What have you tried?
Take a look at:
Code:
ls -lt

https://www.unix.com/unix-dummies-que...ate-order.html
You will also want to search through the forums.

The above will show you how to see your files in date order. What do you think would be the next step?

Hello dude just try the below code
Code:
ls -lt | awk 'NR == 1 {next} {print $9}' | sed -ne '6,$p' | xargs rm -rf

You can save one pipe by replacing:
Code:
ls -lt | awk 'NR == 1 {next} {print $9}'

by
Code:
 ls -t -c1

... Unless you are trying to learn awk of course...Smilie

Hi,
Try this,
Code:
ls -lt | awk '{if(NR > 6){print "rm -f",$9;}}' | sh

ls -lt | awk '{if(NR > 6){print $9;}}' | xargs rm -f

Cheers,
Ranga:-)
