Hi list,
apologies for the keyword overload ;-)
I have a plan9port mkfile using Rc (MKSHELL=$PLAN9/bin/rc), a recipe
contains pipeline: FOO_COMMAND | BAR_COMMAND.
What is the correct way of detecting failure exit status of
FOO_COMMAND (a networked operation) and ignoring exit status of
BAR_COMMAND?
the best i came up with is very ugly:
target: prereq
FOO_COMMAND | BAR_COMMAND
st = $status
if (~ $st ?* ^ '|' ^ *) {
echo FOO_COMMAND failed
exit 3 }
seems the | in pattern has to be quoted, otherwise is interpreted as
pipe operator.
regards,
