Question

Is there a way to stop the Geth console from printing syncing information?

I start Geth with geth console.

Actually, I do not want to see all that syncing information constantly. Can I turn it off somehow without using geth attach?

Answer 1

Yes you can do that. Take a look at LOGGING AND DEBUGGING OPTIONS

Either you can set geth --verbosity "0" or you can log them into a file geth --verbosity 5 console 2>> /path/to/logfile

---

LOGGING AND DEBUGGING OPTIONS:
  --metrics         Enable metrics collection and reporting
  --verbosity "3"               Logging verbosity: 0-6 (0=silent, 1=error, 2=warn, 3=info, 4=core, 5=debug, 6=debug detail)
  --vmodule ""                  Per-module verbosity: comma-separated list of <module>=<level>, where <module> is file literal or a glog pattern
  --backtrace ":0"              Request a stack trace at a specific logging statement (e.g. "block.go:271")
  --pprof                       Enable the profiling server on localhost
  --pprofport "6060"            Profile server listening port
  --memprofilerate "524288" Turn on memory profiling with the given rate
  --blockprofilerate "0"    Turn on block profiling with the given rate
  --cpuprofile          Write CPU profile to the given file
  --trace           Write execution trace to the given file

Answer 2

you can also change the verbosity in the client with debug.verbosity(x) where x is the level you want.
