Print output with printf not echo

Print output by using the command printf instead of the command echo. This is because of security, stability, and consistency across systems.

Yes:

printf "%s\n" "foo"

No:

echo "foo"

The command printf does everything that the command echo does, and more.

Some reasons:

• The command echo isn't consistent across operating systems.

• The command echo output options can confused with command line flags.
