enhancement of echo

well, i don't know if it is a drawback, per se, but there is a built-in function in the shell (I use bash) call echo. This sometimes confuses me when I think I'm calling the echo utility from gnu coreutils.

I personally prefer to use printf, b/c I like the greater flexibility it has in string formatting, etc.

make some nice columns in output:

printf "%-20s%s\\n" meh blah
printf "%-20s%s\\n" foo bar

round up to a whole number:

printf '%0.f\\n' 1.5

convert hex to decimal:

printf '%d\\n' 0x100000000
