SED variable substitution
Hi Chaps...

I have a log file as below:-

Code:
01 Oct 2009 12:57:56 DEBUG [pollingThread]:

01 Oct 2009 12:14:21 DEBUG [pollingThread]:.....

06 Oct 2009 01:23:11 DEBUG [pollingThread]:....

.06 Oct 2009 12:53:46 DEBUG [pollingThread]:....

Now I have to cut all the logs whcih are created today and do some basic operation...

now considering my end string time stamp will vary I have cut the time stamp of last line to a variable...

and start string can be taken as date as I have date in my log...

for cutting the log file i have written ..
Code:
 
#!/bin/bash
 
. ~/.profile
 
date_var=`date "+%d %h %Y"`
#date_var='01 Oct 2009'
time_stamp=`tail -1 Interface.log | cut -f4 -d " "`
end_string="$date_var $time_stamp"
sed '/^'$date_var'/,/^'$end_string'/!d' Interface.log | sed '/^#/d' | sed '$d' >> current_day_log.txt

when I run above script I get error as sed: command garbled: /^06

looks like there is a problem while substituting the varibale in SED...can anybody point out what I am doing wrong here...

Many Thanks in advance...
