Hi all, i am a students that is learn in java linux programming.,

i want to make program that processing entry in log on real time...

I have try to pass "tail -f -n 1 /var/log/messages" command
from .runtime().exec and process the output,,

description of the algo is like this

-
passed to exec()
-read output
-if not same as previous value procces it

sorry for my bad description, because i write this from my phone

but sometimes it loose some entry to procces, maybe it occur when proccesing another entry is added by system...

Please let me know if you have any solution for the reading problem...

sorry for my bad english...
I am very appreciate for any reply...

Wouldn't it be a far better idea to read the log file with Java's own libraries, instead of relying on the system having a certain shell and utilities installed?

which library i should use? And how it works?

Use Google:

wait, that is standard i/o class in java,, i have use it, it works like periodicly read from start of the log and save the last point of entry by time in log entry,, but the same problem still occur because sometimes , entry on log are added by system in seconds,, so the reading is fail...

thank you, but i have found solution for my problem, i am using class tailer from apache, it works prety good...

Then mark the thread as solved (unless you feel that you still didn't get a good solution).
