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 .

I'm writing a script to find the oldest file in a directory. I know this can be done by using ls -rt | tail -1 but these are rather large directories and that can be somewhat slow since the script will be running constantly.
Are there any other ways to do this that would be faster? I looked to... (2 Replies)
Hi all,
I need your assistance in removing the oldest file in a directory.
I posted the same thread 3 days back and I got the following answer
ls -1 -t | tail -1 | xargs rm
which is not covering the case when there are directories older than the oldest file.
So, could you please... (2 Replies)
Hi all,
I am a newbie to scripting and I need your help regarding finding the oldest file in a particular directory. My intention is to remove that oldest file.
Are there any options available with the "find" command to do this..
Thanks in advance for your help

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. However, if something is done to the folder then... (4 Replies)

new
NEW(1) [nmh-1.5] NEW(1)NAME
new - report on folders with new messages
fnext - set current folder to next folder with new messages
fprev - set current folder to previous folder with new messages
unseen - scan new messages in all folders with new messages
SYNOPSIS
new [sequences] [-mode mode] [-folders foldersfile] [-version] [-help]
fnext is equivalent to new -mode fnext
fprev is equivalent to new -mode fprev
unseen is equivalent to new -mode unseen
DESCRIPTION
New in its default mode produces a one-line-per-folder listing of all folders containing messages in the listed sequences or in the
sequences listed in the profile entry "Unseen-Sequence". Each line contains the folder, the number of messages in the desired sequences,
and the message lists from the .mh_sequences file. For example:
foo 11.* 40-50
bar 380. 760-772 824-828
total 391.
The `*' on foo indicates that it is the current folder. The last line shows the total number of messages in the desired sequences.
New crawls the folder hierarchy recursively to find all folders, and prints them in lexicographic order. Override this behavior by provid-
ing foldersfile containing the pre-sorted list of folders new should check, one per line.
In fnext and fprev modes, new instead changes to the next or previous matching folder, respectively.
In unseen mode, new executes scan sequences for each matching folder.
FILES

PROFILE COMPONENTS
Path: To determine the user's nmh directory
Current-Folder: To find the default current folder
Unseen-Sequence: The name of the unseen message sequence
