ipmi-sensor-discovery.sh: 47: set: Illegal option -o pipefail

[xenadmin]

Hallo, discovered your work on share.zabbix.com. I downloaded the script and tried to run if from shell, but it fails immediately. Any idea why this happens? Thank you!

EDIT: I'm on Debian 9 Stretch amd64 with Zabbix 3.4.x If I comment out line 47 the script seems to work.

In what shell (and version) are you starting this script?

echo "Default shell is: ${SHELL}"
echo "Current shell is: ${0}"

[xenadmin]

root@zabprox:/usr/lib/zabbix/externalscripts# echo "Default shell is: ${SHELL}" Default shell is: /bin/bash root@zabprox:/usr/lib/zabbix/externalscripts# echo "Current shell is: ${0}" Current shell is: -bash

OK, at least root is using bash as the default shell, which is supposed to support -o pipefail. The script uses #!/bin/bash as the shebang, which should execute the script with bash anyway.

Can you please try the following steps:

1. Run set -o pipefail from a bash prompt and check if you also get the Illegal option error message
2. Add the following lines to the script (right after the comment header) and let it execute by the Zabbix-Server/Proxy (as the zabbix user)

echo "0:            ${0}"                      > /tmp/debug.out
echo "SHELL:        ${SHELL}"                 >> /tmp/debug.out
echo "proc-exe:     $(readlink /proc/$$/exe)" >> /tmp/debug.out
echo "SHELLOPTS:    ${SHELLOPTS}"             >> /tmp/debug.out
echo "BASHOPTS:     ${BASHOPTS}"              >> /tmp/debug.out
echo "BASH_VERSION: ${BASH_VERSION}"          >> /tmp/debug.out

3. Post the output of /tmp/debug.out

Sorry, I forgot you! I will update this comment tomorrow! Keep up the great work, I will come back to you and your IPMI collection asap!

@xenadmin is this issue still relevant to you? Otherwise I would close it within the next days.

Thanks for your feedback.

I think this can be closed. I switched over to the official SNMP templates (https://www.zabbix.com/documentation/4.0/manual/introduction/whatsnew400#new_templates) and adjusted them to my needs. Many thanks for your help! If I should ever take a look again at IPMI, I will remember you!
