bash function to "highlight" tabs and linebreaks

I don't think it's possible to give a (background) colour to the tab itself, since a tab is, IIUC, simply a command to the terminal to move to the right. Nevertheless, this "highlighting" can be helpful when working with tab-separated files. Show Sample Output

```
$ echo -e 'foo\tbar\nfie\tfum'|hl-nonprinting 
foo&#9657;    bar&#8267;

Removes single line from known_hosts file

Quickly remove the conflicting line (key) from current users known_hosts file when there is an SSH host conflict. Very nice when you get tired of writing out full commands. Ideally you would place this into your .bash_profile Usage: rhost [n] Example: rhost 33 (removes line 33 from ~/.ssh/known_hosts) Function assumes the $HOME exists, you could alternatively use "~/.ssh/known_hosts" Mac OSX likes a space for sed -i "$1" d

mhwd ? Manjaro Hardware Detection

One base component is our hardware detection. It is a C++ library and app and is designed after a dynamic structure. Any kind of hardware, no matter if usb or pci, can be configured by mhwd. There is just a simple configuration file which tells mhwd what to do. This way we also support hybrid graphics cards out of the box. However there are currently only mhwd configs for nvidia optimus setups. But this gap will be filled soon. Just play with some of those commands to get a feeling about mhwd.

Rsync remote data as root using sudo

If your user has sudo on the remote box, you can rsync data as root without needing to login as root. This is very helpful if the remote box does not allow root to login over SSH (which is a common security restriction).
