# The VirtualBox documentation[1] for how to install guest additions 
# for Linux on a virtual host is somewhat messy. So here is what 
# I did to make it work.

# Install the packages required
yum update
yum install gcc kernel-devel make

reboot

# Set name of the theme to load --- if set to "random", it will

Recently found some clowny gist was the top result for 'google takeout multiple tgz', where it was using two bash scripts to extract all the tgz files and then merge them together. Don't do that. Use brace expansion, cat the TGZs, and extract:

$ cat takeout-20201023T123551Z-{001..011}.tgz | tar xzivf -

You don't even need to use brace expansion. Globbing will order the files numerically:

$ cat takeout-20201023T123551Z-*.tgz | tar xzivf -

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git
