ps -ef &
ls &

and now i am run this file and redirect the output to a file (say output.log)
./test.sh > output.log

Now the result stored in the file is not like that first ps -ef and than ls
it mixed the output of both command

Now help me so thats i can store the result in the file only one after another

Thanks
