lscp1

Usage

Overview

lscp is a utility for displaying checkpoints or snapshots of the NILFS2 file system found in device. device may be a block device or a filesystem node (file or directory) on the filesystem. 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.
