Hammer & Screwdriver To show the ASCII value of "A"

There are probably simpler ways, but I use that 'od...' command often when trying to diagnose data issues. It helps to find strange characters in text.
The first example is the decimal represenation of "A" and the second is the octal representation.

Code:
> echo "A" | od -An -t dC | awk '{print $1}'
65
> echo "A" | od -An -t oC | awk '{print $1}'
