Hi,
Could anyone tell me a way to make the following work from a z-shell:
rm -rf *.o (this dosn't work)
What I want is to remove all .o files recursive , but the "-r switch" in
the above isn't a correct way to do it.

rm -f **/*.o
or with *** instead of ** to follow the links.
See man zshexpn...

rm -f **/*.o
might work a little better

*.o is interpreted by zsh as: expand all the filnames in the current
directory matching '*.o' and the pass these as arguments to 'rm' which isn't
what you want (try pressing <tab> to see the expansion).
If there are a small number of files try:
rm -f **/*.o
or if the expansion will result in more file names than can be passed on the
command line:
find . -name '*.o' | xargs rm -f
-pascal

find -type f -name "*.o" -exec rm -f {} \;
Or:
rm -f **/*.o with zsh's goodies, But you'll get a "blah.o: is a
directory" message if you have directories which names end with ".o"

rm -f **/*.o(^/) will work if you've doing 'setopt EXTENDED_GLOB', too.
(That'll remove all files which end in .o recursively, and exclude all *.o
files which are directories).

Gee, this makes me look at "find" like an easy-to-use program ;)
BTW, whats the argument limit for zsh?

[advocacy] Actually, the only reason I don't know how to use find is
because of zsh. Since it's my shell wherever I'm at, I tend to type stuff
like that in all the time :). Once you've learnt the basic globbing stuff
(?, *, [], {}), the extended glob options are brilliant.. *(@) and a few
others in particular are so useful! If you don't know them yet, I'd highly
advise learning them.

I'd say
ls **/*(.)
is much easier than
find . -type f -exec ls {} \;
You just need a little bit of experience with zsh's extended globbing.
(I hardly use find any more)
YMMV :)

jean-luc@picard (tty11) ~> /bin/echo $(repeat 32767 echo -n "x " )
zsh: argument list too long: /bin/echo
Ah, the limit is at 32766 arguments. (On Linux-i386)
Here's the few situations where I need find again... :)
Question to zsh-workers (Cc-ed):
Is there a special reason why only 32766 arguments are allowed? (that
is, 32766+1, the executable name, so - an unsigned short seems to be
used for counting the arguments - why not an int? Would be 2147483646
arguments on Linux)
(I currently don't read zsh-workers, so please Cc me or zsh-users if you
reply to this question. thanks)
CU,
Thomas

This limit is not set by zsh but by the underlying libraries/OS.
Moreover (correct me if I'm wrong) it is usualy set in term of a limit
on the size of the environnement plus the size of the parameters (not
realy the number of these).

This a standard message printed from `strerror(E2BIG)' after
`execve(...)' returned the error `E2BIG' to zsh. In other words,
that's the C library speaking to you through zsh.

Well, for *you* and with this particular case of arguments list!

Since `echo' is builtin (therefore not exec'ed), you may want to do
echo PATTERN | xargs COMMAND
when `COMMAND PATTERN' don't work.

Yes, makes sense.

Right. Using different parameters, the limit (in
"number-of-arguments-allowed") was smaller.

Cool idea. *very* cool.
Perhaps I should even build a cool preexec() that handles this? Perhaps
some time in the future...

Alexandre Duret-Lutz <alexandre.duret@greyc.ismra.fr> typed:
:Since `echo' is builtin (therefore not exec'ed), you may want to do
:echo PATTERN | xargs COMMAND
I hope everyone is aware of the whitespace in name problem with above.
Note also that ``print'' is also a builtin, and if your ``xargs'' has a
``-0'' flag or similar (separate on NUL '\0' instead of whitespace)
then you should be using
% print -N PATTERN | xargs -0 COMMAND
:when `COMMAND PATTERN' don't work.
