NAME
mh-profile - user profile customization for nmh message handler SYNOPSIS
$HOME/.mh_profile DESCRIPTION
Each user of nmh is expected to have a file named .mh_profile in his or her home directory. This file contains a set of user parameters used by some or all of the nmh family of programs. Each entry in the file is of the format profile-component: value If the text of profile entry is long, you may extend it across several real lines by indenting the continuation lines with leading spaces or tabs. Comments may be introduced by a line starting with `#:': #: This is a comment. Blank lines are not permitted in .mh_profile. Standard Profile Entries The possible profile components are exemplified below. The only mandatory entry is `Path:'. The others are optional; some have default values if they are not present. In the notation used below, (profile, default) indicates whether the information is kept in the user's nmh profile or nmh context, and indicates what the default value is. Path: Mail Locates nmh transactions in directory "Mail". This is the only mandatory profile entry. (profile, no default) context: context Declares the location of the nmh context file. This is overridden by the environment variable $MHCONTEXT. See the HISTORY section below. (profile, default: <nmh-dir>/context) Current-Folder: inbox Keeps track of the current open folder. (context, default: folder specified by "Inbox") Inbox: inbox Defines the name of your default inbox. (profile, default: inbox) Previous-Sequence: pseq Names the sequence or sequences which should be defined as the `msgs' or `msg' argument given to any nmh command. If not present or empty, no such sequences are defined. Otherwise, for each name given, the sequence is first zero'd and then each message is added to the sequence. Read the mh-sequence(5) man page for the details about this sequence. (profile, no default) Sequence-Negation: not Defines the string which, when prefixed to a sequence name, negates that sequence. Hence, "notseen" means all those messages that are not a member of the sequence "seen". Read the mh-sequence(5) man page for the details. (profile, no default) Unseen-Sequence: unseen Names the sequence or sequences which should be defined as those messages which are unread. The commands inc, rcvstore, mhshow, and show will add or remove messages from these sequences when they are incorporated or read. If not present or empty, no such sequences are defined. Otherwise, each message is added to, or removed from, each sequence name given. Read the mh-sequence(5) man page for the details about this sequence. (profile, no default) mh-sequences: .mh_sequences The name of the file in each folder which defines public sequences. To disable the use of public sequences, leave the value portion of this entry blank. (profile, default: .mh_sequences) atr-seq-folder: 172 178-181 212 Keeps track of the private sequence called "seq" in the specified folder. Private sequences are generally used for read-only folders. See the mh-sequence(5) man page for details about private sequences. (context, no default) Editor: /usr/bin/vi Defines the editor to be used by the commands comp, dist, forw, and repl. (profile, default: /usr/bin/sensible-editor) automimeproc: If defined and set to 1, then the whatnow program will automatically invoke the buildmimeproc (discussed below) to process each mes- sage as a MIME composition draft before it is sent. (profile, no default) Msg-Protect: 600 An octal number which defines the permission bits for new message files. See chmod(1) for an explanation of the octal number. (pro- file, default: 0600) Folder-Protect: 700 An octal number which defines the permission bits for new folder directories. See chmod(1) for an explanation of the octal number. (profile, default: 700) program: default switches Sets default switches to be used whenever the mh program program is invoked. For example, one could override the "Editor:" profile component when replying to messages by adding a component such as: repl: -editor /bin/ed (profile, no defaults) lasteditor-next: nexteditor Names "nexteditor" to be the default editor after using "lasteditor". This takes effect at "What now?" prompt in comp, dist, forw, and repl. After editing the draft with "lasteditor", the default editor is set to be "nexteditor". If the user types "edit" without any arguments to "What now?", then "nexteditor" is used. (profile, no default) Folder-Stack: folders The contents of the folder-stack for the folder command. (context, no default) Local-Mailbox: Your Username <user@some.host> Tells the various MH tools what your local mailbox is. If set, will be used by the default component files by tools like comp and repl to construct your default "From" header. The text used here