From 056d3c8e6481088b8e5d9791d8c1762a3c8d1a83 Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Sun, 22 Jul 2018 17:57:13 +0200 Subject: Add output truncation flag This commit adds a "truncate" flag that can be added to a service description between the "tty" keyword and the path string. If the flag is set, the output file is truncated to 0 after opening. This probably requires some remodeling in the future as the tty keyword no longer deals with just tty devices.
