zsh-help - hints for use of zsh on grml
=======================================$reset_color

Main configuration of zsh happens in /etc/zsh/zshrc (global)
and /etc/skel/.zshrc which is copied to \$HOME/.zshrc once.
The files are part of the package grml-etc-core, if you want to
use them on a non-grml-system just get the tar.gz from
http://deb.grml.org/ or get the files from the mercurial
repository:

  http://hg.grml.org/grml-etc-core/raw-file/tip/etc/skel/.zshrc
  http://hg.grml.org/grml-etc-core/raw-file/tip/etc/zsh/zshrc

If you want to stay in sync with zsh configuration of grml
run 'ln -sf /etc/skel/.zshrc \$HOME/.zshrc' and configure
your own stuff in \$HOME/.zshrc.local. System wide configuration
without touching configuration files of grml can take place
in /etc/zsh/zshrc.local.

If you want to use the configuration of user grml also when
running as user root just run 'zshskel' which will source
the file /etc/skel/.zshrc.

For information regarding zsh start at http://grml.org/zsh/

Take a look at grml's zsh refcard:
% xpdf =(zcat /usr/share/doc/grml-docs/zsh/grml-zsh-refcard.pdf.gz)

Check out the main zsh refcard:
% $BROWSER http://www.bash2zsh.com/zsh_refcard/refcard.pdf

And of course visit the zsh-lovers:
% man zsh-lovers

You can adjust some options through environment variables when
invoking zsh without having to edit configuration files.
Basically meant for bash users who are not used to the power of
the zsh yet. :)

  \"NOCOR=1    zsh\" => deactivate automatic correction
  \"NOMENU=1   zsh\" => do not use menu completion (note: use strg-d for completion instead!)
  \"NOPRECMD=1 zsh\" => disable the precmd + preexec commands (set GNU screen title)
  \"BATTERY=1  zsh\" => activate battery status (via acpi) on right side of prompt
$bg[white]$fg[black]
Please report wishes + bugs to the grml-team: http://grml.org/bugs/
Enjoy your grml system with the zsh!$reset_color"
