Error Getting Files from list and jumbles them
Hi,

I was wondering if you could help as I'm sure its possible. I can remember something was possible using sed/awk a while back.

I have a list in a file such as sample_list.txt which contains the following:

Code:
example1, answer1
example2, answer2
example3, answer3
example4, answer4
example5, answer5
example6, answer6
example7, answer7
example8, answer8
example9, answer9
example10, answer10
e.t.c

What I want to do is to create a script and when it runs:
  1. It lists either the first or second field and places it on the left hand side
  2. It then places its corresponding example/answer on the opposite side
  3. It repeats this for 10 of the words and then shuffles the words

example:

Code:
example8	answer1
example10	answer6
example1	answer8
answer3	example5
example7	answer9
example9	answer7
answer2	answer9
example6	example3
example4	example2
answer5	answer4

Hope this helps.

Thanks

I do not understand the practical use for something that takes a random number of examples (let us call this random number of examples example_count) where example_count is an integer such that 1 <= example_count <= 20 and then takes 20 - example_count answers to produce 10 lines of output some of which have two examples, some of which have two answers, some of which have an example followed by an answer, and the rest have an answer followed by an example.

I could imagine needing to extract 10 examples and the 10 answers corresponding to those examples and creating 10 lines with the examples on the left and the answers on the right (but with the answers in random order) or creating 10 lines with the answers on the left and the examples on the right (but with the examples in random order), but neither of these match the output you say you want.

Is this a homework assignment? Homework and coursework questions can only be posted in the Homework & Coursework forum with a completely filled out homework template that is available in the special homework rules.

If this is homework, please review the guidelines for posting homework and repost.

If it is not homework, please explain how this project will be used.

Hi,

Thank you for getting back to me.

I can see why you think it's homework :-)

I would like you to know that it is not part of homework but is a process carried out by the local school teachers on a daily basis. To make life easier for them I suggested that it could be done using sone form of shell script and that is where I thought you guys came in.

Hopefully this clears and misunderstanding on my part.

Thanjs

Good you pointed that out.

Still I'm missing the point. What be
- "its corresponding example/answer"?
- "shuffles the words" and its effect?
I can't even infer that from the samples given. Why does example8 correspond to answer1?

okay.

On a weekly basis each class is given synonyms to do.
These are generated from a synonyms file which contains the following

Code:
abandon, leave
abbreviate, shorten
abode, dwelling
abrupt, sudden
...
..
.

so the left hand side you would have the words
Code:
abandon
abbreviate
abode
abrupt

on the right hand side you will have
Code:
sudden
dwelling
leave
shorten

The order does not matter.

So as pupils get the sheet they have to draw lines to match the synonyms.
Hope that helps.

Unfortunately, you didn't really answer my questions. Based on some assumptions, I came up with

Code:
awk '
        {EX[NR]  = $1
         EX[-NR] = $2
        }
END     {for (i=1; i<=NR; i++)  {IX = 0
                                 IY = 0
                                 do     IX = int(rand()*20)-10
                                 while  (!(IX in EX))

                                 SGN = (IX < 0)?1:-1

                                 do     IY = SGN*(int(rand()*10)+1)
                                 while  (!(IY in EX) || IY == SGN*IX)

                                 printf "%-15s %-15s\n", EX[IX], EX[IY]
                                 delete EX[IX]
                                 delete EX[IY]
                                }
        }
' FS=, file
example7        answer10       
answer2         example6       
example2        answer5        
answer3         example10      
example9        answer1        
answer6         example4       
example8        answer9        
example5        answer8        
example3        answer4        
answer7         example1

Does it come close to what you imagined?

This one would make you independent of the input row count; use it on files of arbitrary length...
Code:
awk '
        {EX[NR]  = $1
         EX[-NR] = $2
        }
END     {for (i=1; i<=NR; i++)  {IX = 0
                                 IY = 0
                                 do     IX = int(rand()*2*NR) - NR
                                 while  (!(IX in EX))

                                 SGN = (IX < 0)?1:-1

                                 do     IY = SGN*(int(rand()*NR)+1)
                                 while  (!(IY in EX) || IY == SGN*IX)

                                 printf "%15s      %-15s\n", EX[IX], EX[IY]
                                 delete EX[IX]
                                 delete EX[IY]
                                }
        }
' FS=, file
