Bash script: issue changing directories in script
I am working on a script that checks two arguments at the command line. The first argument is a search pattern, the second can be a file or a directory, if it is a file a second script is called that checks it for the search pattern. If the second argument is a directory, it checks for the search pattern in all files in the that directory.
The script works ok if the second argument is a sub-directory of the working directory of the script. The issue occurs when the script needs to change directories. I don't think it likes the "/" if I specify a directory, but i'm stuck as far figuring out what to do next.

Here is the snippet of code I am having the trouble with:
Code:
elif [ -d $2 ]   #test the command line argument for a directory
then
#change directories to the the second command line argument
        cd $2
        filename=`ls -l | cut -c59-78`
        for entry in $filename
        do
        # Verify that the name read in the directory is a file
                if [ -f $filename ]
                then
        # Search the files for the pattern specified by $1, then call search.sh
            ./search.sh $1 $listing

service

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
       directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script,  service  passes  COMMAND and OPTIONS it to the init script unmodified.  All scripts should support at least the start and
       stop commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the  start
       command.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
