On: The Greatest Regex Trick Ever (2014)

[bbarnett]

In bash, you can get the rc of piped things, the var eludes me while walking..

[dylan604 → bbarnett]

${PIPESTATUS[@]} for a space delimited list of all exit codes, or replace @ with the position in the pipe chain of the specific command you want.

ps auxwww | grep banana | grep -v grep && echo ${PIPESTATUS[1]}

type of thing

[joombaga → bbarnett]

You can also set -o pipefail. The first non-zero exit code is returned if there is one.
