NAME¶

chcp - change mode of NILFS2 checkpoints

chcp [options] cp | ss [device|node] checkpoint-number ...

DESCRIPTION¶

chcp is a utility to change the mode of the given checkpoints for the NILFS2 file system found in device. device may be a block device or a filesystem node (file or directory) on the filesystem. chcp changes checkpoints to snapshots, or vice versa. The target checkpoints are specified with one or more checkpoint numbers. When device is omitted, it tries to find a NILFS2 file system from /proc/mounts.

This command is valid only for mounted NILFS2 file systems, and will fail if the device has no active mounts.
