Shell Programming and Scripting

Hi All,
I have a small query. I have a file containing the following lines

File 1:
29-Jul-2011 [pattern1] GMT Static data requires update <Extraction should start here>
-----------
-----------
----------[pattern2]----------
-----------------------
-----------[pattern2] <should stop here>


Pattern1 will be time and pattern2 will be some userid:XYZ

I am trying to use following script, but it stops after the first occurrence of pattern2
awk ' /08:48:17/ { flag=1; } /gangii87/{ print $0; flag=0;} flag { print $0 }' log


Thanks

Hi All,
I finally got the logic by reading few older posts in this site
really this site is very helpful for the beginners like me

Here is working logic
awk '
BEGIN { start=0; skip=0; }
{
if(index($0, "08:48:22")> 0)
{start=1; print $0}
else
if(index($0, "sam@gmail.com")> 0) { if(skip==0) skip=1; else {skip=0; start=0; print$0 }}
else
if(start==1)
{
print $0
}
} ' log

Thanks
