I want to join these log just into one file for each program, I can't file the configuration for the glog ,any helps?

Answer 1

If you want to change the name of log files, you may need to call SetLogDestination():

google::SetLogDestination(google::INFO, "/var/tmp/another_destination.INFO");

Answer 2

From release 0.5 on May 8, 2021

Allow a log file to be simply named "foobar.log" with no appended string #124

google::SetLogDestination(google::INFO, "/var/tmp/another_destination.INFO"); FLAGS_timestamp_in_logfile_name = false;
