(3) More editing commands
These editing commands are very flexible and basically consist of commands and scopes. For example, what is the best practice in DW? The combination of nbsp; D and range W indicates that a word D (elete) W (ORD) is deleted ).
The command list is as follows:
D. Delete)
Y replication (Yank)
P placement (Put)
C Change)
The range can be:
E? BR> W cursor position to the first letter of the next word
B. Place the cursor on the first letter of the last word.
$ Move the cursor to the last letter in the column
0 cursor position to the first letter in the column
) Place the cursor to the first letter in the next sentence.
(The cursor is located at the first letter in the sentence.
} Move the cursor to the last letter of the paragraph
{Place the cursor in the first letter of the paragraph
To be honest, it is a little artistic to combine these commands to edit files. In any case, they provide more text editing capabilities. It is worth noting that the deletion and replication will put the content within the specified range in the temporary storage area, and then the instruction P can be used to paste it to other places, this is how VI processes copying and moving segments.
Some VI versions, such as Elvis for Linux, can greatly simplify this instruction. If you take a look at these editing commands, you will find that the problem is actually a bit complicated by the fixed range method. In fact, there are only four commands. Command V is very easy to use. As long as you press the V key, the position of the cursor will be reversed. Then, you can move the cursor to set the range, and then directly edit the command. For the entire column operation, VI also provides more convenient editing instructions. As mentioned above, the command DD for deleting the entire text column is one of them. CC can modify the entire text column, while YY is to copy the entire text column; command D deletes all text from the cursor until the end of the column.
(4) file operation commands
File Operation commands start with:, which is a little different from editing commands.
: Q end editing (quit)
: Q! You must discard edited files without archiving them.
: W: Save the file (write) and add the file name to be archived.
: WQ indicates that the archive is removed.
ZZ functions are the same as: WQ.
Same as: WQ
