practice test # 26

[janet tuma]

26. What command adds /home/roddyduk/bin to your path?

From what I gather this is a .bash_profile issue (lesson 12 slide 69) but I need more info as I don't see any examples and can't remember doing this

Any help out there?

Sorry I do not know... I was hoping help would arrive for both of us...
its tomorrow, hopefully you will have your answer by then
as typical for me, I am only NOW 1:40 Tuesday working on the practice test... its so hard.... does this get easier????
the first question has me ??? I'll remember I know we have done this on several occasions....

Think about this as just another question on variables. You can set a variable to a text string or a variable or both:
[code][rsimms@opus ~]$ s1="First sentence"
[rsimms@opus ~]$ s2="Second sentence"
[rsimms@opus ~]$ paragraph="$s1. $s2."
[rsimms@opus ~]$ echo $paragraph
First sentence. Second sentence.
[/code]

The variable on the right side of the = sign does not have to be a different variable:
[code][rsimms@opus ~]$ cities=AnnArbor:Remus:Ypsilanti
[rsimms@opus ~]$ echo $cities
AnnArbor:Remus:Ypsilanti
[rsimms@opus ~]$ cities=$cities:Kalamazoo:Dexter
[rsimms@opus ~]$ echo $cities
AnnArbor:Remus:Ypsilanti:Kalamazoo:Dexter
[/code]
See if you can now do to the PATH variable what I just did to the cities variable.

ok - I'll give this a try! Thanks Rich -

By the way Patrick, look at the power points and you'll find your answers. Start at lesson 10 and you'll move right along. Rich keeps these well organized and the class work is close enough to the pre-test to find what you need!
