You won’t be able to directly use your PuTTY‘s key in Linux‘s OpenSSH because the keys are of different format. You’ll need to first convert PuTTY‘s key to OpenSSH‘s key format by following these steps;

1. Download PuTTY Key Generator (puttygen.exe) from the following URL

   https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

2. Launch the program and click on the Load button and select your PuTTY‘s key file, which normally ends with .ppk extension.
   
   
3. Enter the key’s passphrase if prompted.
   
4. Details of the imported key will be displayed.
   
5. Go to Conversions → Export OpenSSH key from the menu.
   
6. Save your converted key to a new file and location.
   

Beginning version 7 of vim, it has this nice auto completion feature. It is by default however limited to words that has already been in the current workspace. To use it, simply press [ctrl] +n or [ctrl] + p key while in edit mode. For example:

We can however *teach* vim to autocomplete a whole bunch of other stuffs as well, by using something so called Dictionaries. With this idea we can have auto completion for Python, Ruby, PHP, Bash, and any other programming languages code.

For an example, let’s try to install Python dictionary, by downloading it from here:

http://www.vim.org/scripts/script.php?script_id=850

The next thing to do is to extract the downloaded file to the appropriate folder:

shakir@herugrim ~ $ mkdir ~/.vim
shakir@herugrim ~ $ tar xf pydiction-0.5.tar.gz -C ~/.vim

and add this lines to your ~/.vimrc (be sure to replace “/home/shakir” to your own home directory)

if has("autocmd")
    autocmd FileType python set complete+=k/home/shakir/.vim/pydiction-0.5/pydiction isk+=.,(
endif " has("autocmd"

and let’s see the result:

There are many other scripts available at Vim’s script page worth trying as well.
