Thanks for the reply.

I found this in my old book as a subsitue for ls command.

Code:
#!/bin/bash
#
for f in * ; do echo $f ; done

But here, I want to display only files when $ ./do_ls.sh files is entered.

and dir when $ ./do_ls.sh dirs is entered.

du

DU(1)									FSF								     DU(1)

NAME

       du - estimate file space usage

SYNOPSIS

       du [OPTION]... [FILE]...

DESCRIPTION

       Summarize disk usage of each FILE, recursively for directories.

       Mandatory arguments to long options are mandatory for short options too.

       -a, --all
	      write counts for all files, not just directories

       -B, --block-size=SIZE use SIZE-byte blocks

       -b, --bytes
	      print size in bytes

       -c, --total
	      produce a grand total

       -D, --dereference-args
	      dereference FILEs that are symbolic links

       -h, --human-readable
	      print sizes in human readable format (e.g., 1K 234M 2G)

       -H, --si
	      likewise, but use powers of 1000 not 1024

       -k     like --block-size=1K

       -l, --count-links
	      count sizes many times if hard linked

       -L, --dereference
	      dereference all symbolic links

       -S, --separate-dirs
	      do not include size of subdirectories

       -s, --summarize
	      display only a total for each argument

       -x, --one-file-system
	      skip directories on different filesystems

       -X FILE, --exclude-from=FILE
	      Exclude files that match any pattern in FILE.

       --exclude=PATTERN Exclude files that match PATTERN.

       --max-depth=N
	      print  the  total  for  a  directory  (or  file,	with  --all)  only  if	it  is	N or fewer levels below the command line argument;
	      --max-depth=0 is the same as --summarize

       --help display this help and exit

       --version
	      output version information and exit

       SIZE may be (or may be an integer optionally followed by) one of following: kB 1000, K 1024, MB 1,000,000, M 1,048,576, and so on for G, T,
       P, E, Z, Y.

PATTERNS

       PATTERN is a shell pattern (not a regular expression).  The pattern ?  matches any one character, whereas * matches any string (composed of
       zero, one or multiple characters).  For example, *.o will match any files whose names end in .o.  Therefore, the command

	      du --exclude='*.o'

       will skip all files and subdirectories ending in .o (including the file .o itself).
