How is a dot in the path interpreted?

Question

linux

Can you explain what dot means in file path?
. - points to the current directory
.. - the directory above or the parent directory of the source directory
What does this path mean?

/bin/linux-x86-64/./test.pid

Answer 1

Special Entries. and .. are not just "interpreted", they are actual directory entries about the current (.) and parent (..) directories. So a dot in the path means "same directory" and can be painlessly removed from the string.
