Switches differ between commands and are documented in the manual page for each command. Some switches are common to most command though, for example '``--help``' will usually display a help text, '``-i``' will often turn on interactive prompting before taking action, while '``-f``' will turn it off.

Some common words
-----------------
This is a short explanation of some of the commonly used words in fish.
- **argument** a parameter given to a command
- **builtin** a command that is implemented in the shell. Builtins are commands that are so closely tied to the shell that it is impossible to implement them as external commands.
- **command** a program that the shell can run.
- **function** a block of commands that can be called as if they were a single command. By using functions, it is possible to string together multiple smaller commands into one more advanced command.
- **job** a running pipeline or command
- **pipeline** a set of commands stringed together so that the output of one command is the input of the next command
- **redirection** an operation that changes one of the input/output streams associated with a job
- **switch** a special flag sent as an argument to a command that will alter the behavior of the command. A switch almost always begins with one or two hyphens.

The other conditionals use the `exit status <#variables-status>`_ of a command to decide if a command or a block of commands should be executed. See their documentation for more information.
