regarding tracking file updates on linux networking environment
could anyone Explain me with how the linux o/s keeps track of file
updates in network environment? for example, assume that more than one
computer is connected to network (with linux in all of them). if an
user say 'X' logged into terminal 1 and created a file with the name
of 'temp.txt'. The file would be stored in his computer's local hard
disk. right? then, how come the 'temp.txt' file would still be
accessible if user 'X' logs on to different terminal say terminal 2
(Eventhough it doesn't have file 'temp.txt' in it's local
harddisk)?? . Assume that we are not doing any explicit transfer of
file.
any help with my problem will be greatly appreciated..

ctrlaltdel
CTRLALTDEL(8) Linux Programmer's Manual CTRLALTDEL(8)
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

AUTHOR

AVAILABILITY
The ctrlaltdel command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
