Also as a function you can just supply the value as a parameter instead of
hard coding the use of $var. you could even default to a predefined named
variable if no parameter is specified, e.g.

tst() {
    fold -sw 80 <<<"${1:-$var}" | sed '...'
}

Which will operate on whatever you pass to it but if you don't pass
anything will use the value of $var.
