\subsection switch-description Description
The \c switch statement is used to perform one of several blocks of
commands depending on whether a specified value equals one of several
wildcarded values. The \c case statement is used together with the \c
switch statement in order to determine which block should be
performed.
\c switch performs one of several blocks of commands, depending on whether
a specified value equals one of several wildcarded values. \c case is used
together with the \c switch statement in order to determine which block should
be executed.
Each \c case command is given one or more parameter. The first \c case
Each \c case command is given one or more parameters. The first \c case
command with a parameter that matches the string specified in the
switch command will be evaluated. \c case parameters may contain
wildcards. These need to be escaped or quoted in order to avoid
regular wildcard expansion using filenames.
Note that fish does not fall through on case statements. Though the
syntax may look a bit like C switch statements, it behaves more like
the case statements of traditional shells.
Note that fish does not fall through on case statements. Only the
first matching case is executed.
Also note that command substitutions in a case statement will be
evaluated even if it's body is not taken. This may seem
counterintuitive at first, but it is unavoidable, since it would be
impossible to know if a case command will evaluate to true before all
forms of parameter expansion have been performed for the case command.
Note that command substitutions in a case statement will be
evaluated even if its body is not taken. All substitutions, including
command substitutions, must be performed before the value can be compared
against the parameter.
