the color to red. The Hello, world!
text will be printed in vibrant red. ππ
Colors Galore π¨π
But wait, there's more! Linux provides a whole spectrum of colors for you to choose from. Here are a few examples:
Black:
\e[30m
Blue:
\e[34m
Green:
\e[32m
Yellow:
\e[33m
Purple:
\e[35m
Cyan:
\e[36m
White:
\e[37m
You can mix and match these color codes to your heart's content. Get creative, and make your terminal output truly stand out!
Make it Stick! ππ―
So far, so good, right? But here comes a specific problem: what if you want to permanently change the color of your echo output? Well, my friend, we need to modify your shell configuration file. ππ»
If you're using Bash, open your ~/.bashrc
file using your favorite text editor and add the following line:
export PS1="\[\033[31m\]\u@\h:\w $ \[\033[0m\]"
This line modifies the PS1
environment variable, which controls the appearance of your command prompt. The "\[\033[31m\]"
sequence sets the color of the prompt, and "\[\033[0m\]"
resets it to the default color.
Save the file and restart your shell or run source ~/.bashrc
to apply the changes immediately. Voila! Your terminal will now have a dazzling red prompt. ππ
