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)

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)

LEARN ABOUT OSF1
folders
folders(1) General Commands Manual folders(1)NAME
folders - list folders and contents (only available within the message handling system, mh)
SYNOPSIS
folders [+folder] [msg] [options]
OPTIONS
Lists only the name of folders, with no additional information. This is faster because the folders need not be read. Prints a list of the
valid options to this command. Lists the contents of the folder-stack. No +folder argument is allowed with this option. Re-numbers mes-
sages in the folders. Messages are re-numbered sequentially, and any gaps in the numbering are removed. The default operation is -nopack,
which does not change the numbering in the folder. Discards the top of the folder-stack, after setting the current folder to that value.
No +folder argument is allowed with this option. This corresponds to the popd operation in the C-shell; see csh(1). The -push and -pop
options are mutually exclusive: the last occurrence of either one overrides any previous occurrence of the other. Pushes the current
folder onto the folder-stack, and makes the +folder argument into the current folder. If +folder is not given, the current folder and the
top of the folder-stack are exchanged. This corresponds to the pushd operation in the C-shell; see csh(1). The -push switch and the -pop
switch are mutually exclusive: the last occurrence of either one overrides any previous occurrence of the other. Lists folders recur-
sively. Information on each folder is displayed, followed by information on any sub-folders which it contains. Displays only the total
number of messages and folders in your Mail directory. This option does not print any information about individual folders. It can be sup-
pressed using the -nototal option.
The defaults for folders are:
+folder defaults to all msg defaults to none -nofast -noheader -nototal -nopack -norecurse
DESCRIPTION
The folders command displays the names of your folders and the number of messages that they each contain.
The folders command displays a list of all the folders in your Mail directory. The folders are sorted alphabetically, each on its own line.
This is illustrated in the following example: Folder # of messages ( range ); cur msg (other files)
V2.3 has 3 messages ( 1- 3).
adrian has 20 messages ( 1- 20); cur= 2.
brian has 16 messages ( 1- 16).
chris has 12 messages ( 1- 12).
copylog has 242 messages ( 1- 242); cur= 225.
inbox+ has 73 messages ( 1- 127); cur= 127.
int has 4 messages ( 1- 4); cur= 2 (others).
jack has 17 messages ( 1- 17); cur= 17.
TOTAL= 387 messages in 8 folders.
The plus sign (+) after inbox indicates that it is the current folder. The information about the int folder includes the term (others).
This indicates that the folder int contains files which are not messages. These files may be either sub-folders, or files that do not
belong under the MH file naming scheme.
The folders command is identical to the effect of using the -all option to the folder command.
If you use folders with the +folder argument, it will display all the subfolders within the named folder. as shown in the following exam-
ple:
% folders +test Folder # of messages ( range ); cur msg (other files) test+ has 18 messages ( 1- 18);
(others). test/testone has 1 message ( 1- 1). test/testtwo has no messages.
TOTAL= 19 messages in 3 folders.
See refile(1) for more details of sub-folders.
