You shouldn't require root for either blkid or lsblk, though the former needs a path, and does include a warning that the information may be read from cache. One question about lsblk, though: why does it always use the xterm width to format the output, regardless of whether you redirect the output and the value of COLUMNS. Is there a workaround beyond resizing the window? Cheers, David.
