Vim: Essential Commands & Quick Reference Card

References

Here are some practical commands that I don't always remember:

Replace text in the current line:

1
:s/original/destination/g

Replace text in the entire document:

1
:%s/original/destination/g

Remove trailing spaces and tabs at the end of lines:

1
:%s/\s\+$//

Here's also the Quick Reference Card and the same thing but in French :-).

The Functions

Here's what I consider essential in VIM for good file editing and better navigation:

This should be placed in ~/.exrc. You will then have auto-indentation, line numbering, etc.
