install-mh

INSTALL-MH(8)							     [nmh-1.5]							     INSTALL-MH(8)

NAME

       install-mh - initialize the nmh environment

SYNOPSIS

       /usr/lib/mh/install-mh [-auto] [-check] [-version] [-help]

DESCRIPTION

       Install-mh  is  the  nmh program to create the initial setup for a first-time nmh user.	Install-mh lives in two places for historical rea-
       sons.

       The -auto option does things as automatically as possible and makes install-mh less chatty.

       The user is asked for the name of the directory that will be designated as the user's nmh directory.  If this directory does not exist, the
       user  is  asked	if  it should be created.  Normally, this directory should be under the user's home directory, and has the default name of
       ``Mail''.  Install-mh writes an initial .mh_profile for the user.

       As with all nmh commands, install-mh first checks for the existence of the $MH environment variable since that gives the  profile  path	if
       set.   If  it isn't set, the $HOME environment variable is consulted to determine the user's home directory.  If $HOME is not set, then the
       /etc/passwd file is consulted.

       When creating the users initial .mh_profile, install-mh will check for the existence of a global profile  /etc/nmh/mh.profile.	If  found,
       this will be used to initialize the new .mh_profile.

       The  -check  option can be used to check whether or not nmh has been installed.	This can be used by other programs to determine whether or
       not nmh has been installed without their having to know the internals of nmh.

FILES

       $HOME/.mh_profile	  The user profile
       /etc/nmh/mh.profile	  Used to initialize user profile

PROFILE COMPONENTS

       Path:		    To set the user's nmh directory

CONTEXT

       With -auto, the current folder is changed to "inbox".
