Update the synopsis and description sections of the manual pages for chcp, dumpseg, lscp, lssu, mkcp, nilfs-clean, and rmcp. This reflects the recent changes allowing these tools to accept a filesystem node (file or directory) argument in place of a block device, automatically resolving the backing device via the library. Also update the version date and number to "Jan 2026" and "2.3" respectively. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@gmail.com>

.TH RMCP 8 "Jan 2026" "nilfs-utils version 2.3"
|
|
.SH NAME
|
|
rmcp \- remove NILFS2 checkpoints
|
|
.SH SYNOPSIS
|
|
.B rmcp
|
|
[\fIoptions\fP] [\fIdevice\fP|\fInode\fP] \fIcheckpoint-range\fP ...
|
|
.SH DESCRIPTION
|
|
.B rmcp
|
|
is a utility for removing checkpoints from the NILFS2 file system
|
|
found in \fIdevice\fP. The checkpoints which user wants to remove are
|
|
specified with one or more \fIcheckpoint-ranges\fP.
|
|
.I device
|
|
may be a block device or a filesystem node (file or directory) on the
|
|
filesystem.
|
|
When \fIdevice\fP
|
|
is omitted, rmcp tries to find a NILFS2 file system from
|
|
\fI/proc/mounts\fP.
|
|
.PP
|
|
The \fIcheckpoint-range\fP must be provided with one or two integers
|
|
in one of the following way:
|
|
.TP
|
|
.BR cno
|
|
single checkpoint number
|
|
.TP
|
|
.BR start..end
|
|
every checkpoint number between \fBstart\fP and \fBend\fP
|
|
.TP
|
|
.BR ..end
|
|
every checkpoint number equal or younger than \fBend\fP
|
|
.TP
|
|
.BR start..
|
|
every checkpoint number equal or greater than \fBstart\fP
|
|
.PP
|
|
This command is valid only for mounted NILFS2 file systems, and
|
|
will fail if the \fIdevice\fP has no active mounts.
|
|
