Get the absolute path of the latest file modified on a directory


Hi, as per the thread's title, I'm trying to get the absolute path of the file. Using ls and tail, I could the file I need but it won't show the absolute path. So I'm trying to do it using find, but not having success on it. Here's some snippets:

Code:
[oracle@mortonlx methodr]$ ls -ltr /home/oracle/admin/MORTOND/udump/
total 120
-rw-r----- 1 oracle oinstall   619 Oct 13 11:20 mortond_ora_12756.trc

-rw-r----- 1 oracle oinstall 19737 Oct 15 19:35 mortond_ora_12047.trc

[oracle@mortonlx methodr]$ find /home/oracle/admin/MORTOND/udump/ -type f -mmin 40 -print
[oracle@mortonlx methodr]$ 

Expected output:
/home/oracle/admin/MORTOND/udump/mortond_ora_12047.trc
Thank you very much!!

I guess I am confused. You already have the absolute path of the directory. Why don't you just append the file that you find with ls to that?

Your find command is only going to return a file that was changed 40 minutes ago. Not one that was changed 41 minutes ago or one that was changed 39 minutes ago.

Yeah, more like this, if this is the proper way:

Code:
[oracle@mortonlx methodr]$ echo "/home/oracle/admin/MORTOND/udump/"$(ls -tr /home/oracle/admin/MORTOND/udump/ | tail -1)
/home/oracle/admin/MORTOND/udump/mortond_ora_12047.trc
[oracle@mortonlx methodr]$
I just thought on the command

Code:
[oracle@mortonlx methodr]$ ls -tr /home/oracle/admin/MORTOND/udump/ | tail -1
mortond_ora_12047.trc
[oracle@mortonlx methodr]$
that there would be something like a:

Code:
[oracle@mortonlx methodr]$ reversebasename $(ls -tr /home/oracle/admin/MORTOND/udump/ | tail -1)

On the "find" command, I thought the -mmin would be any file that was modified within "n minutes", so like on the files above, a file that was modified/created within the last 40mins. Is that wrong?

Thanks again for the reply.
