AWK multiple line fields sorting
I have a bash script which takes a log file with each record separated by a #. The records have multiple fields but field $1 is always the date and time. When the script is run it prints the record just fine from oldest to newest. I need to have records print out from newest first.
Here is the part of the code:
Code:
LOGFILE=`if [ $MONTH = "" ] && [ $uid = "" ] && [ $ROUTER = "" ] ; then
nawk 'BEGIN {FS="\n"}{RS="#"}{print $0;}' tmp/file.log
echo "$LOGFILE"

Here is a sample of the output:
Code:
03-31-2010 00:13:51
ab1234
SUBMITTED FROM URL: tool.cgi
show mem 
#
03-31-2010 00:15:35
bc1234
SUBMITTED FROM URL: tool.cgi
show mem 
sh ip access-list PROTECT_RE
#
03-31-2010 12:51:20
de1234
SUBMITTED FROM URL: ncg.cgi
vi aaa 
sho subscribers username 
#
03-31-2010 12:51:39
fg1234
SUBMITTED FROM URL: config_ncg.cgi
vi bbb 
sho subscribers username 
#

Needs to be printed out like this:
Code:
03-31-2010 12:51:39
fg1234
SUBMITTED FROM URL: config_ncg.cgi
vi bbb 
sho subscribers username 
#
03-31-2010 12:51:20
de1234
SUBMITTED FROM URL: ncg.cgi
vi aaa 
sho subscribers username 
#
03-31-2010 00:15:35
bc1234
SUBMITTED FROM URL: tool.cgi
show mem 
sh ip access-list PROTECT_RE
#
03-31-2010 00:13:51
ab1234
SUBMITTED FROM URL: tool.cgi
show mem 
#
