Under FPC/Linux, does anybody know how to get the directory the program
binary file resides in?

For DOS/Win/OS/2 programs, I use the function;

Function Exedir: String;
var
  S: string;
begin
  S := ParamStr(0);
  if Pos('\', S) > 0 then
    while S[length(S)]  '\' do Dec(S[0])
  else S := '';
  Exedir := S;
end;

(For Linux, of course, I reversed the slashes.) This procedure doesn't
seem to work for me, and for all I know, I've got files created in junk
paths :<
