This article explains how to correctly handle filenames in Bourne shells (the primary shell of Unix/Linux/POSIX systems), based on the issues discussed in ‘Fixing Unix/Linux/Filenames’. Many programs fail to work properly on filenames that include spaces, begin with dash (-), include newlines, and so on, because developers don’t know how to do it properly. Many texts, even good ones, get this wrong.

I often write documents, such as exams and lecture notes, that contain both Latin and Arabic script, often on the same line of text. This can be challenging due to the complications of mixing of LTR (left-to-right) and RTL (right-to-left) scripts. This seems like an easy problem to solve for software developers, and it is, only not in software with graphical WYSIWYG interfaces, such as Word or OpenOffice. (I’m sure everyone who has tried writing mixed direction text in such software share my frustration with them, and I will therefore refrain from rants.) Since my shift to exclusively producing and editing text in plain text formats (.txt, .mkd, .tex, etc.) with the editor Vim, writing texts with mixed directionality has become a lot easier. This post is an attempt to explain how.
