The logger(1) tool in your system, /usr/bin/logger, standardized in IEEE Std 1003.2 (“POSIX.2”), has many different implementations. For Linux users the most common one is part of the util-linux package. I’ve always considered this one of those weird Linux:isms. The logger tool is closely tied to the system log daemon, so in the sysklogd project we ship our own implementation of logger. Our implementation is derived from the Finit project’s logit tool.
