I guess this comment sparked research and `tail` actually does what I need to
do.
qx{cat X > out.txt; tail --lines=+2 Y Z >> out.txt};
Maybe I'll just head out to the command line it just won't be portable. There
will be about 300 CSV files to merge in the process but I only need the header
row on the first one.
But, performance is not really as big of a concern as memory for this process.
Thanks,
Mike _______________________________________________
