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.
That is really clever. Come to think of it, there could be cases where
it could have that sort of utility.
