Top Forums UNIX for Dummies Questions & Answers restarting a while loop Post 38789 by RTM on Friday 25th of July 2003 10:29:39 AM

Since you didn't post your whole script (or at least the complete while loop ), the isn't much I can say about it since it works as far as checking for differences and sleeping. The minute it finds a difference, then it runs an endless loop - making assumtions about how you have it set up as follows:
last_alert.tmp is set up the same as new_alert.tmp (tail of /var/adm/messages).
while it's running, I change last_alert.tmp to cause the program to go to the else statement.
Code:
#!/bin/ksh
tail /var/adm/messages > new_alert.tmp
while true
do
diff new_alert.tmp last_alert.tmp
if [ $? -eq 0 ]
then
        echo No new alert messages `date`
        sleep 15
else
        continue
fi
done
exit

You really need to give more information.

genufi

genufi(8)						      System Manager's Manual							 genufi(8)

NAME

       genufi - Generates a User File Inventory (UFI) file

SYNOPSIS

       /usr/bin/genufi

DESCRIPTION

       The genufi utility creates a User File Inventory (UFI) file that contains the names of user files created or copied to your system after an
       installation.  Some of these files reside on file systems that are overwritten during a new installation of the operating system. You  must
       have superuser privileges to run the genufi utility, and you must invoke the genufi utility from the /usr/.smdb.  directory.

       To  create the UFI file, the genufi utility checks the Master Synchronization Inventory (MSI) file created by the invsync utility to deter-
       mine which file systems will be overwritten by a complete installation.	The genufi utility searches those file systems for user files  and
       writes these entries to the UFI file.  File systems that remain intact during a new installation of the operating system are not searched.

       The  genufi utility also filters out certain files and directories that would not commonly be considered for backup.  For example, some log
       files, installation files, and temporary directories do not need to be restored after a complete installation and are not  written  to  the
       UFI file.

       The following directories are not included:

       /tmp /tmp /usr/.smdb.  /usr/sys/HOST /var/adm/smlogs /var/adm/syslog.dated /var/rwho /var/tmp

       In the previous list, HOST represents the hostname of the system (such as /usr/sys/BLUTO) on the system named bluto.

       The following files are not included:

       */core */*.dummy */.new..  /osf_boot */.profile */.proto..  /var/adm/binary.errlog /var/adm/xdm/xdm-pid */vmcore /*vmunix

       Edit  the  UFI  file  to remove the entries for files and directories that you do not want to back up. The UFI file is written in the setld
       inventory file format.  Refer to the stl_inv(4) reference page for more information.

RESTRICTIONS

       You must have superuser privileges to run the genufi utility.

       You must invoke the genufi utility from the /usr/.smdb.	directory.

FILES

       Master Synchronization Inventory file User File Inventory file
