General Linux Commands

• This is indeed the general form for all Linux commands, although there are (as always) some exceptions:

command [flags & keywords] [filename list]

• That is, the command name (which might include a path) is followed by an optional (usually) set of command modifiers (usually) in any order or combination, and ends with an optional (often) list of filenames (or filespecs)

• In a pipe chain (cmd1 files | cmd2 | cmd3) of filters, the filename list is commonly found only on the first command.
