About

It is possible to create multiple output files as a result of XSL processing in XSLT 2 with tag xsl:result-document. This is usefull for example when some large database is available as a single XML document from which we need to extract only certain parts and/or modify it. This particular example takes export of accounts from the Waveset Identity Management system, filters them, modifies them and saves them in a separate file per account. This principle might be however usefull in many other cases.

This work is largely based on an example from IBM developer works

It is possible to redirect some input to TTY device by standard IO redirection.

echo ahoj > /dev/tty1

Such redirection will however end in the output buffer of the TTY device so the characters will be ghosts - visible on the terminal, but not effective. It is, in fact, not possible by standard tools to redirect input to terminal as if it is a real input from keyboard.