will be copied exactly to your From: header, so it should already be RFC-822 compliant. If this is set, the Signature profile entry is NOT used, so it should include a signature as well. (profile, default: userid@local.hostname) Alternate-Mailboxes: mh@uci-750a, bug-mh* Tells repl and scan which addresses are really yours. In this way, repl knows which addresses should be included in the reply, and scan knows if the message really originated from you. Addresses must be separated by a comma, and the hostnames listed should be the "official" hostnames for the mailboxes you indicate, as local nicknames for hosts are not replaced with their official site names. For each address, if a host is not given, then that address on any host is considered to be you. In addition, an asterisk (`*') may appear at either or both ends of the mailbox and host to indicate wild-card matching. (profile, default: your user-id) Aliasfile: aliases other-alias Indicates aliases files for ali, whom, and send. This may be used instead of the -alias file switch. (profile, no default) Draft-Folder: drafts Indicates a default draft folder for comp, dist, forw, refile, and repl. Read the mh-draft(5) man page for details. (profile, no default) digest-issue-list: 1 Tells forw the last issue of the last volume sent for the digest list. (context, no default) digest-volume-list: 1 Tells forw the last volume sent for the digest list. (context, no default) MailDrop: .mail Tells inc your maildrop, if different from the default. This is superseded by the environment variable $MAILDROP. (profile, default: /var/mail/$USER) Signature: RAND MH System (agent: Marshall Rose) Tells front-end programs such as comp, forw, and repl your mail signature. This is superseded by the environment variable $SIGNATURE. If $SIGNATURE is not set and this profile entry is not present, the "gcos" field of the /etc/passwd file will be used. Your signature will be added to the address send puts in the "From:" header; do not include an address in the signature text. The "Local-Mailbox" profile component supersedes all of this. (profile, no default) Process Profile Entries The following profile elements are used whenever an nmh program invokes some other program such as more. The .mh_profile can be used to select alternate programs if the user wishes. The default values are given in the examples. buildmimeproc: /usr/bin/mh/mhbuild This is the program used by whatnow to process drafts which are MIME composition files. fileproc: /usr/bin/mh/refile This program is used to refile or link a message to another folder. It is used by send to file a copy of a message into a folder given by a "Fcc:" field. It is used by the draft folder facility in comp, dist, forw, and repl to refile a draft message into another folder. It is used to refile a draft message in response to the refile directive at the "What now?" prompt. formatproc: Program called by mhl to filter a component when it is tagged with the "format" variable in the mhl filter. See mhl(5) for more information. incproc: /usr/bin/mh/inc Program called by mhmail to incorporate new mail when it is invoked with no arguments. installproc: /usr/lib/mh/install-mh This program is called to initialize the environment for new users of nmh. lproc: /usr/bin/sensible-pager This program is used to list the contents of a message in response to the list directive at the "What now?" prompt. It is also used by the draft folder facility in comp, dist, forw, and repl to display the draft message. mailproc: /usr/bin/mh/mhmail This is the program used to automatically mail various messages and notifications. It is used by conflict when using the -mail option. It is used by send to post failure notices. It is used to retrieve an external-body with access-type `mail-server' (such as when storing the body with mhstore). mhlproc: /usr/lib/mh/mhl This is the program used to filter messages in various ways. It is used by mhshow to filter and display the message headers of MIME messages. When the -format or -filter option is used by forw or repl, the mhlproc is used to filter the message that you are forward- ing, or to which you are replying. When the -filter option is given to send, the mhlproc is used to filter the copy of the message that is sent to "Bcc:" recipients. moreproc: /usr/bin/sensible-pager This is the program used by mhl to page the mhl formatted message when displaying to a terminal. It is also the default program used by mhshow to display message bodies (or message parts) of type text/plain. mshproc: /usr/bin/mh/msh Currently not used. packproc: /usr/bin/mh/packf Currently not used. postproc: /usr/lib/mh/post This is the program used by send, mhmail, rcvdist, and viamail (used by the sendfiles shell script) to post a message to the