Tailing logs from different files into one single file
Hi
Please help me in finding a solution for tailing multiple log files and writing all of them into one common file.
I have 4 log files with same name in 4 different folders.
Whenever I post a Request - any one of these 4 log files gets updated with some log detail in the below format :
blah|blah|blah|blah|blah
ex:
Logging can happen in any of the above 4 logfile.log instances each time a request is sent to the Server.
I check if logging happens or not by tailing all the above 4 instances in 4 different windows which is very ineffective.
I want to make this simple by writing some script that will look up if any of the log files get updated whenever a request is sent & then write that line into one common file.
ex :
I want to tail only that common file each time to capture my Logs.

That is, I like to tail a log and when a certain keyword appears I then want my script to play an audio file for example.
Any ideas??

logsave
LOGSAVE(8) System Manager's Manual LOGSAVE(8)NAME
logsave - save the output of a command in a logfile
SYNOPSIS
logsave [ -asv ] logfile cmd_prog [ ... ]
DESCRIPTION
The logsave program will execute cmd_prog with the specified argument(s), and save a copy of its output to logfile. If the containing
directory for logfile does not exist, logsave will accumulate the output in memory until it can be written out. A copy of the output will
also be written to standard output.
If cmd_prog is a single hyphen ('-'), then instead of executing a program, logsave will take its input from standard input and save it in
logfile
logsave is useful for saving the output of initial boot scripts until the /var partition is mounted, so the output can be written to
/var/log.
OPTIONS -a This option will cause the output to be appended to logfile, instead of replacing its current contents.
-s This option will cause logsave to skip writing to the log file text which is bracketed with a control-A (ASCII 001 or Start of
Header) and control-B (ASCII 002 or Start of Text). This allows progress bar information to be visible to the user on the console,
while not being written to the log file.
-v This option will make logsave to be more verbose in its output to the user.
