Hanging in pipe friendliness code on Bamboo CI machines

[kingfai]

Hi,

In our Bamboo environment, we are seeing slack ci hang while trying to read from /dev/stdin. I was able to work around this by piping a space into the slack cli command, but was wondering if there is a better solution.

Here are some logs:

16-Nov-2018 00:11:23	+ bash -x bin/slack chat send -x -tx 'testing this thing' -ch '#mcore_tools_basement'
16-Nov-2018 00:11:23	+++ dirname bin/slack
16-Nov-2018 00:11:23	++ cd bin
16-Nov-2018 00:11:23	++ pwd
16-Nov-2018 00:11:23	+ bindir=/Users/bambooagent/AgentHome/xml-data/build-dir/MTS-AS0-JOB1/bin
16-Nov-2018 00:11:23	+++ dirname bin/slack

16-Nov-2018 00:11:23	++ pwd
16-Nov-2018 00:11:23	+ etcdir=/Users/bambooagent/AgentHome/xml-data/build-dir/MTS-AS0-JOB1/bin

16-Nov-2018 00:11:23	+ shift
16-Nov-2018 00:11:23	+ case "${cmd}${1}" in
16-Nov-2018 00:11:23	+ sub=send
16-Nov-2018 00:11:23	+ shift
16-Nov-2018 00:11:23	+ case "${cmd}${sub}" in
16-Nov-2018 00:11:23	+ '[' -p /dev/stdin ']'
16-Nov-2018 00:11:23	++ cat
16-Nov-2018 00:31:55	Force Stop build feature is enabled for current plan. Either Bamboo has detected the build has hung or it has been manually stopped.

I ran into this issue six years later.

Thanks for tracking the cause down!
