Describe the bug
sh: 1: [: missing ]

I dont understand the cause of this.

Date: Wed, 22 Nov 2023 07:36:01 +1000 (AEST)
From: Cron Daemon <root@betlognuc.lan>
To: root@betlognuc.lan
Subject: Cron <munin@betlognuc> if [ -x /usr/bin/munin-cron ]; then /usr/bin/munin-cron; fi

sh: 1: [: missing ]
sh: 1: [: missing ]

The logic seems to be functional:

user@betlognuc:~$ which munin-cron
/usr/bin/munin-cron
user@betlognuc:~$ [ -x /usr/bin/munin-cron ] && echo yes
yes
user@betlognuc:~$ [[ -x /usr/bin/munin-cron ]] && echo yes
yes
user@betlognuc:~$  if [ -x /usr/bin/munin-cron ]; then echo yes;fi
yes

Try with test instead like

if test -x /usr/bin/munin-cron; then /usr/bin/munin-cron; fi

Or maybe you need to quote the whole line that you have in the munin config. Can you add your munin config where you're trying to have this logic, to the issue?

I didn't know where it was coming from. I should have know to check munin.conf again, i pretty much have it permanently open.
The problem was a trailing backslash.
