\section begin begin - Start a new block of code \subsection begin-synopsis Synopsis begin; [COMMAND;...] end \subsection begin-description Description The \c begin builtin is used to create a new block of code. The block is unconditionally executed. Begin is equivalent to if true. The begin command is used to group any number of commands into a block. The reason for this is usually either to introduce a new variable scope or to redirect the input to output of this set of commands as a group. \subsection begin-example Example The following code sets a number of variables inside of a block scope. Since the variables are set inside the block and have local scope, they will be automatically deleted when the block ends.
begin
	set -x PIRATE Yarrr
	...
end
# This will not output anything, since PIRATE went out of scope at the end of
# the block and was killed
echo $PIRATE
