Timeshift is essentially a GUI front end for rsync. If you have a machine that uses a DE (Desktop Environment), then it is definitely a valid option.

With Apache, you can also run `apache2 -f /etc/apache2/sites-enabled/000-default.conf` and you can get a live output. It’s not as simple as `tail`, and doesnt output as verbose information, but it can be easier to remember.

`su` and `sudo` have the ability to do damage to your machine, but in the same way that a Windows `Administrator` has the ability to damage a Windows machine. They are roughly equivalent.

If anyone is interested in using GIT without a server, here is a good method for Windows: http://techs.studyhorror.com/git-without-server-i-190

As well as searching for help I’ve found that the applications also have inbuilt tools to help you, so with Apache the ‘t’ option reports on the syntax of the configuration, e.g. ‘httpd -t’ on Windows, which I imagine Linux is similar.

Another thing I’ve learnt is only to use ‘su’ / ‘sudo’ when you really need to, as the root user can destroy a disk with a single command and make the machine unuseable.

With configs another option is version control (such as Git) as they are text files, so as they change over time you can keep a ‘journal’ of the changes and easily go back to a known version that works and see the differences between versions.
