process in background

Hi Guys,

I am facing some weird problem with my shell script. The script shows up a menu and for every ontion internally calls a shell script which start/stop various servers. When I am using '&' while calling the internal shell script so that the server run in the background. For exiting the script user need to use 'q'. ( if 'q' then 'exit' )

Now the problem is when I run the script, it start the server properly but if I do a Control+c or close the window the server in the background also stops. But if I use q to quit then nothing happens to the server and it continues to run perfectly.

Can anyone tell me the reason for that.

Thanks,
Ankur

XINIT(1)                                                      General Commands Manual                                                     XINIT(1)

NAME
xinit - X Window System initializer SYNOPSIS
xinit [ [ client ] options ... ] [ -- [ server ] [ display ] options ... ] DESCRIPTION
The xinit program is used to start the X Window System server and a first client program on systems that are not using a display manager such as xdm(1) or in environments that use multiple window systems. When this first client exits, xinit will kill the X server and then terminate. If no specific client program is given on the command line, xinit will look for a file in the user's home directory called .xinitrc to run as a shell script to start up client programs. If no such file exists, xinit will use the following as a default: xterm -geometry +1+1 -n login -display :0 If no specific server program is given on the command line, xinit will look for a file in the user's home directory called .xserverrc to run as a shell script to start up the server. If no such file exists, xinit will use the following as a default: X :0 Note that this assumes that there is a program named X in the current search path. The site administrator should, therefore, make a link to the appropriate type of server on the machine, or create a shell script that runs xinit with the appropriate server. Note, when using a .xserverrc script be sure to ``exec'' the real X server. Failing to do this can make the X server slow to start and exit. For example: exec Xdisplaytype An important point is that programs which are run by .xinitrc should be run in the background if they do not exit right away, so that they don't prevent other programs from starting up. However, the last long-lived program started (usually a window manager or terminal emula- tor) should be left in the foreground so that the script won't exit (which indicates that the user is done and that xinit should exit). An alternate client and/or server may be specified on the command line. The desired client program and its arguments should be given as the first command line arguments to xinit. To specify a particular server command line, append a double dash (--) to the xinit command line (after any client and arguments) followed by the desired server command. Both the client program name and the server program name must begin with a slash (/) or a period (.). Otherwise, they are treated as an arguments to be appended to their respective startup lines. This makes it possible to add arguments (for example, foreground and back- ground colors) without having to retype the whole command line. If an explicit server name is not given and the first argument following the double dash (--) is a colon followed by a digit, xinit will use that number as the display number instead of zero. All remaining arguments are appended to the server command line. EXAMPLES
Below are several examples of how command line arguments in xinit are used. xinit This will start up a server named X and run the user's .xinitrc, if it exists, or else start an xterm. xinit -- /usr/local/bin/Xvnc :1 This is how one could start a specific type of server on an alternate display. xinit -geometry =80x65+10+10 -fn 8x13 -j -fg white -bg navy This will start up a server named X, and will append the given arguments to the default xterm command. It will ignore .xinitrc. xinit -e widgets -- ./Xorg -l -c This will use the command .Xorg -l -c to start the server and will append the arguments -e widgets to the default xterm command. xinit /usr/ucb/rsh fasthost cpupig -display ws:1 -- :1 -a 2 -t 5 This will start a server named X on display 1 with the arguments -a 2 -t 5. It will then start a remote shell on the machine fasthost in which it will run the command cpupig, telling it to display back on the local workstation. Below is a sample .xinitrc that starts a clock, several terminals, and leaves the window manager running as the ``last'' application. Assuming that the window manager has been configured properly, the user then chooses the ``Exit'' menu item to shut down X. xrdb -load $HOME/.Xresources xsetroot -solid gray & xclock -g 50x50-0+0 -bw 0 & xload -g 50x50-50+0 -bw 0 & xterm -g 80x24+0+0 & xterm -g 80x24+0-0 & twm Sites that want to create a common startup environment could simply create a default .xinitrc that references a site-wide startup file: #!/bin/sh . /usr/local/lib/site.xinitrc Another approach is to write a script that starts xinit with a specific shell script. Such scripts are usually named x11, xstart, or startx and are a convenient way to provide a simple interface for novice users: #!/bin/sh xinit /usr/local/lib/site.xinitrc -- /usr/bin/X -br ENVIRONMENT VARIABLES
DISPLAY This variable gets set to the name of the display to which clients should connect. XINITRC This variable specifies an init file containing shell commands to start up the initial windows. By default, .xinitrc in the home directory will be used. FILES
.xinitrc default client script xterm client to run if .xinitrc does not exist .xserverrc default server script X server to run if .xserverrc does not exist SEE ALSO
