could you give me maybe good urls about such to learn ( maybe not too long
ones .. ) ?

i can paste the two missing functions
or even paste the archive where they come from ( this same project )

it may also be non bash errors cause more newer sw used than usual.. no

to paste minimally additions, here are the two funcs
they are for code shortening there, not always to retype etc..

mkPATH is a function
mkPATH ()
    declare pre onlyargs IFS=: T=;
    declare -A t=();
    end='PATH=$T' per "${pre[@]}" ${onlyargs-$PATH} "$@"
'T=${T:+$T}${t[$per]-${t[1]+:}$per} t[$per]= t[1]='

per is a function
per ()
    declare per pre stu beg end;
    eval -- "$pre";
    for per in "${@:1:$#-1}";
        eval -- "$beg
    eval -- "$stu"
