title: Execute Macro in All Buffers
tags: vim macro

```
:argdo execute "normal @a"
```

# Example: prepend license
Record a macro `a` that does
```
:0r license.txt
:w
```
then
```
:args *.c
```
and either
```
:argdo execute "normal @a"
```
or
```
:argdo normal @a
```
and the macro will be executed for each file.
The `execute` variant allows us to use the `|` to do
```
:argdo execute "normal @a" | write
```
