okay bestie, this is the c8y(1) manual page for c8y-devices-assert-exists β¨ and it's literally here to assert that a device exists (or doesn't) and then pass your input along untouched. no cap. π«Ά
π NAME π
c8y-devices-assert-exists β assert existence of a device π
β¨ SYNOPSIS β¨
c8y devices assert exists [flags]
π¦ DESCRIPTION π¦
okay so this command does a vibe check on whether a device exists or not, and then passes the input untouched π
If the assertion is true, then the input value (from 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). iykyk π
β οΈ 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 that case, use the --strict option. periodt.

π₯ EXAMPLE π₯
$ 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
