lscp - list NILFS2 checkpoints

       Koji Sato

lscp is part of the nilfs-utils package and is available from https://nilfs.sourceforge.io.

       NILFS2 in Linux kernel version 2.6.38 and earlier does not support the block count (BLKCNT) information.

lscp  is  a  utility  for  displaying checkpoints or snapshots of the NILFS2 file system found in device.
       When device is omitted, /proc/mounts is examined to find a NILFS2 file system.

       This command will fail if the device has no active mounts of a NILFS2 file system.

       Every line of the lscp output consists of the following seven fields:

       CNO    Checkpoint number.

       DATE   Creation date.

       TIME   Creation time.

       MODE   Mode of the checkpoint; cp for a plain checkpoint, and ss for a snapshot.

       FLG    Flags on the checkpoint. At present, character ``i'' is printed in the field if the checkpoint was
              created only by garbage collection, checkpoint mode change, or other  change  of  internal  state.
              Otherwise ``-'' is printed.

       NBLKINC(optional)
              Number of blocks appended by the checkpoint.  This field is displayed instead of BLKCNT field when
              -g option is specified.

       BLKCNT Number of blocks used by the checkpoint.

       ICNT   Number of inodes included in the entire file system at the time specified by the checkpoint.
