Hi pamu,

Just tried and got the same result.

Code:
/tmp$: cat x.ksh
#!/bin/ksh

for checkdir in dir*
do
   echo "Checking ${checkdir}"

   if [[ -d "${checkdir}" ]] ; then
      echo "... ${checkdir} is a directory"
   elif [[ -h "${checkdir}" ]] ; then
      echo "... ${checkdir} is a symbolic link"
   fi
done
/tmp$: ls -ltrd dir*
drwxr-x--x   2 oracle   dba         4096 Aug 31 23:42 dir1
drwxr-x--x   2 oracle   dba         4096 Aug 31 23:42 dir2
lrwxrwxrwx   1 oracle   dba            4 Aug 31 23:43 dir3 -> /tmp
/tmp$: ./x.ksh
Checking dir1
... dir1 is a directory
Checking dir2
... dir2 is a directory
Checking dir3
... dir3 is a directory
/tmp$:

Also tried CarloM's suggestion and same problem.

Hi CarloM,

Tried your suggestion, unfortunately, now it goes like below:

Code:
tmp $: ls -ltrd dir*
drwxr-x--x   2 oracle   dba         4096 Aug 31 23:42 dir1
drwxr-x--x   2 oracle   dba         4096 Aug 31 23:42 dir2
lrwxrwxrwx   1 oracle   dba            4 Aug 31 23:43 dir3 -> /tmp
tmp $: cat y.ksh
#!/bin/ksh

for checkdir in dir*
do
   echo "Checking ${checkdir}"

   if [[ -h "${checkdir}" ]] ; then
      echo "... ${checkdir} is a directory"
   elif [[ -d "${checkdir}" ]] ; then
      echo "... ${checkdir} is a symbolic link"
   fi
done
tmp $: cat z.ksh
#!/bin/ksh

for checkdir in dir*
do
   echo "Checking ${checkdir}"

   if [[ -L "${checkdir}" ]] ; then
      echo "... ${checkdir} is a directory"
   elif [[ -d "${checkdir}" ]] ; then
      echo "... ${checkdir} is a symbolic link"
   fi
done
tmp $: ./y.ksh
Checking dir1
... dir1 is a symbolic link
Checking dir2
... dir2 is a symbolic link
Checking dir3
... dir3 is a directory
tmp $: ./z.ksh
Checking dir1
... dir1 is a symbolic link
Checking dir2
... dir2 is a symbolic link
Checking dir3
... dir3 is a directory
tmp $:

dircmp(1)							   User Commands							 dircmp(1)

NAME

       dircmp - directory comparison

SYNOPSIS

       dircmp [-ds] [-w n] dir1 dir2

DESCRIPTION

       The  dircmp  command  examines dir1 and dir2 and generates various tabulated information about the contents of the directories. Listings of
       files that are unique to each directory are generated for all the options. If no option is entered, a list is output indicating whether the
       file names common to both directories have the same contents.

OPTIONS

       The following options are supported:

       -d	Compares  the  contents  of files with the same name in both directories and output a list telling what must be changed in the two
		files to bring them into agreement. The list format is described in diff(1).

       -s	Suppresses messages about identical files.

       -w n	Changes the width of the output line to n characters. The default width is  72.

OPERANDS

       The following operands are supported:

       dir1	A path name of a directory to be compared.
       dir2

USAGE

       See largefile(5) for the description of the behavior of dircmp when encountering files greater than or equal to 2 Gbyte ( 2**31bytes).

ENVIRONMENT VARIABLES

       See environ(5) for descriptions of the following environment variables that affect the execution of dircmp: LC_COLLATE,	LC_CTYPE,  LC_MES-
       SAGES, and NLSPATH.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred. (Differences in directory contents are not considered errors.)

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
