Linux printenv command

The printenv command in Linux is used to display the values of environment variables. Environment variables are dynamic values that provide information and configuration settings to programs running on the system.

To use the printenv command, simply open a terminal and type:


This will display a list of all the environment variables and their corresponding values.

If you want to search for a specific environment variable, you can pipe the output of printenv to the grep command. For example, to find the value of the PATH variable:

printenv | grep PATH

This will display the value of the PATH variable or any other variables containing the term “PATH” in their names.

The printenv command is useful for checking the values of environment variables, which can be important for troubleshooting, script development, or understanding the current system configuration.
