Answer 2

Answer:

By setting the PATH environment variable

Explanation:

When we execute a command we do not have to give full path. This is possible because of PATH environment variable. This variable keeps the list of directory where you will find executable files.

If you want to know contents of path variable, then you need to type

echo $PATH
