I have to transport a large file (470MB) between computers using a 128MB flash memory stick. Will simply using 'split' to break it into four sections and 'cat' to merge the sections on the other computer suffice ? Is there a better way ?

'split' and 'cat' will work. Presumably there is no connection between the two computers, and no CD burner available - (otherwise, you wouldn't have asked, right?)

You can compress the file with gzip - but it's probably not worth bothering as at best, it might save you one trip back and forth.

Use 'md5sum' to re-assure yourself that everything was copied and reassembled faithfully - I once had to download a couple of Gb of data in 20Mb chunks. There was a mistake in one of them that 'ls -l' didn't show up but 'md5sum' did.

Split, cat it is then I shall be using md5sum for integrity checking but the file in question is an iso, which is presumably compressed already. Thanks John.
