Answering specific questions about using command line applications on Unix-like operating systems is usually not very hard — a few Google terms more often than not pulls up a topical Stack Overflow question. If you want to find what a Bash option does, or how to delete a word in Vim, you won’t struggle.
However, I’ve found it can be harder to find good general sources of
information on the web about these applications. If you want to learn more
about a particular editor, shell, or debugger, it’s tougher to find a single
source of organised, high-quality, and up-to-date information. As helpful as
man pages are for experienced users, their terseness can be a major deterrent
for newbies. I’d like to try and help fix this, hence this page (and the
Arabesque blog in general).
Links are grouped by application, sorted with my rough opinion of how useful I have found them as a source of information about a particular command line application. Each link is accompanied with a short summary description. Many of the links are blogs; I will add single blog posts if they’re exceptionally helpful, but a link to a whole blog or at least a post category would be preferred.
