zsh x bash: history file

zsh x bash: history file

[Luciano ES]

	I've looked almost everywhere and can't find the use of a history file in
ZSH. Is there such thing?

	I also notice that some bash scripts won't run in zsh. There must be fatal
differences in their syntaxes. Do you know if they are documented anywhere?

	Thanks,

Well no, sorry. ;-)

Unfortunately zsh is missing solmething like bash's "histignore".

zsh can emulate certain other shells sh, ksh, csh. Many people have 
problems because of "shwordsplit".
