Parameter Passing problem
Hi All,

I developed a KSH script which will accept two parameters as input. These two parameters are some directories paths.

In the script i am validating the number of paramaters it received as below
#--------------------------------------
# Check Command line arguments
#--------------------------------------
if [ ${#} -ne 2 ]
then
echo " ${NOW} ${ScrName} : Invalid Parameter list..."
echo " ${NOW} ${ScrName} : Script needs TWO parameters"
echo " ${NOW} ${ScrName} : Param1--Input file path"
echo " ${NOW} ${ScrName} : Param2--Output file path"
exit 1
fi

and i am calling my script as
sh Script Name /home/raamch/work/infile /home/raamch/work/infile

script is giving the error as
+ [ 1 -ne 2 ]
+ echo Wed Jul 22 04:42:27 CDT 2009 SELUPDFLE.sh : Invalid Parameter list...
Wed Jul 22 04:42:27 CDT 2009 SELUPDFLE.sh : Invalid Parameter list...
+ echo Wed Jul 22 04:42:27 CDT 2009 SELUPDFLE.sh : Script needs TWO parameters
Wed Jul 22 04:42:27 CDT 2009 SELUPDFLE.sh : Script needs TWO parameters
+ echo Wed Jul 22 04:42:27 CDT 2009 SELUPDFLE.sh : Param1--Input file path
Wed Jul 22 04:42:27 CDT 2009 SELUPDFLE.sh : Param1--Input file path
+ echo Wed Jul 22 04:42:27 CDT 2009 SELUPDFLE.sh : Param2--Output file path
Wed Jul 22 04:42:27 CDT 2009 SELUPDFLE.sh : Param2--Output file path
+ exit 1


Even i tried the script calling as below
scriptname "path1" "path2"
scriptname "path1","path2"
scriptname 'path1' 'path2'

But no use.
script is not accepting the two parameters.

Please help me on how to pass directory paths as parameters to the KSH script.

link(2) 							System Calls Manual							   link(2)

NAME

       link() - link to a file

SYNOPSIS

DESCRIPTION

       The  system  call  creates a new link (directory entry) for the existing file.  path1 points to a path name naming an existing file.  path2
       points to a path name naming the new directory entry to be created.

RETURN VALUE

       Upon successful completion, returns zero.  Otherwise, it returns -1 and sets (see errno(2)) to indicate the error.

ERRORS

       The system call fails and no link is created if one or more of the following is true:

	      A component of either path prefix denies search permission.

	      The requested link requires writing in a directory
			     that does not permit writing.

	      The user's or group's disk quota block limit has been reached for this file system.

	      The link named by
			     path2 exists.

	      path	     points outside the allocated address space of the process.  The reliable detection of this  error	is  implementation
			     dependent.

	      Too many symbolic links were encountered in translating either path name.

	      The maximum number of links to a file would be exceeded.

	      Either the specified path exceeds
			     bytes, or a component of either specified path exceeds while is in effect.

	      The file named by
			     path1 does not exist.

	      A component of either path prefix does not exist.

	      path2	     points to a null path name.

	      path1	     or path2 is null.

	      The directory to contain the file cannot be extended.

	      A component of either path prefix is not a directory.

	      The file named by
			     path1  is	a  directory  and  the	effective user ID is not a user who has appropriate privileges.  Some file systems
			     return this error whenever path1 names a directory, regardless of the user ID.

	      The requested link requires writing in a directory
			     on a read-only file system.

	      The link named by
			     path2 and the file named by path1 are on different logical devices (file systems).
