.TH LVM 8 "LVM TOOLS" "Sistina Software UK" \" -*- nroff -*-
|
|
.SH NAME
|
|
lvm \- LVM2 tools
|
|
.SH SYNOPSIS
|
|
.B lvm
|
|
[command | file]
|
|
.SH DESCRIPTION
|
|
\fBlvm\fP provides the command-line tools for LVM2. A separate
|
|
manual page describes each command in detail.
|
|
.LP
|
|
If \fBlvm\fP is invoked with no arguments it presents a readline prompt
|
|
(assuming it was compiled with readline support).
|
|
LVM commands may be entered interactively at this prompt with
|
|
readline facilities including history and command name and option
|
|
completion. Refer to \fBreadline\fP(3) for details.
|
|
.LP
|
|
If \fBlvm\fP is invoked with argv[0] set to the name of a specific
|
|
LVM command (for example by using a hard or soft link) it acts as
|
|
that command.
|
|
.LP
|
|
One advantage of using the built-in shell is that configuration
|
|
information is cached internally between commands.
|
|
.LP
|
|
A file containing a simple script with one command per line
|
|
can also be given on the command line. The script can also be
|
|
executed directly if the first line is #! followed by the absolute
|
|
path of \fBlvm\fP.
|
|
