What other shells does it work? The `arg list too long' message comes from
the OS. If the arg list is long execve fails and sets errno to E2BIG.
Builtin zsh commands can have arbitrary long argument lists. If you do not
believe me, grep the zsh source for the arg list too long message. You won't
find it. The maximum allowed length of the argument list is very OS
dependent. E.g. on Linux I can do:
bolyai /l/src % /bin/echo ([nzk]|t[^au])*/**/*|wc
1 4346 127155
But here 128k is the maximum. On Ultrix and probably on other OS'es as well
the limit is much lower.
Note that you must use /bin/echo above since the echo builtin can have any
number of arguments.
Cheers,
Zoltan
