Hello

If I open a console and type

Code: Select all

nothing happend.
Maybe I have no permission?
Why this is not stated?

blkid is a root only command. You can use:

Code: Select all

sudo blkid

or

Code: Select all

su -
blkid

Or you follow the recommendation from the blkid manpages if you don't want to use root permissions:
https://man7.org/linux/man-pages/man8/blkid.8.html

It is recommended to use lsblk(8) command to get information
about block devices, or lsblk --fs to get an overview of
filesystems, or findmnt(8) to search in already mounted
filesystems.

lsblk(8) provides more information, better control on
output formatting, easy to use in scripts and it does not
require root permissions to get actual information. blkid
reads information directly from devices and for non-root
users it returns cached unverified information. blkid is
mostly designed for system services and to test libblkid
functionality.

Thank you

root only command

Okay. Why this is not stated?

Yes that is odd.
Ask upstream.

No, it's not odd - it's already in the documentation:

DESCRIPTION
[...]blkid reads information directly from devices and for non-root users it returns cached unverified information

If there's nothing cached, then there's also no output. That is not an error.
