Shell Programming and Scripting

Hi,

I am having issue where I have to tail 3 log files continuously (forever) and while I am reading the files , parse them and shove the data into DB. I can do this with one file totally fine but how can I read 3 files at the same time? I am not really looking for code (but would be nice) but maybe a brief summary of the solution.

Btw: I am doing this in perl.

Any help is highly appreciated

Thx.

How about separate threads for each file? No idea about threading support in Perl though.

Not sure how to do it in perl but in shell scripting, I'd create a function that would read/parse the file:

Code:

parseFile () {
  fileNm=$1
  do something...
}

then I would call the function all at once in the script...

Code:

parseFile "file1" &
parseFile "file2" &
parseFile "file3" &

wait

etc.

I am looking at forking out multiple threads but don't know how well(or not) they will work for my problem.

Thx all.
