When I'm trying to open a pdf file by using evince command it showing like this
** (evince:31541): WARNING **: Could not open X display
No protocol specified
error: XDG_RUNTIME_DIR not set in the environment.
Cannot parse arguments: Cannot open display:
Please give me the solution to work with evince.
evince is an editor designed to run under a GUI (man evince says The Evince Document Viewer application for the GNOME desktop environment), and you seem to be running it in a non-GUI environment.
Either run evince in a graphical environment, or, if you're accessing this system via ssh (and have a local X server), check man ssh and use ssh -X ... to initiate your session.
