From: Philippe Proulx Date: Wed, 15 Mar 2017 00:48:18 +0000 (-0400) Subject: doc/man: add typical `$` and `#` prompts to command lines X-Git-Tag: v2.8.3~5 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=ab4c0f44fad08a6766e03cecac56f87e9283b6c2;p=lttng-ust.git doc/man: add typical `$` and `#` prompts to command lines It is more instinctive for the typical reader to immediately recognize command lines when they start with the classic prompts. On the online version of the man pages, those prompts are treated specially to make them non-selectable. This makes it possible to copy multiple command lines at once (without copying the prompts) and to paste them to your shell.
