i want to call a command in a shell script then redirect stderr to a pipe to tee with stdout still going to the screen.

i tried

Code:

but it interpritaded 2 as an aditional argument

i believe you should replace "2|" with "2>"

ah got it... replace the | withj > and surround the tee command in backticks

command 2>&1 | tee sample.log

i think this will help u. For eg. ls -w 2>&1 | tee sample.log

The above command 'ls' does not have '-w' option, will throw error on screen & as well as stores in sample.log
