I am looking for a way to remove files that haven't been accessed in approx. 45 minutes that are located in a specific directory. I know I can use find with something but I am not sure what to use in conjunction with it.

Hi

  Here is an example of using find with the parameters
you want.

To remove all files named a.out or *.o that have not been accessed for a week and that are not mounted using nfs, enter:

find / \( -name a.out -o  -name '*.o' \) -atime +7 ! -fstype nfs
-exec \ rm {} \;

Note:   The number used within the -atime expression is +7. This is
the correct entry if you want the command to act on files not accessed
for more than a week (seven 24-hour periods).

Unfortunatelly now i am at home, where a have no unix to
do some test.
 But i advise you to see man find for the parameters
 of this command.

  I have already used -atime because i needed to delete
a minimum of one day, not minutes as you want.

  Good luck

the -?time option is always using 24h steps, not quite what you are looking for. The better way might be the -newer <filename> option. It compares with the timestamp of an existing file (like "find \home\xxx -newer \home\test.file ! -exec \ rm {} \;") The problem is now to 'touch' the \home\test.file. I don't know how exact your 45 minutes have to be, but you could touch the file in a cronjob ...

Let us know ...

What about doing this, would it work?

find /directory -mmin +40 > temp.file
rm -r < temp.file

I haven't seen the -mmin option (what is your OS?), but the rm won't work.
If you have that -mmin, then do something like:
find /directory -mmin +40 -exec \ rm {} \;

Hi, it seems to be difficult (impossible?) to do something with find with smaller steps than one day, so I have another suggestion:
If you list the content of your directory with ls -lu, you will get the access time instead of modification time in the time column.  Futhermore, if you use ls -trlu the list will be sorted with the most recently accessed files at the bottom.
From here, you can probably make a script that analyzes the time colum and make the desired actions.

Since we didn't get any feedback from the asker about the precision needed, I claim that I provided a working solution.
