Andrew, what is the difference between arrays and lists? 

29:39 - Girish 
You used lists in your for loops before. Are those same as arrays? 

30:21 - Girish 
OK Thanks. 

42:10 - Benjamin 3 
When I do a for loop using integers, I really like using the `seq x y` command. 

42:23 - Fiona R #2 
The ` ` can be used to assign a bash variable to the result of a bunch of Unix commands 

42:52 - Fiona R #2 
e.g. myvar = `tail - 1 myfile.txt` 

43:10 - ChristopherWalker 
Isn't $(bash command) better than ` ` as it nests. 

43:15 - Mike M 
you did 3 apruns concurrently; how do the core allocations work out?  Does aprun manage that for you 

43:32 - Fiona R #2 
I didn't know about the $( ) one! 

44:00 - Benjamin 3 
<<EOF is a useful thing to know for incorporating eg gnuplot into bash scripts 

44:06 - David 
In the array example, if If I did array[6]=pink 	 
 would the array length be 7 (the array is 7 long) or 6 (it has 6 defiined entries). Is array[5] now undefined? 

44:44 - David 
Answer to aprun question: aprun acts like a mini-scheduler and schedules your jobs within the node allocation 

45:19 - David 
It will queue them up: they may not even run in order if a small job is later in the list 

46:35 - Fiona R #2 
I quite often use bash to auto-generate .pbs files via by cat-ing in my script between EOF's 

47:07 - Fiona R #2 
You need to the variables when doing that 

47:55 - Fiona R #2 
Thanks Andy, very useful :) 

47:56 - David 
Yes - I learned loads I didn't know. Thanks! 

47:57 - Benjamin 3 
maybe something about making aliases would be good in this tutorial 

47:58 - QM22 
no, thanks! Just to thank you for your time 

47:59 - QM22 
very useful indeed. 

48:00 - Mike M
