Re: issues using printf

Hello,
I am having problems using printf in presenting my data, in
that it is all over the place.
I am using the printf command:

printf "%-10s %10s %10 %40s\n" $cont $lock $set $time_cont

You probably want "-" on all of these. The third seems to have no
format specifier; you probably want an s. Finally, be sure to quote
the arguments.

printf "%8s" $time_cont

ought to give you
"Wed Apr 1 09:35:09BST 2009 "

(with no newline).

The reason is that, if you provide extra arguments, printf cycles through
its argument string for them, and $time_cont appears to expand to multiple
words.
