It can be used to edit all kinds of plain text. !date": that replaced a line, while ":read !date" will insert a line. The word it is searching for is "frame_counter". This continues until you type . Go to that window (using Ctrl-W w) and the type this command: Ctrl-W K. This uses the uppercase letter K. What happens is that the window is moved to the very top. That is a very good way to see where the variable is used, without the need to type commands. Fortunately Ctrl-F is Forward and Ctrl-B is Backward, that's easy to remember. Type ":help subject" to get help on a specific subject. For example, to delete from halfway one word to halfway another word: When doing this you don't really have to count how many times you have to press "l" to end up in the right position. You can also do it the other way around. Edit the "main.c" file, then make a split and show the differences: The ":vertical" command is used to make the window split vertically. This either removes differences or adds new ones. The range is always placed before the command. Finally you use an operator to do something with the selected sentences. Otherwise, it becomes a filter command, which is explained later on this page. Then you can specify an offset. There is a slight error in the above command: If the title of the next chapter had included "grey" it would be replaced as well. Now you need to save the file under a new name. Suppose you have recorded a command to change a word to register c. It works properly, but you would like to add a search for the next word to change. Another option that matters here is 'backupdir'. The 'wrapscan' option is on by default, thus searching wraps around the end of the file. Another example: You want to change the word "four" to "five". To read the contents of the current directory into the file, use the following commands. For example, there are other ways to delete pieces of text. This means that vim knows this is not the file you started editing. To search for a string, use the "/string" command. Suppose you are editing a chapter in a book, and want to replace all occurrences of "grey" with "gray". To verify whether you have Vim installed, use this command: If you get nothing in return, you don't have Vim installed. For example: To sort this list, filter the text through the external sort command: This goes to the first line, where "OBJS" is the first thing in the line. This is called "exclusive" when the character isn't included and "inclusive" when it is. Unexpectedly, while "D" deletes from the cursor to the end of the line, "Y" works like "yy", it yanks the whole line. There are 26 letters, and many more commands. But this command is allowed: The file "patch" will be put above the first line of the file. Thus you can make a choice whether you do or don't want to append text to a short line. It cannot be simpler than this, can it?Cat becomes a powerful command when used with its options. The a register now contains all those lines, in the order you yanked them. In this next example, let's change the text "Last, First" to "First Last". This is one of the ways vim is different than vi; in vi, pressing u twice undoes the undo itself. If you want to see the list of files, use this command: This is short for "arguments". If you have selected some text in Visual mode, and discover that you need to change the other end of the selection, use the "o" command. Suppose the cursor is somewhere in the first of these two lines: If you now use the "o" command and type new text: Then type to return to normal mode. Then type g Ctrl-G. Making the same selection by moving the cursor to the end of the longest line with other movement commands will not have the same result. There is nothing special about using "s" for start and "e" for end, they are just easy to remember. This can be done with the line number zero. After a while you will find that black&white text slows you down! The cursor position when last editing the file. Otherwise, one out of the following four options may be used to choose one or more files to be edited. Thus to search for the word "the" only: This does not match "there" or "soothe".

Delete word under the cursor (including white space). If you want syntax highlighting only when the terminal supports colors, you can put this in your vimrc file: If you want syntax highlighting only in the GUI version, put the ":syntax enable" command in your gvimrc file. The ":version" command mentions the name of the "user vimrc file" vim looks for. The space before "human" isn't deleted. There is a special way to start vim, which shows the differences between two files. Similarly, "/^Chapter/" is used to search forward for the start of the next chapter. The ":saveas" command can be used for this: vim will write the file under the given name, and edit that file. That's: a number {height}, Ctrl-W and then an underscore. Even when you use a count to make them move the cursor quite a long way away. Move the cursor to the beginning of the first line, for example, and type xxxxxxx (seven x's) to delete "This is". Both of these commands take a count and increase or decrease the window size by that many lines. For example, if you want vim to always start with the 'incsearch' option on, add this line you your vimrc file: For this new line to take effect you need to exit vim and start it again.

To remove whitespace at the end of every line, execute the following command: The line range "%" is used, thus this works on the whole file. Also, there are keyboards which do not have arrow keys, or which locate them in unusual places; therefore, knowing the use of the hjkl keys helps in those situations. The Ctrl-W w command can be used to jump between the windows. To make it write only the current line into a file: The first line always has number one. The "R" command automatically extends the line if it runs out of characters to replace. But it can't know about what another program has written. These characters are not really there. vim is clever enough to know that you might have wanted to expand the short name of the option into the long name. This will not do the right thing if your file also contains "thirtyfour". Take these two lines: Move the cursor to the first line and press "J": The "u" command undoes the last edit. The Unix command wc counts words. Thus the substitution is done in every line in the file. But actually, it only writes files with changes.

It works with "v" and "V" selection in exactly the same way. command. vim is an extensive program, and so it has a lot of options! vim installs with a built-in tutorial system called the vimtutor to help you learn vim commands. The register name must be between a and z. This is called a range. The vim command will automagically detect the type of file and load the right syntax highlighting.

It's known for being fast and efficient, in part because it's a small application that can run in a terminal (although it also has a graphical interface), but mostly because it can be controlled entirely with the keyboard with no need for menus or a mouse. This must come just before the yank command. It should show something like "(2 of 3)". This command is limited by the amount of text that is there; so if there is less than a shift amount of whitespace available, it removes what it can. Then it moves to its match: To move to a specific line, use the "G" command. Thus you can use this to move through a paragraph, much faster than using "l". Example: Notice that "yw" includes the white space after a word. It would be replaced with "thirty4". The two windows allow you to view two parts of the same file. The ":grep" command uses the external commands grep (on Unix) or findstr (on Windows). If the command doesn't split a window, it works unmodified. This works as follows: "x" deletes the character e and places it in a register. Instead of putting plugins directly into the plugin/ directory, you may better organize them by putting them into subdirectories under plugin/. To only find words that end in "the" use: The "\>" notation is a special marker that only matches at the end of a word.
