help in script

hi

I have few files in a location.

nat1
nat2
nat3

I want to use the latest file and pass it as an argument for a script to be executed. How can i do that.

the following script will process all the files:-

for i in `ls nat*`
do
<script>> $i
done

but i want to process only the latest file.

To get the last file in a directory you can try this one..
Quote:
ls|sort|tail -1
Hope that helps.

Or to get the newest, script >$(ls -t | head -1)

ls outputs files in sorted order so the sort is unnecessary in the command yongitz posted.

ls -ltr |tail -1

also should work

if you like to use for loop
Quote:
for i in `ls -rt|tail -1`
do
script $i
done
alternatively you can use :-

Quote:
latest=`ls -rt|tail -1`
script $latest
