    <title>Introduction to ZSH</title>

    <para>The <application>ZSH</application> package contains a command
    interpreter (shell) usable as an interactive login shell and as
    a shell script command processor. Of the standard shells,
    <application>ZSH</application> most closely resembles
    <application>KSH</application> but includes many enhancements.</para>

    <note>
      <para>This version of <application>ZSH</application> is a development
      release.  The BLFS staff has determined that it provides a stable
      program which works properly with multibyte locales (e.g., UTF-8).
      To find the current stable release, refer to the
      <ulink url="http://www.zsh.org/">ZSH home page</ulink> and compile
      <application>ZSH</application> with the same instructions.</para>

    directory. Omit these parameters if you wish to retain historical
    compatibility by having all the files located in the
    <filename class='directory'>/etc</filename> directory.</para>

    <para><parameter>--bindir=/bin</parameter>: This parameter places the
    <command>zsh</command> binaries into the root filesystem.</para>

    <para><parameter>--enable-cap</parameter>: This parameter enables
    POSIX capabilities.</para>

    <para><parameter>--disable-gdbm</parameter>: This parameter disables the
    use of the <application>GDBM</application> library.</para>

      <para>Linking <application>ZSH</application> dynamically against
      <application>PCRE</application> and/or <application>GDBM</application>
      produces runtime dependencies on <filename class='libraryfile'>
      libpcre.so</filename> and/or <filename class='libraryfile'>libgdbm.so
      </filename>respectively, which both reside in
      <filename class='directory'>/usr</filename> hierarchy. If
      <filename class='directory'>/usr</filename> is a separate mount point
      and <application>ZSH</application> needs to be available in boot time,
      then its supporting libraries should be in
      <filename class='directory'>/lib</filename> too. You can move the
      libraries as follows:</para>

<screen role="root"><userinput>mv -v /usr/lib/libpcre.so.* /lib &amp;&amp;
ln -v -sf ../../lib/libpcre.so.0 /usr/lib/libpcre.so

mv -v /usr/lib/libgdbm.so.* /lib &amp;&amp;
ln -v -sf ../../lib/libgdbm.so.3 /usr/lib/libgdbm.so</userinput>
</screen>

      <para>Alternatively you can statically link <application>ZSH</application>
      against <application>PCRE</application> and <application>GDBM</application>
      if you modify the <filename>config.modules</filename> file (you need first
      to run configure to generate it).</para>
