Yes, there is
If you don't want to store the output in your script
system ('ls -ltr | tail -5');
Make sure you check $?
If you want the output inside your perl script
my @files = `ls -ltr | tail -5`;
Check $? here too
You can use open
open (FILELIST, 'ls -ltr | tail -5 |') or
die "Failed to exec: $!\n";
while (<FILELIST>) {
# Your code
}
close (FILELIST);
perldoc -f open
If you want pure perl code
perldoc -f glob
perldoc File::Glob
perldoc -f -x
perldoc -f sort
