Path

Can anyone help me with this i'm not sure what the answers are.

Q1 If "." is not in the PATH, what does it mean?
1. The current directory is not readable.
2. The current directory is readable but not executable.
3. Executable programs cannot be scattered everywhere - they must be in a small number of predefined directories.
4. Programs may be executed from anywhere.

Q2 Why is it a security risk to put "." in the PATH?
1. Other users' programs might use the same names as system programs.
2. You could end up running system programs instead of your own programs.
3. You could end up running your own programs instead of system programs.
4. Other users can then read your current directory.

thanks

Q3. Did you read the forum rules?

1.No homework or assignements post in this forum.
2.Do check Forum Rules
3.Search the Forum Search Funtion

Do understand the forum rules, homework was meant for you to do it yourself rather then post in this forum.

Its not homework or an assignment. The reason I asked the question was because i don't know the answer and I was hoping somebody might be able to help, or at least point me the right direction.

How did it come to pass that you asked multiple choice questions?

I found it on an irish OS paper and didn't know the answer. Should it matter or do you want my life story aswell?? Obviously I have searched for material that would help but couldn't find any relevant information, hence why I asked it on the boards (Isn't that why there are boards? Ask ppl for help/info.?)

Cheers

The reason that it matters is that multiple choice questions look very much like homework. And homework is against the rules of this board. But I will take your word that this is not homework.

The answer to the second question is 1.

Hmmm...I dont't like any of the choices for question one. A dot in the PATH means that the current directory will be searched when you type a command. And I have never seen that done. A null entry in PATH means the same thing and most people will do that. A few examples will help...

PATH=/usr/bin:/usr/local/bin
will search /usr/bin and then /usr/local/bin.

PATH=/usr/bin:/usr/local/bin:.
now after the first two, we will search the current directory.

PATH=/usr/bin:/usr/local/bin:
this does the same thing as above.

If you searched why didn't you find it? All I did was search for ' unix security path' and found what you needed to understand all of this.

I agree it sounds more like homework, Perderabo.
