jcs:printf() Function

jcs:printf('expression')

Generate formatted output text. Most standard printf formats are supported, in addition to some Junos OS–specific formats.

The %j1 operator emits the field only if the field was changed from the last time the function was run.

The %jc operator capitalizes the first letter of the format output.

The %jt{TAG} operator emits the tag if the field is not empty.
