[Larshg]

Hi

I need to have a command that will find the newest file in a directure structure

ex.
I have 2 directories where their are some file in
/test1
-rw-r--r-- 1 intecmd users 184525 Feb 24 16:10 /datafiles/comverse_smsc/COMV09A/bill.20040224151500
-rw-r--r-- 1 intecmd users 201517 Feb 24 16:10 /datafiles/comverse_smsc/COMV09A/bill.20040224153000
-rw-r--r-- 1 intecmd users 206021 Feb 24 16:10 /datafiles/comverse_smsc/COMV09A/bill.20040224154500
-rw-r--r-- 1 intecmd users 235080 Feb 24 16:40 /datafiles/comverse_smsc/COMV09A/bill.20040224160000
/test2
-rw-r--r-- 1 intecmd users 102829 Feb 19 00:25 /datafiles/comverse_smsc/COMV09B/20040218/bill.20040218233000
-rw-r--r-- 1 intecmd users 68499 Feb 19 00:25 /datafiles/comverse_smsc/COMV09B/20040218/bill.20040218234500
-rw-r--r-- 1 intecmd users 38847 Feb 19 00:40 /datafiles/comverse_smsc/COMV09B/20040219/bill.20040219000000
-rw-r--r-- 1 intecmd users 13391 Feb 19 00:40 /datafiles/comverse_smsc/COMV09B/20040219/bill.20040219000912
-rw-r--r-- 1 intecmd users 112 Feb 19 00:40 /datafiles/comverse_smsc/COMV09B/20040219/bill.20040219001329
-rw-r--r-- 1 intecmd users 51480 Feb 19 01:10 /datafiles/comverse_smsc/COMV09B/20040219/bill.20040219001500
-rw-r--r-- 1 intecmd users 5621 Feb 19 01:10 /datafiles/comverse_smsc/COMV09B/20040219/bill.20040219003000




I need a command that will always return the newest file in this case
-rw-r--r-- 1 intecmd users 235080 Feb 24 16:40 /datafiles/comverse_smsc/COMV09A/bill.20040224160000

I've tryede using find - but I cant get it to sort the files in different directories.


Regards Larshg

In ksh, you can try something like this:

t1=/test1/$(ls -t /test1 | head -1)
t2=/test2/$(ls -t /test2 | head -1)
[[ "$t1" -nt "$t2" ]] && echo $t1 || echo $t2

Hope This Help, PH.
