rmcp - remove NILFS2 checkpoints

SYNOPSIS

rmcp [options] [device] checkpoint-range ...

DESCRIPTION

rmcp is a utility for removing checkpoints from the NILFS2 file system found in device. The checkpoints which user wants to remove are specified with one or more checkpoint-ranges. When device is omitted, rmcp tries to find a NILFS2 file system from /proc/mounts.

The checkpoint-range must be provided with one or two integers in one of the following way:

cno: single checkpoint number
start..end: every checkpoint number between start and end
..end: every checkpoint number equal or younger than end
start..: every checkpoint number equal or greater than start

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

OPTIONS

-f, --force: Ignore snapshots or nonexistent checkpoints.
-i, --interactive: Prompt before any removal.
-h, --help: Display help message and exit.
-V, --version: Display version and exit.
