SYNOPSIS

DESCRIPTION

vol_id

print the safe version of volume label suitable for use as filename. Use -L to print literal label

-u

print the uuid of a volume

-L

EXIT STATUS

vol_id will only return successful if the value asked for is not empty. All trailing whitespace will be removed, spaces replaced by underscore and slashes ignored.
