So I have this list of 40 questions I want in a unique order 351 times

The list of questions is in a text file but I am willing to copy and paste them into whatever format is needed.

I need 351 unique sets of the same questions witch each set in a different order. What can I do on ubtunu to hit my needs?

Searching the web: http://en.wikipedia.org/wiki/Permutations

You want a reduced set of permutations (40 questions taken 40 at a time, order is important AND no repetition of questions). The following link is a calculator and list creator: http://www.mathsisfun.com/combinator...alculator.html with some explanation: http://www.mathsisfun.com/combinator...mutations.html

In linux, two commands are helpful apropos and apt-cache search:

tgalati4@Mint14-Extensa ~ $ apropos permutation
shuf (1) - generate random permutations
tgalati4@Mint14-Extensa ~ $ apt-cache search permutation
libbtf1.1.0 - permutation to block triangular form library for sparse matrices
libsuitesparse-dbg - libraries for sparse matrices computations (debugging symbols)
libsuitesparse-dev - libraries for sparse matrices computations (development files)
libsuitesparse-metis-3.1.0 - collection of libraries for computations for sparse matrices
libsuitesparse-metis-dbg - collection of libraries for computations for sparse matrices
libsuitesparse-metis-dev - collection of libraries for computations for sparse matrices
libalgorithm-permute-perl - module to perform permutations with object oriented interface

libghc-hcard-prof - library for implementing a Deck of Cards; profiling libraries
libitsol-dev - ITerative SOLvers - devel
libitsol1 - ITerative SOLvers - runtime
libmath-combinatorics-perl - module for performing combinations and permutations on lists
libstring-glob-permute-perl - Expand {foo,bar,baz}[2-4] style string globs
libxml-semanticdiff-perl - Perl extension for comparing XML documents
python-pytools - big bag of things supplementing Python standard library
python3-pytools - big bag of things supplementing Python 3 standard library
r-cran-gregmisc - GNU R package with miscellaneous functions by Greg Warnes et al
r-cran-permute - R functions for generating restricted permutations of data
unsort - reorders lines in a file in semirandom ways

apropos will search your system for any commands that have a keyword, in this case permutation. apt-cache search will search the repositories for any packages that might perform permutations.

You can write a script to take your list of 40 lines and jumble it 351 times to create your new lists.

From apropos, there is a command call shuf (presumably from shuffle) that gets you closer:

Open a terminal:

man shuf

You can also install unsort and see what it offers.

There are probably 10 ways to do this, but you want to find the most elegant way.

Create a text file with your 40 questions and start playing with it:

tgalati4@Mint14-Extensa ~ $ cat shuffle_test.txt
This is line number 1.
This is line number 2.
This is line number 3.
This is line number 4.
This is line number 5.
This is line number 6.
This is line number 7.
This is line number 8.
This is line number 9.
This is line number 10.
tgalati4@Mint14-Extensa ~ $ shuf shuffle_test.txt
This is line number 5.
This is line number 9.
This is line number 1.
This is line number 7.
This is line number 4.
This is line number 2.
This is line number 3.
This is line number 6.
This is line number 10.
This is line number 8.

Now write a script to check for duplicates and save to unique file names.

Do you know something about statistic and programming?

Is this a class assignment?

Is it ? bostoncab2 please answer the question, thanks.

Here you go, Mike.
Run this:

#!/bin/bash
set -e

echo -e "\nStep 1: Get a deck of playing cards." \
  "\nStep 2: Remove the jokers and the face cards." \
  "\nStep 3: Use gedit in Ubuntu to create a text file where you manually map each of the remaining forty cards to a unique question."
for i in {4..1056..3}; do
  echo "Step $i: Manually shuffle the cards."
  echo -e "Step $(( i + 1 )): Create a new text file using gedit in which you arrange the questions according to the order of your shuffled cards" \
  "\n           and the mapping you made in Step 3."
  echo "Step $(( i + 2 )): Print the file on a piece of paper."
done
echo -e "Step 1057: Stack all your printed papers and bind the stack with a couple of rubber bands." \
  "\nStep 1058: Turn the stack in to your teacher." \
  "\nStep 1059: Don't worry about any duplicates in your stack." \
  "\n           There's hardly any chance that your teacher is going to check them.\n"

exit 0

Don't work too hard, Mike.

for f in {1..351}; do shuf --random-source=<(echo $f) input.txt > output${f}.txt; done

The above assumes that you want each permutation in a different file; you will end up with 351 output files. Please note that I haven't tested this extensively.

...The above assumes that you want each permutation in a different file; you will end up with 351 output files...

It also assumes it isn't homework, which is an assumption that is this close --><-- to impossible for me.
Perhaps I'm getting increasingly crusty with age, or I'm suffering from chronic female supervision deficiency syndrome, or both.

Since answers are still being given despite the fact that the OP has not yet answered the question as to whether or not this is homework, I've closed the thread, at least for the time being.
