Working with Octopress I tend to do a lot of editing in an offline text editor ( Sublime ) and then copy / pasta the content in my “_post/*.markdown” files.
For a while I ended up deleting the file and recreating it using “cat” but this was a bit cumbersome.
Decided to open up the old Google and dig up how you can do this quicker.
Solution #1
1. Type gg
to go back to the start of the file
2. Type dG
to delete all lines
Solution #2 ( bit more elegant )
1. Type %d
to delete all the things
Hope this helps someone out.
