Use fold utility with width=1:

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

e
x
a
m
p
l
e
1

Another option is grep -o:

echo 'Example example1' | grep -o .
E
x
a
m
p
l
e

e
x
a
m
p
l
e
1

This is a perfect recipe for `fold`! – devnull Dec 03 '13 at 14:05

Not really a bash solution, though, since you're calling external utilities. – Petr Skocik Dec 03 '13 at 15:36

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
