By concurrency, I assume you are referring to simultaneous execution of processes. Unless you are on a multi-processor system the real concurrent execution of any processes is not possible.

In your case, you could try something like,

split the files such that there are 10 10K files
run each of the script individually as a background process
<script> for the first file with 10K & ( in background mode)

run through the loop for all the files

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
