Hi there,
Normally, "${var:?'message'}" display error if null or unset if
'message' is omitted. But if it is not, a particular message can be
included, in any case, shows (e.g):
myscript: line 2: var: parameter null or not set
My question is, there is a way to print only the message? (removing
myscript: line number: var:)
