How to redirect stderr and stdout to a file

sushantnirwan · #1 (**permalink**) 08-28-2008

Hi friends
I am facing one problem while redirecting the out of the stderr and stdout to a file
let example my problem with a simple example
I have a file (say test.sh)in which i run 2 command in the background

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

its because when you run them in background they will run simultaniously..

Run your whole shell script in the background; not the individual commands within the shell script.
