One common thing you have to do when doing Sysops, is uploading or downloading files. Most times you've got a SFTP connection to do so, but often times that's not possible and you only have a SSH connection available. Every time I have to do this, I again search how to do it : ) Time to put it in a short instruction:

scp /path/to/local-file ssh-username@your-host:/path/to/destination

So for example:

scp project/.htaccess liplex@edisonn:/var/www/html/project/.htaccess

The your-host part is whatever name you put into your ~/.ssh/config file. In my example it would be:

Host edisonn
    HostName edisonn.de
    User liplex
