It depends on whether you use MS-DOS or a better OS ;) DOS was the last operating system which I know of which used temporary files for pipes. Every other system uses in-memory FIFOs (first-in-first-out). BTW: your last example "type | sort | uniq" can be shortened to "type | sort -u" Hope this helps, Florian Philipp
