It\ncan determine the type of content (e.g., filesystem or swap) that a block device holds, and\nalso the attributes (tokens, NAME=value pairs) from the content metadata (e.g., LABEL or UUID\nfields).\n\n## Sections\n\n- **NAME**\n- **SYNOPSIS**\n- **DESCRIPTION** (1 subsections)\n- **OPTIONS** (20 subsections)\n- **EXIT STATUS**\n- **CONFIGURATION FILE**\n- **ENVIRONMENT**\n- **AUTHORS**\n- **SEE ALSO**\n- **REPORTING BUGS**\n- **AVAILABILITY**\n\nUse structuredContent.sections for detailed options, examples, and full documentation.\n"

It is possible to\nspecify multiple device arguments on the command line. If none is given, all partitions or\nunpartitioned devices which appear in /proc/partitions are shown, if they are recognized.\n\nblkid has two main forms of operation: either searching for a device with a specific\nNAME=value pair, or displaying NAME=value pairs for one or more specified devices.\n\nFor security reasons blkid silently ignores all devices where the probing result is\nambivalent (multiple colliding filesystems are detected). The low-level probing mode (-p)\nprovides more information and extra exit status in this case. It’s recommended to use\nwipefs(8) to get a detailed overview and to erase obsolete stuff (magic strings) from the\ndevice.\n"

Default is \"yes\".\n\nCACHEFILE=<path>\nOverrides the standard location of the cache file. This setting can be overridden by the\nenvironment variable BLKIDFILE. Default is /run/blkid/blkid.tab, or /etc/blkid.tab on\nsystems without a /run directory.\n\nEVALUATE=<methods>\nDefines LABEL and UUID evaluation method(s). Currently, the libblkid library supports the\n\"udev\" and \"scan\" methods. More than one method may be specified in a comma-separated\nlist. Default is \"udev,scan\". The \"udev\" method uses udev /dev/disk/by-* symlinks and the\n\"scan\" method scans all block devices from the /proc/partitions file.\n",
