IFS='\n'
for i in "$(IFS='\n' printf 'abc\nxyz\n123 456\n')"; do
echo "????"
echo "$i"
done
echo "output"
echo "${args[@]}"
The following outputs:
????
abc
xyz
123 456
output
How can I get the for loop to iterate for each line? Why is the IFS='\n' command not making it behave in this manner?
The double quotes make the "command substitution" one single argument. Try without:
$ for i in $( printf 'abc\nxyz\n123 456\n'); do echo "????"; echo "$i"; done
????
abc
????
xyz
????
123 456
Plus, your IFS is set to a string containing the two chars "\" and "n". In e.g. bash, you might want to try $'\n'.
