I'm looking for a Bash script that will go into a list of directories and delete all but the four most recently created files.
How can I do this?
I'm trying to keep a directory full of log files manageable. Nightly, I want to delete all but the 10 most recent. How can I do this in a single command?

I'm working on a bash script that will go through a directory, find the sub-directories that have been created since the last time the script ran, count the results, and output that integer (will most likely be '1' or less per each instance run) to a file. Give the circumstances, my previous (and very limited) experience with bash is not sufficient for me to pull this off. since it probably has bearing, is that my mail server stores files that it flags as viruses in a folder. It creates a sub-directory for each virus that it quarantines .I want to count those subdirectories and graph them with MRTG. Hence the script. I'm going to post what I've got so far and the purpose of it, because I'm told I have a very odd and efficient way of doing scripting.

But then it dawned on me that it wouldn't work because I would have to not count the directories that have already been counted and count the ones that have not been counted. Given that the purpose of this is to generate a graph about every 5 minutes, using find won't work because, to my knowledge, that will only find things based on whole day values, I need it almost down to the minute.
Basically, I am trying to locate and copy the newest .json bookmark backup in my .mozilla/firefox/w987sdg9.default/bookmarkbackups directory.
I tried this
Code:
ls -t ~/.mozilla/firefox/b1ahb1ah.default/bookmarkbackups/ | head -1
which does return the newest file, but only the filename itself. I found readlink, but I haven't gotten that to output a full path which I can then feed to copy. So, it seems to me that find might work well here, and I know how to find based on absolute dates, but not relative.

I have 5 FTP users that upload files (and subdirectories) in their home directory, i need to mirror theese directories beetween them and with a "master" directory (accessible from a 6th user). Files can contain spaces or others special caracters. All the files are in the same filesystem, and i want to use hard link because i don't want to waste 5 time the space of a single file. I tried with find but i cannot handle spaces in it.

I want to copy all directories, files, and hidden files and hidden directories with one command. I want these items to replace any same items in the target directory.
I have tried several things, such as:
cp -r *
cp -aR *
but I only seem to get visible files and directories. Obviously, I am missing something. (A brain, probably....)

I am administrating a lab in a university and every semester we need to delete all the home folders of the accounts for the next semester. I would like to make a bash script that does this automatically and having trouble with it. Note that I am writing my very first bash script. What I need to do is make a script to delete the following:
Delete everything in /home/$exp$num/$dir
when "exp" could be either "rt", "ic" or "sp".
"num" could run from 1(single digit) to 45 and dir is "profile" and "work".
This is what I tried to write:
Code:
#!/bin/sh
cd /home
for exp in "rt ic sp"
do
[code]....
What seems to be the problem is the reading of "$exp$num" as a joint expression.

3.State what kinds of files are stored in the following directories. Give any ONE file that can be found in these directories.
a. /etc/
b. /proc/
c. /sbin/
If I execute the following command:
cp -R /myfiles /mydestination
If myfiles contains several sub-directories and files, in what order will they be copied? For example, directories might be named 0123a, 9993c, myfolder, xfolder.
They are not copied in alphabetical order OR in date order OR in the order they appear when using a standard ls command as far as I can tell, so what actually does determine the order?
Edit:
I am trying to determine the order that the cp command uses in order to determine how far along my copy command made it before it stopped. For example, I was hoping to be able to determine it copied 3 of the 4 directories successfully.
