Shell script

Hello,

How do I go about adding to a shell script so that its' STDOUT and STDERR will both be seen on screen (as normal) and ALSO sent to a file?

Thanks,
Jason

that'll be the "tee" command.

echo test | tee blah

should echo the word "test" but also write to the file called "blah". note that that will by default only cover stdout, not stderr too, so you'd need to redirect stderr to stdout beforehand:

echo 2>&1 test | tee blah

otherwise the blah file would only include stdout, not the error stream.
