Try it yourself
An example you can run in a temporary verification environment.
lsblk -o NAME,FSTYPE,PARTTYPENAME,MOUNTPOINTS 2>/dev/null | headExpected result
ブロックデバイス情報。UEFI環境ではEFI System等が見える場合があるKey points
- ESP is for UEFI
- It is normally FAT-formatted
- It may be mounted at /boot/efi
Notes
- Environment: Linux / UEFI・util-linux lsblk
- Command output formatting can vary slightly by distribution or tool version.
- Run the example in a temporary directory or process when possible.
