Thank a lot.

#!/bin/ksh
# aix 5.3
MDIR=/phx
for i in $MDIR/{load,utility,src}
do
cd $i
find $i ! -type d -print
done

Result as below, But How to filter out backup copy *.yyyymmdd_hhss ?
$ test_ls.ksh
/phx/load/abc
/phx/load/abc.20100326_2301
/phx/load/abc.20100327_1338
/phx/load/abcd
/phx/utility/abc1.ksh
/phx/utility/ut001.p
/phx/utility/ut002.p
/phx/src/abc.p

Have you inspected the man page of find (or grep)?

The point is that $MDIR/{load,src} may contain $IFS.

That is pointless, and a standalone -print is superfluous. You only need
this one line (and no script file at all):

find $MDIR/{load,utility,src} ! -type d

man find | less -p '-regex pattern'

He obviously meant that one couldn't use the existence of
extensions to select only non-directory files with wildcards.

Many files in Linux have extensions and their are quite a few
common apps and utilities that won't accept files if they don't
have the preper extensions. Like gunzip.

Using the file "todo" as an example:

$gzip todo
$mv todo.gz todo
$gunzip todo
gzip: todo: unknown suffix -- ignored

You are a stupid and ignorant jerk.
