thanks for the reply. yes this is what i am trying to do. for the script to allow the user to define the file they wish to watch, then the script takes it in, and loads the monitor with their selected file. iv implemented your code and im getting an error message. this is a section of my code so far:

Code:
echo "please enter the file you wish to monitor";
read fname;
while true; do
read -p "are you sure you want to monitor the file: $fname?" yn

case $yn in
      [Yy]*) if [ -d $fname]; then 
           for i in $fname/*; do
               ./desktop/monitor $fname &
           done
       fi;;

[Nn]* ) exit;;


the error message im gettin is [: missing `]'
its from the line:

Code:
[Yy]*) if [ -d $fname]; then

DISPLAYS(5)							File Formats Manual						       DISPLAYS(5)

NAME

       displays - Display Configuration File

DESCRIPTION

       The  interactive  graphics  programs Caesar, Magic, and Gremlin use two separate terminals: a text terminal from which commands are issued,
       and a color graphics terminal on which graphical output is displayed.  These programs use a displays file to associate their text  terminal
       with its corresponding display device.

       The  displays file is an ASCII text file with one line for each text terminal/graphics terminal pair.  Each line contains 4 items separated
       by spaces: the name of the port attached to a text terminal, the name of the port attached to the associated graphics terminal,	the  phos-
       phor type of the graphics terminal's monitor, and the type of graphics terminal.

       An applications program may use the phosphor type to select a color map tuned to the monitor's characteristics.	Only the std phosphor type
       is supported at UC Berkeley.

       The graphics terminal type specifies the device driver a program should use when communicating with its graphics terminal.  Magic  supports
       types  UCB512, AED1024, and SUN120.  Other programs may recognize different display types.  See the manual entry for your specific applica-
       tion for more information.

       A sample displays file is:

	    /dev/ttyi1 /dev/ttyi0 std UCB512
	    /dev/ttyj0 /dev/ttyj1 std UCB512
	    /dev/ttyjf /dev/ttyhf std UCB512
	    /dev/ttyhb /dev/ttyhc std UCB512
	    /dev/ttyhc /dev/ttyhb std UCB512 (R)

       In this example, /dev/ttyi1 connects to a text terminal.  An associated UCB512 graphics terminal with standard  phosphor  is  connected	to
       /dev/ttyi0.

FILES

       Magic uses the displays file ~cad/lib/displays.	Gremlin looks in /usr/local/displays.
