Have defined an array local to a function
isufx+=( -name "*$fltyp" -o )
When I call the function again, the previous values in array isufx are not being cleared and the array unset. Instead the values of tho second function call are being appended to those mad in the first call.
How can the array isufx be refreshed when calling it again?
You could create your function in a subshell instead of using the traditional curly brackets.
my_func () (
local isufx+=( -name "*$fltyp" -o )
do-the-things
)
isufx to another array which was not defined as local. Thusly, the problem emerged.
local... E.g. foo() { local foo+=bar; echo $foo; } prints bar just once, regardless of how many times it was called before. (Also, I have this awkward feeling that doing the assignment right in the local was problematic in some cases, but I can't remember why.)
isufxdeclared aslocalthere? Initialized by a regular assignment? By default, shell variables are global, and if all you do to one, is to append more elements, well, then it indeed never clears.
