export: Append something to the PATH variable.

export

$ export PATH=$PATH:${path-to-append}

try on your machine

This command is used to modify the environment variable PATH by appending a specific directory to it.

Here's a breakdown of the command:

export: This is a shell command used to set or modify environment variables in Unix-like operating systems. In this case, it is used to modify the PATH variable.
PATH: This is an environment variable that contains a list of directories in which the operating system looks for executable files. When a user executes a command, the operating system searches for it in the directories specified in the PATH variable.
$PATH: This is a variable reference to the current value of the PATH variable. By using $PATH, we ensure that any existing paths present in PATH are preserved.
${path-to-append}: This is the directory that we want to append to the existing PATH variable. It should be replaced with the actual directory path that you want to append.

So, when you execute the command export PATH=$PATH:${path-to-append}, the existing value of PATH will be preserved, and the specified directory will be appended to it, allowing the operating system to search for executable files in the appended directory as well.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
