quick question about '%s' expansion

quick question about '%s' expansion

[Simon Hausmann]

Hi,

I have a question regarding the expansion of '%s' for
commands. Issuing

	date +%s

results in the following output

	" date "+" date "+"999985277

using zsh 4.0.2 . However it works correctly (just printing the
amount of seconds) using an older zsh (3.x) . 
Is this a bug in 4.0.2?


Thanks,
Simon

{pts/2}% date +%s
999985938
{pts/2}% echo $ZSH_VERSION
4.0.2

Check with zsh -f. Is it possible that date is aliased/defined as function?

Ah, yes, with -f it works. Silly me, I had a preexec which looked like

	preexec () {print -Pn "\e]0;%n@%m: $*\a"}

and apparently the %s got caught by the prompt expansion, causing output
beyond the xterm escape sequence. I splitted it up in two print's 
(one with -P and one without) and now it works :)

The definition of preexec changed just before the 4.0 release.  Re-read
the manual entry for it.  You almost certainly want to use $1 or $2, not
$*, in your xterm title.

Whoops, $1 looks much better, indeed. Thanks for your help!
