[SOLVED] Date and time of a process when it was started

mario.almeida · 03-19-2010, 10:34 AM

Hi All,
Centos 5.4 64bit

Would like to know when a particular process was started.

1.

Quote:

ll -d /proc/4014/
dr-xr-xr-x 5 mysql mysql 0 Nov 28 07:34 /proc/4014/

2.

Quote:

ps -o pid,lstart -p 4014
PID STARTED
4014 Tue Nov 17 23:10:13 2009

1) Which one should I consider?
2) why do both have such a difference?

I'd tell the second one. The first one is just the modification time of the directory /proc/4014, that can change under some circumstances (e.g. create or rename files inside the directory).
