I know how to redirect stdout to a file: exec > foo.log echo test this will put the 'test' into the foo.log file. Now I want to redirect the output into the log file AND keep it on stdout i.e. it can be done trivially from outside the script: script | tee foo.log but I want to do declare it within the script itself I tried exec | tee foo.log but it didn't work.
