printenv: Display the value of a variable and end with NUL instead of newline.
$ printenv --null ${HOME}
try on your machine
The command "printenv --null ${HOME}" is used to display the value of the environment variable "HOME" and separate it with null characters.
Here's a breakdown of the command:
- "printenv" is a command-line utility in Unix-like operating systems used to print all or part of the environment.
- "--null" is an option that specifies separating the output with null characters instead of newlines.
- "${HOME}" is the variable that represents the path to the user's home directory. It is enclosed in curly braces and preceded by a dollar sign to indicate that the shell should substitute its value.
So when you run this command, it will print the value of the "HOME" environment variable, followed by a null character instead of a newline character.
