Not as bad as the OP's use of HTML. I've looked at that post in its text version, the raw HTML, as rendered by lynx, and in firefox, and it looks as though the PATH ends with a colon. So I'll just point out that if you want the current directory in your PATH, then make it explicit with a period, as in: … … …games:/usr/games:/snap/bin:libtool:. and if you don't, then remove the final colon, as in: … … …games:/usr/games:/snap/bin:libtool If ever you want to run, say, foo in your current directory, then just type: $ ./foo But in view of the newish semantics for su, I'd strongly advise against having PATH include the directory that you just happened be in at the moment. Cheers, David.
