Joining Big Files

[mosscliffe]

I have 4 text files each approx 50mb.

I need to join these into one large text file.

I only need to do this very occasionally, as the problem has occurred
because of upload limitations.

Bearing in mind filesize and memory useage, would I be better reading
every line in every file and writing each line to the output file or
is there someway I could execute some shell command.

I am working on a hosted website with no direct telnet or similar
access.

I would appreciate any tips, best code, as I do not want to break
anything on the website.
