concurrent processes

We have a very large text file..contains almost 100K lines.
We want to process this file to generate another text file as per our data requirement.
As for now the parsing of data takes 20-25 mins each , for 100K lines.

the current script uses :
While Read Each Line
do parsing..
Done

We want to cut down the runtime from 20-25 mins to aorund 5-10 mins..
Hence it was decided that we must split the large input file into 10 files of 10K lines each and run the parsing script for all the 10 files at the same time..something like concurrent run..

How do I achieve this..I am new to the concept of concurrent runs ...
Please guide.

Concurrent writing to file

Hi I have a ksh that can have multiple instances running at the same time. The script (each instance) uses the SAME log file to write to. Should this cause a problem or is the ksh clever enough to queue write requests to the file? Thanks. GMMIKE (2 Replies)

KILLALL5(8)						Linux System Administrator's Manual					       KILLALL5(8)

NAME
killall5 -- send a signal to all processes. SYNOPSIS
killall5 -signalnumber [-o omitpid[,omitpid..]] [-o omitpid[,omitpid..]..] DESCRIPTION
killall5 is the SystemV killall command. It sends a signal to all processes except kernel threads and the processes in its own session, so it won't kill the shell that is running the script it was called from. Its primary (only) use is in the rc scripts found in the /etc/init.d directory. OPTIONS
-o omitpid Tells killall5 to omit processes with that process id. NOTES
killall5 can also be invoked as pidof, which is simply a (symbolic) link to the killall5 program. EXIT STATUS
The program return zero if it killed processes. It return 2 if no process were killed, and 1 if it was unable to find any processes (/proc/ is missing). SEE ALSO
halt(8), reboot(8), pidof(8) AUTHOR
