tee and exit status

Question

is there an alternative to \"tee\" which captures STDOUT/STDERR of the command being executed and exits with the same exit status as the processed command. Something as followin

Answer 1

This works with bash:

(
  set -o pipefail
  mycommand --foo --bar | tee some.log
)

The parentheses are there to limit the effect of pipefail to just the one command.

From the bash(1) man page:

The return status of a pipeline is the exit status of the last command, unless the pipefail option is enabled. If pipefail is enabled, the pipeline's return status is the value of the last (rightmost) command to exit with a non-zero status, or zero if all commands exit successfully.
