===== Examples =====

=== Show script's own URI ===

    #!ipxe
    
    echo This script was loaded from ${cwuri}
    echo This script is in the directory ${cwduri}

=== Boot Fedora installer ===

    initrd images/pxeboot/initrd.img
    boot

===== Description =====

Represents the directory portion of the current working URI, i.e. the base URI relative to which any relative URIs will be resolved.

===== See also =====

  * ''[[:cfg:cwuri]]''
  * [[:cfg|List of all iPXE settings]]

===== Notes =====

When executing an iPXE [[:scripting|script]], the current working URI is set to the URI of the script itself.  This allows the script to download subsequent files using relative paths, which will be interpreted as being relative to the script's own URI.

You can use the ''cwduri'' setting to construct URI strings that can be passed to the booted operating system via its own command line.  For example, suppose that you have a web server containing a Fedora distribution mirror, and a script that allows the user to select a version to be installed:

    #!ipxe
    
    menu Select Fedora version
    item 38 Fedora 38
    item 39 Fedora 39
    item 40 Fedora 40
    choose fedver
    
    set repo ${cwduri}/releases/${fedver}/Everything/x86_64/os
    kernel ${repo}/images/pxeboot/vmlinux inst.repo=${repo}
    initrd ${repo}/images/pxeboot/initrd.img
    boot
