Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

This is my personal list of functions that I wrote for converting `mov` files to `mp4`!

Command Flags

	# OBJECTIVE: Install Arch Linux with encrypted root and swap filesystems and boot from UEFI.

	# Note this encrypted installation method, while perfectly correct and highly secure, CANNOT support encrypted /boot and
	# also CANNOT be subsequently converted to support an encrypted /boot!!! A CLEAN INSTALL will be required!

	# Therefore, if you want to have an encrypted /boot or will want an encrypted /boot system at some point in the future,
	# please ONLY follow my encrypted /boot installation guide, which lives here:

	make
	./configure --prefix=/home/<yourhome>/ --with-x-toolkit=no --with-xpm=no --with-jpeg=no --with-png=no --with-gif=no --with-tiff=no
	make install
