Can anyone advise how do I use ls to do a selective amd sorted listing of file that I want to have as below?
Am looking for files that are named as log_<nnnn>.txt, where <nnnn> are numeric, i.e. I want to have a listing sorted from the newest to the oldest of files that starts with log_ and with a .txt extension and the characters in between these two can only be numeric, example log_1.txt, log_234.txt, log_222.txt etc.
I want to exclude files like log_9ab.txt, log_a9b.txt., log_99a.txt
I thought I can get away with doing
Code:
ls -1tr log_[0-9][0-9]*.xml
but unfortunately the * list also files like log_99a.txt.
I want to be able to only list files where the characters in between log_ and .txt are numeric, unfortunately, sometimes, there can be 2, 3 or 5 numeric characters.
Any advise will be much appreciated. Thanks in advance.

Hello,
I have been using the command below for file manipulation.
while read A B; do grep $f1; done < f2 > f3
So, if a certain string is found in f2 (for ex; DOG243435) and it is also present in f1, then print that string plus the contents of the line in which it was found onto f3.
