I am relatively new at this, but I was wondering if it would hurt anything in Linux to add the following to the beginning of the path:

./

?? It seems logical to me, but since its not there by default, I must not know something...

Thanks in advance!

Well, after having looked at it, it sounds like a cool idea! (Hate having to type ./blabla everytime) - my Slackware however has ./ already, actually, it has '.' (without the /) - May be you just overlooked it

[EDIT]
You meant editing the PATH variable, did you?
[EDIT]

Well the reason why it's not added by default is because it can be disastrous at times. If someone places an executable called ls which does some destructive stuff and places it in the directory you are in. Then if you do a ls you will be running the bogus executable instead of getting a directory listing.

Ofcourse this does depend on the shell you are running. This won't work with bash but on ksh it will. And I'm sure there are a lot of other shells which have the same effect. So it's definetly not a wise thing to add it for the root user.
