Since you're specifying 3 digit file sequence numbers, I assume you expect that you'll be producing more than a hundred files with this script. There is a good chance that awk will run out of file descriptors if you keep all of them open. You might want to consider something like:
If there are existing split.xxx.txt files when you start this script do you really want to append data to them, or do you want to remove any data that was there before and just keep what you find in the current input file?
If you want to append to existing files, the script above should work.
If you want to replace data instead of appending data, change:
to:
As always, if you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk, /usr/xpg6/bin/awk, or nawk.
