I am unable to view PDF's in VIFM with Evince (my pdf viewer of choice).  How does one do this?
Viewing PDF's in VIFM with Evince
vifm
You need to configure vifm to open .pdf files with Evince. In your ~/.vifm/vifmrc add the following lines:command evince evince *.{pdf} &filetype *.pdf evinceThe first defines a user command, the second sets the default program for specific filetypes.The default vifmrc (that should be installed to /usr/share/vifm/vifmrc) is very well commented and should provide all the documentation you need to get it up and running. The Arch wiki also has a vifm page that contains some helpful pointers and tips.
