Bash to select oldest folder in directory automatically and log process
The `bash` below uses the oldest folder in the specified directory and logs it. The goes though an analysis process and creates a log. My problem is that if there are 3 folders in the directory folder1,folder2,folder3, the bash is using folder2 for the analysis eventhough folder1 is the oldest folder in the directory. Is the find command missing something? Also, is there a better way to log the folder used? That portion is in bold. Thank you .

In the bash below the oldest folder in a directory is selected. If there are 3folders in the directory /home/cmccabe/Desktop/NGS/test and nothing is done to them (ie. no files deleted, renamed) then the bash correctly identifies f1 as the oldest.
