$unshift(<variable name> <word list>)
Whereas the “shift” operation removes the first word from a word list (or variable), the “unshift” operation prepends words to the beginning of a word list in a variable and assigns the result back to the variable.
The new value of $<variable name> after the unshift.
assign -foo $unshift(foo blah) assigns "blah" to $foo and returns "blah" $unshift(foo booya) prepends "booya " to $foo and returns "booya blah"
