I've seen and used this syntax: $ prog < input.file > output.file (but can't remember when or with which prog!) Can 'prog' be given options in such a syntax? $ prog --verbose < input.file > output.file ? I'd like to see how it works in the source so if anyone knows of a program that can do this (and which is written in C), it would be handy! Also any tips on enabling such input in a C program - I know how to do it in Perl, but in C is it just a case of opening STDIN with a filehandle? Are there any special considerations compared to just opening a file that already exists on the filesystem? (I'm using getline as a GNU extension to remove the need for a fixed size char* buffer to prevent buffer overflows). -- Neil Williams ============= http://www.data-freedom.org/ http://www.nosoftwarepatents.com/ http://www.linux.codehelp.co.uk/
