Trying to find Latex template

[maksimdrachov]

Hi,

I'm trying to find a template that's as close as possible to the bashguide pdf: https://folk.ntnu.no/geirha/bashguide.pdf

What I'm particularly interested in is:

• the way code blocks are greyed out
• source links at bottom of the page
• overall style/feel/lettering type of the document

Can anyone point me in the right direction?
