How to compare prev day file to current day file
Hi all:
I am new to this board and UNIX programming so please forgive if I don't explain something correctly.
I am trying to write a script to keep track of our links, we link one program written for Client A to Client B's directory.
What we want to do is to keep track of our linked programs to be sure they aren't getting unlinked, or lost. Track any changes from day to day. This script will be run from cron nightly.
My plan was to do an ll -R in 2 directories (LINKLOG and LINKTESTLOG that contain the programs, do a find of all links. sdiff from the previous days links to current days links, report any differences, compress all files except for the sdiff output, keep a month worth of daily history.
Sound like a nightmare??? It is. Here is what I have so far, but I am having a problem figuring out how to name/compare files....
Any help would be greatly appreciated!
LINKLOG=/funded/history
LINKTESTLOG=/test/history
FILEDATE=`date +%m%d%Y`
#Search all release versions within directory
for i in [4-9][0-9]/funded/test;
do
ll -R $i >> $LINKTESTLOG/testfile.log;
done
#
# Search funded directory.
for i in /funded;
do
ll -R $i >> $LINKLOG/rcsfile.log;
done
#Find all links and name using date to keep track
for i in $LINKTESTLOG/testfile.log
do
find. -type l print >$LINKTESTLOG/log.$FILEDATE
done
#Find all links and name using date to keep track
for i in $LINKLOG/rcsfile.log
do
find. -type l print >$LINKLOG/log.$FILEDATE
done
sdiff $LINKTESTLOG/log # HOW TO SDIFF previous day file to today file??
compress #ALL EXCEPT sdiffs
#Remove or save files as needed.
Any info as I said would be greatly appreciated.

doveadm-log
DOVEADM-LOG(1) Dovecot DOVEADM-LOG(1) NAME
doveadm-log - Locate, test or reopen Dovecot's log files SYNOPSIS
doveadm [-Dv] log errors [-s min_timestamp] doveadm [-Dv] log find [directory] doveadm [-Dv] log reopen doveadm [-Dv] log test DESCRIPTION
The doveadm log commands are used to locate and reopen the log files of dovecot(1). It's also possible to test the configured targets of the *log_path settings. OPTIONS
Global doveadm(1) options: -D Enables verbosity and debug messages. -v Enables verbosity, including progress counter. COMMANDS
log errors doveadm log errors [-s min_timestamp] The log errors command is used to show the last - up to 1,000 - errors and warnings. If no output is generated, no errors have occurred since the last start. -s min_timestamp An integer value, representing seconds since the epoch - also known as Unix timestamp. When a min_timestamp was given, doveadm(1) will only show errors occurred since that point in time. log find doveadm log find [directory] The log find command is used to show the location of the log files, to which dovecot(1) sends its log messages. If dovecot(1) logs its messages through syslogd(8) and doveadm(1) could not find any log files, you can specify the directory where your syslogd writes its log files. log reopen doveadm log reopen This command causes doveadm to reopen all log files, configured in the log_path, info_log_path and debug_log_path settings. These settings are configured in /etc/dovecot/conf.d/10-logging.conf. This is for example useful after manually rotating the log files. log test doveadm log test This command causes doveadm to write the message "This is Dovecot's priority log (timestamp)" to the configured log files. The used prior- ities are: debug, info, warning, error and fatal. EXAMPLE
This example shows how to locate the log files used by dovecot(1). doveadm log find Looking for log files from /var/log Debug: /var/log/dovecot.debug Info: /var/log/mail.log Warning: /var/log/mail.log Error: /var/log/mail.log Fatal: /var/log/mail.log REPORTING BUGS
Report bugs, including doveconf -n output, to the Dovecot Mailing List <dovecot@dovecot.org>. Information about reporting bugs is avail- able at: http://dovecot.org/bugreport.html SEE ALSO
