What is the difference between single dash and double dash?
Basically, a single dash means that the following flags are single-character only, and generally means that more than one flag can be passed. See all other command line tools: ls -la grep -inr “asd” . The double dash connotes a single positional flag/argument to a command line tool.
What do double dashes mean?
Double dashes are used instead of commas (or parentheses) to interrupt a sentence. It is often said that we use dashes to signal that something crucial is being added to a sentence and use parentheses to signal that the interruption is relatively unimportant (e.g., to give dates or citations or examples).
Do dashes have to come in pairs?
There are two slightly different conventions for using a dash. The dash has only one use: a pair of dashes separates a strong interruption from the rest of the sentence. (A strong interruption is one which violently disrupts the flow of the sentence.)
