c8y devices assert exists
Assert existance of a device
Synopsis​
Assert that a device exists or not and pass input untouched
If the assertion is true, then the input value (stdin or an explicit argument value) will be passed untouched to stdout. This is useful if you want to filter a list of managed objects by whether they exist or not in the platform, and use the results in some downstream command (in the pipeline)
By default, a failed assertion will not set the exit code to a non-zero value. If you want a non-zero exit code in such as case then use the --strict option.
c8y devices assert exists [flags]
Examples​
$ c8y devices assert exists --id 1234
# => 1234 (if the ID exists)
# => <no response> (if the ID does not exist)
# Assert the managed object exists
$ echo "1111" | c8y devices assert exists
# Pass the piped input only on if the ids exists as a managed object
$ echo -e "1111\n2222" | c8y devices assert exists --not
# Only select the managed object ids which do not exist
$ echo 1 | c8y devices assert exists --strict
# Return non-zero exit code if a managed object id=1 does not exist
Options​
--device strings The ManagedObject which is the source of this event. (accepts pipeline)
--duration string Timeout duration. i.e. 30s or 1m (1 minute) (default "30s")
