Use colordiff in side-by-side mode, and with automatic column widths.
Barely worth posting because it is so simple, but I use it literally all the time. I was always frustrated by the limitations that a non-gui environment imposes on diff'ing files.

Get information of volume labels of bitlocker volumes, even if they are encrypted and locked (no access to filesystem, no password provided).
