Patterns and string processing in shell scripts

"Shell programming is heavily dependent on string processing. The term string is used generically to refer to any sequence of characters; typical examples of strings might be a line of input or a single argument to a command. Users enter responses to prompts, file names are generated, and commands produce output. Recurring throughout this is the need to determine whether a given string conforms to a given pattern; this process is called pattern matching. The shell has a fair amount of built-in pattern matching functionality."

Characteristics of "Gentle Action"

"Theoretical physicist F David Peat has written a wonderful book titled "Gentle Action."

Peat suggests that gentle action is a "kind of minimal but highly intelligent activity that arises out of the very nature of the system under investigation" (Gentle Action, p. 137). He proposes this concept as an alternative to Newtonian or mechanistic metaphors for action."
