Hi,

I want to extract block of data from flat file.
the data will be like this

start of log
One
two
three
end of log

i want all data between start of log to end of log i.e One
two
three to be copied to another file.
This particular block may appear multiple times in same file. I want all the blocks to be directed to new file.

x=`grep -n "start of log" text | cut -d ":" -f1`
y=`grep -n "end of log" text | cut -d ":" -f1`
a=`echo ${x} + 1 | bc`
b=`echo ${y} -1 | bc`
