.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.
.SH ENVIRONMENT VARIABLES

\fBLVM_SYSTEM_DIR\fP
