Sort by name, time, and size
How do you combine these ls commands so that I can have the outputs by name, time stamp, and size?

Code:
ls -al |grep name_of_file
ls -al | sort +4nr
ls  -l -t

Please advise.

Surprising post for someone with your experience.
It always helps to post what Operating System and version you are running and what Shell you prefer:
I'll assume some sort of mainstream unix and a mainstream Shell. Hope this is what you mean:

Code:
(
echo "Directory listing by name (alphabetic)"
ls -la
echo "Directory listing by timestamp (ascending)" 
ls -latr
echo "Directory listing by size (descending)"
ls -al | sort -n -r +4
) | more

In each of these commands you can insert a grep -v total to get rid of the total line from ls.

Sorry, I am on AIX 6.1 with KSH.

I should have clarified better...
I was wondering if we can combine all of the three ls commands together so that the output shows, i.e.
PHP Code:
aaa* listed by the timestamp (desc order) and then size.
then move onto the next 
bbb* listed by the timestamp (desc order) and then size.
then move onto the next 
ccc* .... 
Wildcard search would be helpful as to the file names might have different ends, i.e.
PHP Code:
dm_rmc_rdds_mail100506.log, dm_rmc_rdds_mail100527.log, cpmqlen_app2_apr13.csv, cpmqlen_app2_apr23.csv, etc. 
Please advise.

In order to sort by time you have to use mtime in seconds. That means perl or C.

Here is a simple perl subroutine to get mtime plus some shell
Code:
#!/bin/ksh
tags()
{
   perl -e '
    ($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,$atime,$mtime,$ctime,$blksize,$blocks)           
        = stat("$ARGV[0]");
     print "$ARGV[0] $mtime $size", "\n"; ' $1   

}
ls | grep -v total | 
while read fname 
do
    tags $fname 
done | sort -k1 -k2n -k3n | 
 while read f dummy
 do
     ls -l $f
 done

This gives a full listing ordered by name, mtime and size.

This becomes a bit tricky. many files i.e. have different suffixes, which makes the sorting a bit difficult to read..
Is there any way to ignore the suffix and sort them?
