 == The Journalctl command - a quick reference [http://www.freedesktop.org/software/systemd/man/journalctl.html]==
-=== Add user to adm group, gives <user> full use of the journalctl command: ===
+ Note: Add user to adm group, gives <user> full use
+ of the journalctl command, so you don't need to use sudo
+ (swap "handy" for your username):
+ # usermod -a -G adm handy
+ Note2: You can pipe the output of journalctl to a file or
+ to a text display tool like "More" or "Less", as follows:
+ $ journalctl -b -p err|less
+ This gives you a means of avoiding the truncation of output
+ which some system' displays may experience.
+ I use a ~/.bashrc alias to make this easy:
+ alias errors="journalctl -b -p err|less"
+ When I type "errors" in the Terminal, all errors or worse,
+ since the last boot are displayed in the Terminal text
+ display tool "Less" & no lines are truncated.
+ Type Q to close "less".
