Just a heads up on something I hadn't noticed: Bash (and dash) treat
octal literals in printf precision inconsistently (using glibc -- not
sure if it's a bug or GNUism on that end or the shell):
$ bash -c 'printf "<%.010d> <%.*d>\n" 1 010 1'
<0000000001> <00000001>
Zsh is also inconsistent, but in the reverse direction:
$ zsh -c 'printf "<%.010d> <%.*d>\n" 1 010 1'
<00000001> <0000000001>
ksh93 of course follows its usual pattern of ignoring octal literals
entirely:
$ ksh -c 'printf "<%.010d> <%.*d>\n" 1 010 1'
<0000000001> <0000000001>
(...and if everybody else follows suit, they won't be missed. Worked out
fine for ECMAScript5 strict.)
