Hey all,
I just tried loading a 2MB file in gedit and it silently died on me. I was wondering if anything might appear in a log file that might help me diagnose this: I checked syslog
and found out it segfaulted. While doing this I realised that I don't really know anything about how logging is organised on *nix machines.
All I know at the mo is
Logs are typically stored in
/var/log/
... is there anywhere else that I should know about?I'm familiar with application specific logs, such as apache's.
I understand that
dmesg
is the bootup log, andsyslog
is a general system log... is that right?
So would someone mind taking me through the most useful logs? Are the two logs I mention in the final point the only general logs? And what are the funky numbers at the start of lines in dmesg
? Seconds since startup?
Please include anything in your answers that you think would improve my understanding here and help me track down anomalies!
TIA
Andy
