hi
I want to display the latest file in script.
say for example

file.txt1
file.txt2
file.txt3(latest)

in the script

var1=`ls -ltr file.txt* | tail-1`
echo $var1


This is what i am using. But this says that file.txt*: No such file or directory


To the same script if I pass file.txt* as parameter and
when i use the below it is working

var1=`ls -ltr $1 | tail-1`
echo $var1


Can some help me with first method

Thanks in advance
Ammu
