What is the difference between these two file paths:
/docs/unix
docs/unix
Group of answer choices:
The first filepath starts at the root directory of the
filesystem, whereas the second path starts at the user's home
directory.
The first filepath is an absolute filepath, whereas the second
filepath is a relative filepath.
There is no difference: the leading '/' is ignored by the
shell.
The first filepath starts at the current directory, whereas the
second filepath starts at the root directory of the filesystem.
