Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:

something is wrong with my output

2. Relevant commands, code, scripts, algorithms:

it has something to do with the expr command, i don't know what is wrong though.

3. The attempts at a solution (include all code and scripts):

Code:
#!/bin/sh

#James Brooks
#COP3353 - Assignment 4
#4/23/10

file=$1
directories=0
files=0
rfiles=0
xfiles=0
wfiles=0

if [ $# -ne  1 ]
   then
        echo "Usage: assignment4.sh <directory_name>"
exit
fi


if [ ! -d $file ]
then
        echo "$file: is not a directory"
exit
fi
        

for filename in $file/*
     do
        if [ -r $filename ];
            then 
             rfiles = `expr $rfiles + 1`   
        fi

        if [ -x $filename ]
           then
                xfiles = `expr $xfiles + 1`
        fi
 if [ -w $filename ] 
           then  
                wfiles = `expr $wfiles + 1`
        fi

        if [ -d $filename ]
           then
                directories = `expr $directories + 1`
        fi
        if [ -f $filename ] 
           then  
                files = `expr $files + 1`  
        fi
done
        
echo "Total number of directories: $directories"
echo "Total number of files: $files"
echo "Total number of readable items: $rfiles"
echo "Total number of writable items: $wfiles"
echo "Total number of executable items: $xfiles"

ezstream-file

EZSTREAM-FILE.SH(1)					    BSD General Commands Manual 				       EZSTREAM-FILE.SH(1)

NAME

     ezstream-file -- script to stream files from the command line

SYNOPSIS

     ezstream-file [-hnqVv] [-T cfg_template] [file ...]

DESCRIPTION

     The ezstream-file script uses an ezstream configuration file template to stream a list of files given on the command line, or via standard
     input.  In other words, filenames are written to a temporary playlist, and a template-based configuration is generated to stream them.

     The path to a configuration template must be provided, either by using the -T command line argument, or the EZSTREAM_TEMPLATE environment
     variable.

     The configuration template must be a valid playlist configuration, and contain the follwing configuration statement:

	   <filename>%FILENAME%</filename>

     If no input files are specified, the list of files to be streamed are read from standard input.

     Lastly, the EZSTREAM environment variable allows to specify an alternate ezstream binary.

   Command line parameters
     -h      Print a summary of available command line parameters with short descriptions and exit.

     -n      (Passed to ezstream.)  Normalize metadata strings by removing excess whitespaces.

     -q      (Passed to ezstream.)  Be more quiet.  Suppress the output that external programs send to standard error.

     -T cfg_template
	     Use the configuration in cfg_template, overriding the default set in the EZSTREAM_TEMPLATE environment variable.

     -V      Print the ezstream-file version number and exit.

     -v      (Passed to ezstream.)  Produce more verbose output from ezstream.	Use twice for even more verbose output.

FILES

     /usr/share/doc/ezstream/examples  Directory containing example configuration files for various uses of ezstream, as well as example playlist
				       and metadata scripts.
