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.

SVN_DIFF(3) 1 SVN_DIFF(3)
svn_diff - Recursively diffs two paths
SYNOPSIS
array svn_diff (string $path1, int $rev1, string $path2, int $rev2)
DESCRIPTION
Recursively diffs two paths, $path1 and $path2.
Note
This is not a general-purpose diff utility. Only local files that are versioned may be diffed: other files will fail.
PARAMETERS
o $path1
- First path to diff. This can be a URL to a file/directory in an SVN repository or a local file/directory path.
Note
Relative paths will be resolved as if the current working directory was the one that contains the PHP binary. To use the
calling script's working directory, use realpath(3) or dirname(__FILE__).
Warning
If a local file path has only backslashes and no forward slashes, this extension will fail to find the path. Always replace
all backslashes with forward slashes when using this function.
o $rev1
- First path's revision number. Use SVN_REVISION_HEAD to specify the most recent revision.
o $path2
- Second path to diff. See $path1 for description.
o $rev2
- Second path's revision number. See $rev1 for description.
RETURN VALUES
Returns an array-list consisting of two streams: the first is the diff output and the second contains error stream output. The streams can
be read using fread(3). Returns FALSE or NULL on error.
The diff output will, by default, be in the form of Subversion's custom unified diff format, but an external diff engine may be used
depending on Subversion's configuration.
NOTES
Warning
This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in
a future release of PHP. This function should be used at your own risk.
EXAMPLES
Example #1
Basic example
This example demonstrates the basic usage of this function, and the retrieval of contents from the stream:
<?php
list($diff, $errors) = svn_diff(
'http://www.example.com/svnroot/trunk/foo', SVN_REVISION_HEAD,
'http://www.example.com/svnroot/branches/dev/foo', SVN_REVISION_HEAD
);
if (!$diff) exit;
$contents = '';
while (!feof($diff)) {
$contents .= fread($diff, 8192);
}
fclose($diff);
fclose($errors);
var_dump($contents);
?>
The above example will output:
Index: http://www.example.com/svnroot/trunk/foo
===================================================================
--- http://www.example.com/svnroot/trunk/foo (.../foo) (revision 23)
+++ http://www.example.com/svnroot/branches/dev/foo (.../foo) (revision 27)
// further diff output
Example #2
Diffing two revisions of a repository path
This example implements a wrapper function that allows a user to easily diff two revisions of the same item using an external
repository path (the default syntax is somewhat verbose):
<?php
function svn_diff_same_item($path, $rev1, $rev2) {
return svn_diff($path, $rev1, $path, $rev2);
}
?>
Example #3
Portably diffing two local files
This example implements a wrapper function that portably diffs two local files, compensating for the realpath(3) fix and the back-
slashes bug:
<?php
function svn_diff_local($path1, $rev1, $path2, $rev2) {
$path1 = str_replace('\', '/', realpath($path1));
$path2 = str_replace('\', '/', realpath($path2));
return svn_diff($path1, $rev1, $path2, $rev2);
}
?>
