Re: [Linuxcommand-discuss] shell printf function

[William S. <bs...@pa...>]

In bash, the correct format would be:

printf "# %-65s #\n" "$current_uptime"

Don't use the parens.  Also, you need to quote the argument since it
contains embedded spaces.  Lastly, you should include the "\n" in the
format string since there is no carriage return if you don't explicitly
specify it.
