[chef] When run knife ssh error occurs only on one node, but therefore all ok.

[Vladimir Skubriev < >]

:~$ knife ssh "name:*example.lab" "sudo chef-client 2>&1 >/dev/null; if [ $? -eq 0 ]; then echo "OK"; else echo "BAD"; fi" -i ~/.ssh/id_rsa -x sysadmin --no-host-key-verify

backup.example.lab   sh: 1: Syntax error: Unterminated quoted string

backup.example.lab   sh: 1: Syntax error: Unterminated quoted string

titan.example.lab    OK

... OK

backup.example.lab OK

callisto.example.lab OK

Why this error occurs. Chef client updated on all machines to 11.8.2

Thank you very much answers.
