same file being opened by two users at a time
I want to avoid a situation where because two users simultaneously
open a file and modify and save, leaving the original file in mess.
Is there a way in UNIX to warn a user if that particular file is already being
used by another user.
Thanks in advance

warn.conf
warn.conf(4) File Formats warn.conf(4)
NAME
warn.conf - Kerberos warning configuration file
SYNOPSIS
/etc/krb5/warn.conf
DESCRIPTION
The warn.conf file contains configuration information specifying how users will be warned by the ktkt_warnd daemon about ticket expiration
on a Kerberos client. Credential expiration warnings are sent, by means of syslog, to auth.notice. All other warning messages are sent to
daemon.notice.
Each Kerberos client host must have a warn.conf file in order for users on that host to get Kerberos warnings from the client. Entries in
the warn.conf file must have the following format:
principal syslog | terminal | mail time [email_address]
principal Specifies the principal name to be warned. The asterisk (*) wildcard can be used to specify groups of principals.
syslog Sends the warnings to the system's syslog. Depending on the /etc/syslog.conf file, syslog entries are written to the
/var/adm/messages file and/or displayed on the terminal.
terminal Sends the warnings to display on the terminal.
mail Sends the warnings as email to the address specified by email_address.
time Specifies how much time before the TGT expires when a warning should be sent. The default time value is seconds, but you
can specify h (hours) and m (minutes) after the number to specify other time values.
email_address Specifies the email address at which to send the warnings. This field must be specified only with the mail field.
EXAMPLES
Example 1: Specifying warnings
The following warn.conf entry
* syslog 5m
specifies that warnings will be sent to the syslog five minutes before the expiration of the TGT for all principals. The form of the mes-
sage is:
jdb@ACME.COM: your kerberos credentials expire in 5 minutes
