[bash] Put words from file to array

mispunt · 11-03-2004, 09:53 AM

Hi am working on a project where I should test two files. if there are some words exactly the same the script should report that.
The documents are normal text documents (or later word documents). I have a for loop to put the words into an array, so I could test two words after I have put the documents into the array. My for loop looks like this:

Code:

for line in `cat $file1 | tr ' ' '\n'`; do
                line1[$counter1]=$line
                counter1=$(($counter1+1))
done

I use this twice, so I should have two arrays. but the problem is that the array is empty after the loop. and when I echo line1[$counter] I see []

Could you tell me what I am doing wrong? I am staring to this problem to long (only one hour) but I can't find a sollution

Code:

#!/bin/bash
# file: reader
file1=reader

for word in `cat $file1 | tr ' ' '\n'`; do
#       echo $word
        word_array[$counter1]=$word
        counter1=$counter1+1
done


for index in 0 1 2 3 4 5    # Six 'words'
do
  echo ${word_array[index]}
done

--notice the curly-brackets!

thanks, it works

(although your counter didn't work for me)

On my linux server at home it worked. it was a new version of bash.
Now I am working on the server where the script should be running. It has Red Hat 6.
And the script is not working anymore

one of the much error messages:

Code:

./copy_detector.cgi: word_array[588]=color): command not found

Are arrays only for newer versions of bash? or is there still something wrong?
