Two stage process. Generate the filename(s) with "ls" (or "find") then find out the size.

Code:
ls -1 *\.edf | while read filename
do
        filesize=`ls -lad "${filename}"|awk '{print $5}'`
        echo "filename : ${filename}"
        echo "filesize : ${filesize}"
done

or:
Code:
#!/bin/ksh

ls -l *\.edf| while read -r a a a a s a a a n
do
  echo "[$s] [$n]"
done

Code:
ls -lrt *.edf | cut -d" " -f7- | sed 's/[A-Z][a-z][a-z] [0-9][0-9 ] [0-9][0-9]:[0-9][0-9] //'

Does not work with a normal "ls" listing (though the one posted is strangely spaced).

methyl,
did you run my command and it did not work for you? There was a small error, because the initial regex was for systems which have 00 Mon format in the ls -l output (where 00 represents the day and Mon month). I've adjusted the regex for Mon 00 format. Maybe you want to run it again?
However "ls -lrt *.edf | cut -d" " -f7-" always worked pretty nice for me Smilie

How about this?:

Code:
ls -lrt -D %\  *.edf | awk '{print substr($0, index($0,$5))}'

Why not just use sed?

Code:
ls -lrt *.edf | sed 's/.*:.. //g'
