Thanks for the info, and the code snippet. I've got one question though - I just thought of using the UNIX 'cat' command to splice together the two halves of the file (outputting stuff at the 'insertion point' to a different file, coming back to insert the stuff in the original file, and then using 'cat' to combine the two files.

I'm going to be working with huge text files, though, so efficiency is a Very Big Deal. Do you know if using a system call to 'cat' will be less efficient than creating the temp file etc? I haven't found a comparable perl function.

Thanks.
