split a string into array in bash return wrong size
 
Hi,

I'm trying to split a string, to later iterate using a for loop like
Code:
for (( i=0; i<5; i++))
But, my script returns an array with the size 1.

Here's the script:
Code:
aver=$(grep "avg" A.txt | awk '{ print $2 }');
a=$(echo $aver | tr " " "\n");

echo ${#a[@]};

for (( i=0; i<${#a[@]}; i++))
do
    echo -e $i"\t"${a[$i]}";
done
What's wrong with the script?

Can you make the file A.txt or a file with the same syntax available to us?

It is hard to find out where things goes wrong without knowing how the file looks like.
If you link to a copy of the actual file remember to remove any sensitive information.

Same problem as here. You missed the parentheses for array assignment:
Code:
a=( $(echo $aver | tr " " "\n") )
