Using VIM to make acronyms?

Question

I have a file with lot of full names like .... ``` Light Machine Gun Statistical Analysis System etc ``` I want to capture the first character of every word in a line and want to make an acronym. For example Light Machine Gun would be LMG etc. I want to do it in VI editor record it as a macro and run it over the entire file.If anyone can help me that would be great? Thanks in advance.

Accepted Answer

Assuming one name per line and that the words are space separated, the following works:

```
%s/$\w$\w*\ */\1/g
```

If you also want to capitalize each letter, add an up-case flag (`\u`):

```
%s/$\w$\w* */\u\1/g
```

The "very magic" version (see `:help /magic`):

```
%s/\v(\w)\w*\s*/\u\1/g
```
