Hi, in the documentation to diff is said under "Showing Differences Side by Side":
‘|’ The corresponding lines differ, and they are either both complete or both incomplete. What does _complete_ and _incomplete_ exactly mean? How is _differ_ defined? See also the examples in * https://askubuntu.com/questions/1302054/when-does-diff-use-in-a-side-by-side-diff and * https://askubuntu.com/questions/1105189/diff-side-by-side-output-with-incomplete-sign Thanks in advance Sigbert
