Count how many characters are in the program's source
Bash, 10



Pretty boring, but:


Prints the code size in bytes, and nothing else.
Filename may contain spaces.


Make sure that the file doesn't have a new line at the end! If it does, it will output 11.

wc -c&lt;"$0"


If the file doesn't have spaces in its name, you can get 8 characters:

wc -c&lt;$0
