SWAPLABEL(8) System Administration SWAPLABEL(8) NAME swaplabel - print or change the label or UUID of a swap area SYNOPSIS swaplabel [-L label] [-U UUID] device DESCRIPTION swaplabel will display or change the label or UUID of a swap partition lo- cated on device (or regular file). If the optional arguments -L and -U are not given, swaplabel will simply display the current swap-area label and UUID of device. If an optional argument is present, then swaplabel will change the appro- priate value on device. These values can also be set during swap creation using mkswap(8). The swaplabel utility allows changing the label or UUID on an actively used swap device. OPTIONS -L, --label label Specify a new label for the device. Swap partition labels can be at most 16 characters long. If label is longer than 16 characters, swapla- bel will truncate it and print a warning message. -U, --uuid UUID Specify a new UUID for the device. The UUID must be in the standard 8-4-4-4-12 character format, such as is output by uuidgen(1). -h, --help Display help text and exit. -V, --version Display version and exit. ENVIRONMENT LIBBLKID_DEBUG=all enables libblkid debug output. AUTHORS swaplabel was written by Jason Borden <jborden@bluehost.com> and Karel Zak <kzak@redhat.com>.
