![]() ![]() ![]() The x command exits, after writing any changes to the file. ![]() In many (most) ex implementations you can also use an additional -c option, like so: ex -sc '%s/\(\.com\).*/\1/' -c x file.txt The vertical bar separates sequential commands to be executed. In this case from ".com" to the end of the line is replaced with just ".com". ![]() It is commonly used in vi and has essentially identical features to the s command of sed, though some of the advanced regex features may vary by implementation. S is the substitute command that you are likely familiar with already. % is an address specifier equivalent to 1,$-it means that the following command is applied to all lines of the buffer. c specifies the command to execute once the file ( file.txt, in this case) is opened in a buffer. s enables silent mode to prepare ex for batch use. :bufdo) and are not defined in the POSIX specifications for ex, but those specifications allow for a truly astonishing degree of power and flexibility in non-visual text editing (whether interactive or automated). Of course many of the more advanced or "fancy" commands you can execute this way are Vim extensions (e.g. If you've used vi and if you've ever typed a command that begins with a colon : you've used an ex command. exclusive motion.The best tool for non-interactive in-place file editing is ex. In the Vim documentation, for each motion description, it provides its nature.įor instance here is the excerpt for the 0 motion:Ġ To the first character of the line. How to tell a motion is exclusive or inclusive? Now you should end up with: Yesterday was Tuesday Now, type the sequence: cv0Yesterday was and then Escape. Operator, this can be applied to other operations too, such as change ( c) orīelow, is the use case of willing to change Today is: Tuesday to Yesterday was Tuesday, starting with the text snippet and the cursor positioned on the :: Today isTuesday Since the behaviour comes from the nature of the motion rather than the Now applying one of these commands to the first text snippets produces the Here are the inclusive equivalent of the above presented commands: Motion (and vice-versa), using the v modifier. Hopefully, Vim has a mean to turn an exclusive motion into an inclusive In our example the "last character towards the end of the buffer" is the :, WhenĮxclusive, the last character towards the end of the buffer is not included. Start and end position of the motion are included in the operation. The reason behind this, is that the motions used above, ^, | and 0 areĪ character motion is either inclusive or exclusive. Thisĭoes not meet the original expectation. Now you want to delete backward until the beginning of the line.įirst things that come in mind are usually the commands d^, d| or d0.īut unfortunately, here is what you are left out with: TuesdayĪs you can see the character previously under the cursor is still present. Let's say you have the following text snippet, and that you are in normal mode: Today isTuesday Note: In the below text snippets, the square brackets symbolise the cursor, and theĬharacter inside these brackets, the character being under the cursor. This single character that may make a difference. Such as blogs, books, screencasts, forums.
