graff,
Presumably, the files need to be appended in the order encountered. Part of the long story unmentioned is a lot of guarded responses to my inquiries for additional information. A cut | sort | uniq might not be a bad idea to pre-process the file to get a list of unique file names though.

## let's suppose the file names are in column 3 of "table.txt":
perl -pe 's/^/$.,/' table.txt | sort -t , -k 4,4 -k 1,1n | cut -f2- -d
+, | splitter.pl
where "splitter.pl" is a version of your suggested script that assumes lines are pre-sorted by output file name -- so it really needs only one output file handle open at any one time. By pre-pending the original line numbers before sorting, and using the line numbers as a secondary sort field, the (presumably) intended result is achieved.
(update: if the original table has file names in column 3, and a perl script prepends a line number to each line, then the primary sort column has to be 4, not 3.) | [reply]

graff,
I wonder if all java programmers are this cagey/evasive about describing their problem sets
I doubt it. There are people in all trades and positions that like to keep what they do a secret in fear that if people know then their importance and value might be diminished. Since my job title has nothing to do with programming, I am assuming solving such a "simple" task with an "inferior" language would be a huge eyesore. Anyway - it is the Java Developer's problem - not mine. I just wanted to present the problem here so that if there was an superior approach that I was missing I could learn it.
