How do I turn file name colors (ls command colors) on or off in bash shell on Linux or Unix-like operating systems?

Most modern Linux distributions and Unix systems have an alias that defines the color of the file name. The ls command is then responsible for displaying the colors of files, directories, and other file system objects on the screen.

By default, file types are not distinguished by color. You need to pass the-- color option to the ls command on Linux. If you are using an OS X or BSD-based system, pass the-G option to the ls command. The syntax for turning colors on or off is as follows.

How to turn off the color of the ls command

Enter the following command:

$ls-color=none

Or use the unalias command to delete the alias:

$unalias ls

Notice that the following bash shell alias is defined to display colors with the ls command. This combination uses the alias command and the grep command:

$alias | grep ls

Sample output:

Alias l='ls-CF'alias la='ls-A'alias ll='ls-alF'alias ls='ls-- how color=auto' opens the color of the ls command

Use any of the following commands:

$ls-color=auto$ ls-color=tty

If you want, you can define the bash shell alias:

Alias ls='ls-color=auto'

You can add or remove ls aliases from ~ / .bash_profile or ~ / .bashrc files. Use a text editor such as vi to edit the file:

$vi ~ / .bashrc

Append the following code:

# my ls command aliases # alias ls ='ls-- color=auto'

Just save and close the file in the Vi/Vim text editor.

Notes on the ls command in * BSD/macOS/Apple OS X

$ls-G
