I input the command:
$ ls -lasrt
And the output includes (there are more results, these are the ones that confuse me):
4 drwxr-xr-x 5 tuc40953 stdchem 4096 Jul 3 17:48 ..
4 drwxr-xr-x 2 tuc40953 stdchem 4096 Jul 5 10:03 .
Could this mean that the last things that were written are in the previous directory?
