efi_rm — remove an EFI file


efi_rm [-d devicefile] file


efi_rm removes an EFI file.

The EFI file system is based on the FAT file system and used by the Itanium-based system BIOS to locate an HP-UX bootloader. See efi(4).

devicefile should be the device file for the EFI volume.

If file is a directory, efi_rm prints a diagnostic message and returns without removing the directory; use efi_rmdir(1M) to remove EFI directories. file should be relative to the root of the EFI volume specified by devicefile, not to an HP-UX file system.


efi_rm recognizes the following option:

-d devicefile

devicefile is the device special file of the EFI file system from which the file is to be removed. Without the -d option, efi_rm uses the device file specified in the environment variable EFI_PARTITION if it is defined. The -d option overrides the EFI_PARTITION environment variable.


efi_rm returns exit code 0 if the file is removed successfully. Otherwise it prints a diagnostic message and returns nonzero.


Successful completion.


Error condition occurred.


Remove bootfile from /hp-ux/efi/ of device file /dev/rdsk/c1t4d0s1, which contains an EFI file system:

efi_rm -d /dev/rdsk/c1t4d0s1 /hp-ux/efi/bootfile

Remove bootfile from /hp-ux/efi/ of persistent device file /dev/rdisk/disk7_p1 (see intro(7)), which contains an EFI file system:

efi_rm -d /dev/rdisk/disk7_p1 /hp-ux/efi/bootfile


efi_rm was developed by HP.
