Reading multiple files and operating on stored Arrays
I have 2 text files "${LinkP}" and "${QuestionP}. I want to read these files and store each complete line in the respective array,
IFS=$'rn' GLOBIGNORE='*' command eval "LinkA=($(cat "${LinkP}"))"
IFS=$'rn' GLOBIGNORE='*' command eval "QuestionA=($(cat "${QuestionP}"))"
Now I want to operate on these using a for loop
nLink=${#LinkA[@]} # Size of array
for ((i = 0; i < nLink; i = i + 1)); do
echo $i
Question=${QuestionA[i]}
echo "Question=${QuestionA[i]}"
done
But, the Question variable doesn't contains full line, it breaks after each space character.
How can I store each question and link (complete line in respective file) in these variable and process them inside for loop.

I'm not sure I understand the IFS requirement (are you trying to read DOS/Windows generated files?) but consider using the bashmapfilebuiltin - or its synonymreadarray
