I am reading a directory and creating an array of .png file names. I
know for a fact that there are 1025 png files in the folder
With $count = @files I get 1027
With $last = $#files I get 1026
$files [0] = .
$files[1] = ..
"." is the current directory, ".." is the parent directory.
These are always inserted by the filesystem in any directory for
navigation purposes. These are (in principle) dynamically generated
abbreviations for directory names.
Simply put
.. is needed when you need to go up one level higher in the file
hierachie without parsing the current path, like "cd .."
. is mostly needed on the command line, when you want to execute a
program from the current directory if its not in the search path, like
"./myapp".
