No, it's the opposite that is potentially dangerous. For instance, you install some executable foo in your ~/bin, so that you can run just "foo". Then, imagine that after some system upgrade or package installation, a new executable "foo" gets installed somewhere in the system path. So, when you run "foo", it will no longer be your executable, but the system one, and if this executable is destructive, you may lose data... It is "." that must never be put in front of the path. Putting it at the end might be OK, but this is not even recommended, due to the above issue and also because you may run a wrong executable by mistake. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
