will the above command work if i am using *.lst instead of p*

Code:
ls -tr1 *.lst|awk -F"." '{A[$1]=$0}END{for(i in A){print A[i]}}'

---------- Post updated at 01:54 PM ---------- Previous update was at 01:45 PM ----------

in the above code , you are dividing the file name in 4 fields
Code:
$1=p1
$2=txt
$3=201305051200
$4=lst

is it correct?

and then you are using

Code:
A[p1]=$0

, here $0 represents the full line if i am not wrong. i.e.

Code:
A[p1]=p1.txt.201305051200.lst

why in END used?

---------- Post updated at 02:14 PM ---------- Previous update was at 01:54 PM ----------

can you use full file name as index like p1.txt instead of just p1.
because if there are file like

Code:
p1.txt.201306051200.lst
p1.201306051200.lst

now there are two different files name one is p1.txt and the other is only p1.
so the above code just picks only one of the file.
