Use fold utility with width=1:

echo 'Example example1' | fold -w1
E
x
a
m
p
l
e

e

Another option is grep -o:

Answer 2

Using standard unix tools, you can do, for example:

echo "Example example1" | sed 's/\(.\)/\1\n/g'

Using pure bash:

echo "Example example1" | while read -r -n 1 c ; do echo "$c"; done
