HELP on checking for directory or symbolic link
Hi,

Can anyone please advise why the following is not working as I expected it to be?

Test script as below:

Code:
#!/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

Output from sample run as below:

Code:
$: ./x.ksh

Checking dir1
... dir1 is a directory
Checking dir2
... dir2 is a directory
Checking dir3
... dir3 is a directory

Directory listing as below:

Code:
$: ls -l
total 24
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
-rwxr-----   1 oracle   dba          239 Aug 31 23:45 x.ksh

Am kinda hoping that it will report dir3 as a symbolic link. At the moment, only workaround I can think of is to do ls -l ${checkdir} | grep "^l" and if it is non-zero then it is a symbolic link, otherwise it is not. Is this the solution?

I've also tried doing -L instead of -h and it gives the same result.

Feedback and advise much appreciated. Thanks in advance.

paps

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.
	      Please notice this option isn't related to the terminal length as in a "80 culums terminal".

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do right to left (RTL) layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter and A4. Default is A4.

       Postscript points
	      Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch.

       --bottom-margin=bm
	      Set bottom margin. Default is 36 postscript points.

       --top-margin=tm
	      Set top margin. Default is 36 postscript points.

       --left-margin=lm
	      Set left margin. Default is 36 postscript points.

       --right-margin=rm
	      Set right margin. Default is 36 postscript points.

       --gutter-width=gw
	      Set gutter width. Default is 40 postscript points.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
