Ladies and Gentlemen,
I thought I understood how arrays work in bash, but I have been proven
wrong. I am reading lines from a file and placing them in an array.
However, when I am finished, the array has a length of 0.
Following is the code I am using.
#!/usr/local/bin/bash
COUNTER=0
cat ./test_file.txt | while read LINE
do
echo ${LINE}
FOO[${COUNTER}]=${LINE}
COUNTER=`expr ${COUNTER} + 1`
done
echo ${#FOO[@]}
echo ${#FOO[*]}
And, here is the output.
test_file
file_size
0
0
Thanks in advance for any help you can offer.
Jay
