The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language.

The logical NAND is an operation on two logical values, typically the values of two propositions, that produces a value of false if both of its operands are true. In other words, it produces a value of true if at least one of its operands is false. The truth table for p NAND q (also written as p ↑ q, Dpq, or p | q) is as follows:
The true command is sometimes substituted with the very similar null command, [1] written as a single colon (:). The null command is built into the shell, and may therefore be more efficient if true is an external program (true is usually a shell built in function). We can rewrite the upper example using : instead of true:

PowerShell data sections can contain constants and expressions using a restricted subset of operators and commands. [79] PowerShell data sections are used when e.g. localized strings needs to be read from an external source while protecting against unwanted side effects.
