SYNOPSIS
|
|
========
|
|
|
|
**zbm-efi-kcl** [-f <kcl-file>] [-k <kcl-text>] [-o <output>] -e <input>
|
|
|
|
DESCRIPTION
|
|
===========
|
|
|
|
The **zbm-efi-kcl** utility allows review and manipulation of the embedded kernel command line value present in ZFSBootMenu EFI binaries. This value is used by most UEFI firmware implementations and bootloaders.
|
|
|
|
OPTIONS
|
|
=======
|
|
|
|
**-e** *input*
|
|
|
|
Define the EFI binary upon which to operate. This option is required.
|
|
|
|
**-f** *kcl-file*
|
|
|
|
Replace the embedded kernel command line with the contents of the file. This is primarily intended for automated changes to the EFI binary.
|
|
|
|
**-k** *kcl-text*
|
|
|
|
Replace the kernel command line with the quoted argument. Ensure proper shell quoting behavior is respected here.
|
|
|
|
**-o** *output*
|
|
|
|
After changing the embedded kernel command line, store the new EFI binary under a new file name. The input EFI binary is left unchanged.
|
|
|
|
If neither **-f** or **-k** are provided, the command line from the input EFI binary will be opened in ``$EDITOR``.
|
|
|
|
EXAMPLES
|
|
========
|
|
|
|
Perform an in-place edit of the commandline in the release EFI binary::
|
|
|
|
zbm-efi-kcl -e /boot/efi/EFI/BOOT/zfsbootmenu.EFI
|
|
|
|
Perform an edit and store the change in a new file::
|
|
|
|
zbm-efi-kcl -e /boot/efi/EFI/boot/zfsbootmenu.EFI -o /boot/efi/EFI/boot/zfsbootmenu-testing.EFI
