Write to Mac OS X Console logs from shell script or command line [closed]
syslog -s -l error "message to send"will log the message as something like
May 29 17:15:09 hostname syslog[22316]: message to sendYou can customize things by using -k, which expects a list of alternating keys and values, for example
syslog -s -k Facility com.apple.console \ Level Error \ Sender MyScript \ Message "script says hello"would produce
May 29 17:22:21 hostname MyScript[22343]: script says hello(setting the Facility to com.apple.console makes it a "console" message, equivalent to stdout output from a double-clicked bundled application, and retrievable using syslog -C)
