Hack #1: Tool Script

This is the script I have created that will check if all the prerequisites from the Tools and Equipment Overview have been fullfilled for a MacOS System.

%%bash
echo "Starting the Tools and Equipment Overview Confirmation Script..."

echo "Checking Homebrew..."
if which brew | grep -q "not found"; then
    echo "Homebrew not installed! Install Homebrew to complete the script!"
    exit 1
else
    echo "Homebrew installed!"
fi

echo "Checking GitHub..."
if ls /usr/bin | grep -q git; then
    echo "Git installed on Host"
else
    echo "Git not installed on Host!"
fi

echo "Checking VSCode..."
if ls /Applications/ | grep -q "Visual Studio Code"; then
    echo "Visual Studio Code installed on Host"
else
    echo Visual Studio Code not installed on Host!
fi

echo "Checking Jupyter Notebook..."
if brew list | grep -q "jupyterlab"; then
    echo "Jupyter Notebook installed on Host"
else
    echo "Jupyter Notebook not installed on Host!"
fi

echo "Checking Slack..."
if ls /Applications/ | grep -q "Slack"; then
    echo "Slack installed on Host"
else
    echo Slack not installed on Host!
fi

echo "Checking Docker..."
if ls /Applications/ | grep -q "Docker"; then
    echo "Docker installed on Host"
else
    echo Docker not installed on Host!
fi

echo "Checks complete!"
exit 0

Git installed on Host
Checking VSCode...

Checking Jupyter Notebook...
Jupyter Notebook not installed on Host!

Linux Commands

Here is my blog of Common Linux Commands

How do we confirm packages

If we are doing a package manager install, ususally you can write list commands for all types of systems. For example, on Ubuntu, you can write

%%bash
dpkg -l | less

bash: line 1: dpkg: command not found

And on Mac with Homebrew, you can write

%%bash
brew list | less

autoconf
automake
bison
black
brotli
c-ares
ca-certificates
cairo
cffi
chruby
fontconfig
freetype
gdbm
gettext
giflib
git
glib
gradle
graphite2
harfbuzz
icu4c
ipython
jpeg-turbo
libffi
libidn2
libnghttp2
libpng
libsodium
libtiff
libunistring
libuv
libx11
libxau
libxcb
libxdmcp
libxext
libxrender
libyaml
little-cms2
lz4
lzo
m4
md5sha1sum
mpdecimal
mypy
node
openjdk
openssl@1.1
openssl@3
pandoc
pcre2
pixman
pkg-config
pycodestyle
pycparser
pydocstyle
pygments
python-certifi
python-lsp-server
python@3.11
pyyaml
readline
ruby-install
six
sqlite
wget
xorgproto
xz
zeromq
zstd

Usually, with most packages, you can do the following to get the version.

[package name/command] -v
[package name/command] --version

If you want more information, a lot of packages have the following features.

[package name/command] -h # Package manual
[package name/command] --help # Package manual
man [command] # Linux manual for the command of the package

If you are installing packages from an outside source, make sure the package comes from the official company website and scan the installer with an antivirus.

If you are concerned that the download is corrupted while it was transferred, then you can get a checksum from the website and calculate the checksum on your computer. For example, if you have an md5 checksum of a .gif file, you can run the following command:

rachitjaiswal@Rachits-MBP# md5sum Desktop/yomp.gif
bc75b5ce8a75c1f4c7ed1e51b113353b  Desktop/yomp.gif
rachitjaiswal@Rachits-MBP#

This can be verified if you download the gif and check for yourself. Even if the .gif is on a completely different architecture, the file will still have the same md5 sum, and if it is tampered with or malformed, the sum will change. Using something like this on an .exe or a .pkg file ensures that the package is valid and that it comes from the source, without being tampered or malformed.

Updating a Repository with the command line

To update a git repository with your command line, you must follow the steps below.

# 1. Open a terminal and navigate to the directory of your github repository on your localhost
# 2. Use the following command to add a repository.

git add .

# 3. To verify the status of the repository, run the following command
