I run efibootmgr version 17 at bash command line and it prints a simple list of boot options , eg.
> efibootmgr
BootCurrent: 0000
Timeout: 1
BootOrder: 0000,0001,000B,0006,0004,000C
Boot0000* GRUB
Boot0001* Windows
Boot0004 Hard
Boot0006 Windows
Boot000B Hard
Boot000C CD/DVD

now version 18 prints a very detailed list :
> efibootmgr
BootCurrent: 0000
Timeout: 1 seconds

I think it would be good if v18 default was same as v17 ?

-u option trims output down a bit, maybe add a -s option for 'simple' output, or just revert default to same as v17

Commit 8ec3e9d changed the output format intentionally. This change broke my script that parsed the output to find existing entries by name. @vathpela, could you revert this change?

  1. Scripts that parse the output broke, because the format changed.
  2. There is not even an option to go back to the old format.
  3. The new format can't be reliably parsed. Even though the device path comes after a tab character, it's not guaranteed to be printed, so the script can't just throw away everything after the last tab. If the entry name contains a tab, and efidp_format_device_path fails, the parser will misinterpret part of the name as the device path.

I'm just noticing this behavior as well with version 18. I hope they go back to the format from version 17.

Just for anyone who is looking for a workaround since it looks like v18 will not be updated, you can use awk in an alias , or script to replicate the v17 printout :

alias ebm='awk -F"HD|BBS|Ven" "{print $1}" <(efibootmgr -u)'

Depending on your system, it might be necessary to add other awk -F delimiters.

Fix bootchooser for the output of efibootmgr 18
343c3ca 
Since efibootmgr 18, the default output of `efibootmgr` is now more
verbose [1], which breaks the assumptions made by RAUC in regards to
parsing the output. This issue is also affecting others [2].

Fix the parsing logic by unconditionally splitting on a tab in the
detected name part of the boot entry, so that the unused data part can
be discarded.
Emit a debug message for each found boot entry, as this helps in
detecting issues in the future.
