Random word

[keyvanrahmadi]

I am trying to undcerstand how to randomise an out of the file. My file is currently consisnt of 10 words as follow:

word1, word2, word3, word4, etc....

cat words | cut -d" " -f1
 

this will give me the first word in the first field. since there is multiple words, how do you randomise the selection of the words?

just an example

word=$(awk 'BEGIN{FS=",";srand()}
{
      for (i=1;i<=NF;i++) {
        word[i]=$i
      }   
      print word[int(rand() * NF )]
}
' "file")
echo $word

If you want to do that only with bash, you may use arrays and random values. Look for $RANDOM.
