Cygwin script log redirection not working well
I have a simple script which will send a curl request and redirect the output to a log file.

Code:
for i in {1..20}
do
 curl google.com -is >>log.log &
 echo "request # $i" >> log.log
done

After it completes the execution, if I run the following command I should see 20 lines because I am printing it in the loop.
Code:
cat log.log|grep request|wc -l

But I see 1 or 2 lines and all my log is messed up. I know that I am sending curl command to the background so the log will be mixed up. But I should see 20 "request" when I grep the log.

The same script works fine in my ubuntu. Also it works fine in my friends cygwin. I uninstalled cygwin and installed it back but no change. I guess it is something with my windows configuration? Anyone know why it is happening?

My messed up log
Code:
