(grcat) exit code zero despite previous pipe command returning non-zero about grc HOT 5 OPEN

As a workaround, you can use $PIPESTATUS:

$ true | grcat ../.grc/conf.ping ; echo $PIPESTATUS
0
$ false | grcat ../.grc/conf.ping ; echo $PIPESTATUS
1

E.g.:

mvn compile | grcat ~/conf.mvn
[ $PIPESTATUS -eq 0 ] && sh deploy_my_app.sh

This is actually a valid concern - however, note that cat would eat the exit status too, so it is a matter of how much compatibility with cat we want to maintain.

In addition to $PIPESTATUS, you might use set -o pipefail if your shell is bash.

Thanks for the suggestion. Feel free to close the ticket.

Pipefail also works in zsh 5.0.8, thankfully for me.

foobar | cat && echo "Succeeded wrongly"
zsh: command not found: foobar
Succeeded wrongly


set -o pipefail; foobar | cat || echo "failed correctly"
zsh: command not found: foobar
failed correctly

I would suggest you maintain 100% compatibility with cat (well, minus the colourizing 👀).

In this manner, it's a drop-in replacement and scripts do not need to be reconfigured.
