You are welcome.

I think I encounter a strange thing.My code can run normally on sun solaris OS. I swear.

I wonder if you can tell me your platform.SCO UNIX?HP UNIX?
Perhaps the bug is caused by the version of unix OS.

I modified the code.If you input the "exit",You can quit the shell.

-------------------------------------------------------------------
#!/usr/bin/ksh

agreed=
while [ x$agreed = x ];
do
printf "Ready:$>"
read receive
if [ "$receive" = "exit" ]
then
exit 1;
fi
ksh -c "$receive"
done
--------------------------------------------------------------------

NAME
ctrlaltdel - set the function of the Ctrl-Alt-Del combination SYNOPSIS
ctrlaltdel hard|soft DESCRIPTION
Based on examination of the linux/kernel/sys.c code, it is clear that there are two supported functions that the Ctrl-Alt-Del sequence can perform: a hard reset, which immediately reboots the computer without calling sync(2) and without any other preparation; and a soft reset, which sends the SIGINT (interrupt) signal to the init process (this is always the process with PID 1). If this option is used, the init(8) program must support this feature. Since there are now several init(8) programs in the Linux community, please consult the documentation for the version that you are currently using. ctrlaltdel is usually used in the /etc/rc.local file. FILES
/etc/rc.local SEE ALSO
simpleinit(8), init(8) AUTHOR
Peter Orbaek (poe@daimi.aau.dk) AVAILABILITY
The ctrlaltdel command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/. util-linux October 1993 CTRLALTDEL(8)
