Unable to check if file exists on remote server using expect

Hi,

I need to check if a file exists on remote server using expect.

Code:
#!/bin/bash
ip_addr=10.10.10.10
user=root
passwd=Help
filename=/root/test
expect -c "
spawn ssh -n -T -o NumberOfPasswordPrompts=3 -o StrictHostKeyChecking=no $user@$ip_addr
expect \"*?assword:*\"
send -- \"$passwd\r\"
expect {
\"ls $filename\" { exp_continue }
$filename { puts found }
timeout { puts \"timed out\" }
}
"

The above code is not working. I need to capture the output and if file does not exist, i need to perform some steps. Any other approach using expect only will be appreciated as I cannot do key sharing.
Please help.

chown - Changes file owner

SYNOPSIS
bool chown (string $filename, mixed $user) DESCRIPTION
Attempts to change the owner of the file $filename to user $user. Only the superuser may change the owner of a file. PARAMETERS
o $filename - Path to the file. o $user - A user name or number. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Simple chown(3) usage <?php // File name and username to use $file_name= "foo.php"; $path = "/home/sites/php.net/public_html/sandbox/" . $file_name ; $user_name = "root"; // Set the user chown($path, $user_name); // Check the result $stat = stat($path); print_r(posix_getpwuid($stat['uid'])); ?> The above example will output something similar to: Array ( [name] => root [passwd] => x [uid] => 0 [gid] => 0 [gecos] => root [dir] => /root [shell] => /bin/bash ) NOTES
Note This function will not work on remote files as the file to be examined must be accessible via the server's filesystem. Note When safe mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as the script that is being executed. SEE ALSO
chmod(3), chgrp(3). PHP Documentation Group CHOWN(3)
