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)
