Enter the following command in two windows: diffthis 4. if the content of a window is changed and vim does not automatically update the diff check, run the following command to update: diffupdate 5. locate the difference: [c jump to the previous difference] c jump to the next difference 6. jump between Windows: ctrl-w jump to the next window ctrl-w h jump to the left window ctrl-w l jump to the right window ctrl-w j jump to the bottom window ctrl-w k jump to the top of the window 7. merge document: dp applies the current document content of the difference point to another document (diff put) do to copy the content of another document of the difference point to the current document (diff get) personal note: space is not allowed: diffput, diffget. 8. when you expand and view the context and compare and merge files, you often need to combine the context to determine the final action to take. By default, Vimdiff displays the texts of 6 rows in the upper and lower directions for your reference. Other text lines are automatically folded. If you want to change the default number of rows in the context to three, you can set: set diffopt = context: 3 9. the simple folding command can be used to temporarily expand the same collapsed text line: zo (the lower-case letter 'L' can also be opened) (folding open, the letter z looks like a folding paper) and then you can use the following command to fold again: zc (folding close) zf create fold (use a number to show the number of rows from the current row to the bottom, for example, 3 J creates a fold that includes four rows) zm close all folding zr open all folding zE delete all folding zd delete current folding za if it is currently on close, if the current feature is disabled, zk is opened from zj to the start of the next fold to the end of the previous fold.