mail transport system. It is also called by whom (called with the switches -whom and -library) to do address verification. rmmproc: none This is the program used by rmm and refile to delete a message from a folder. sendproc: /usr/bin/mh/send This is the program to use by whatnow to actually send the message showmimeproc: /usr/bin/mh/mhshow This is the program used by show to process and display non-text (MIME) messages. showproc: /usr/lib/mh/mhl This is the program used by show to filter and display text (non-MIME) messages. whatnowproc: /usr/bin/mh/whatnow This is the program invoked by comp, forw, dist, and repl to query about the disposition of a composed draft message. whomproc: /usr/bin/mh/whom This is the program used by whatnow to determine to whom a message would be sent. Environment Variables The operation of nmh and its commands it also controlled by the presence of certain environment variables. Many of these environment variables are used internally by the "What now?" interface. It's amazing all the information that has to get passed via environment variables to make the "What now?" interface look squeaky clean to the nmh user, isn't it? The reason for all this is that the nmh user can select any program as the whatnowproc, including one of the standard shells. As a result, it's not possible to pass information via an argument list. The convention is that environment variables whose names are all upper-case are user-settable; those whose names are lower-case only are used internally by nmh and should not generally be set by the user. $MH With this environment variable, you can specify a profile other than .mh_profile to be read by the nmh programs that you invoke. If the value of $MH is not absolute, (i.e., does not begin with a "/"), it will be presumed to start from the current working directory. This is one of the very few exceptions in nmh where non-absolute pathnames are not considered relative to the user's nmh directory. $MHCONTEXT With this environment variable, you can specify a context other than the normal context file (as specified in the nmh profile). As always, unless the value of $MHCONTEXT is absolute, it will be presumed to start from your nmh directory. $MHBUILD With this environment variable, you can specify an additional user profile (file) to be read by mhbuild, in addition to the mhn.defaults profile. $MHN With this environment variable, you can specify an additional user profile (file) to be read by mhn, in addition to the mhn.defaults profile. mhn is deprecated, so this support for this variable will be removed from a future nmh release. $MHSHOW With this environment variable, you can specify an additional user profile (file) to be read by mhshow, in addition to the mhn.defaults profile. $MHSTORE With this environment variable, you can specify an additional user profile (file) to be read by mhstore, in addition to the mhn.defaults profile. $MM_CHARSET With this environment variable, you can specify the native character set you are using. You must be able to display this character set on your terminal. This variable is checked to see if a RFC-2047 header field should be decoded (in inc, scan, mhl). This variable is checked by show to see if the showproc or showmimeproc should be called, since showmimeproc will be called if a text message uses a character set that doesn't match $MM_CHARSET. This variable is checked by mhshow for matches against the charset parameter of text contents to decide it the text content can be displayed without modifications to your terminal. This variable is checked by mhbuild to decide what charac- ter set to specify in the charset parameter of text contents containing 8-bit characters. When decoding text in such an alternate character set, nmh must be able to determine which characters are alphabetic, which are con- trol characters, etc. For many operating systems, this will require enabling the support for locales (such as setting the environment variable $LC_CTYPE to iso_8859_1). $NOMHNPROC If this variable is set, show will next test for MIME messages. This mechanism is obsolete; use the -nocheckmime switch to show instead. $MAILDROP This variable tells inc the default maildrop. This supersedes the "MailDrop" profile entry. $MAILHOST This variable tells inc the POP host to query for mail to incorporate. See the inc(1) man page for more information. $USERNAME_EXTENSION This variable is for use with username_extension masquerading. See the mh-tailor(5) man page. $SIGNATURE This variable tells send and post your mail signature. This supersedes the "Signature" profile entry, and is not used when the "Local-Mailbox" profile component is set. $USER This variable tells repl your user name and inc your default maildrop: see the "MailDrop" profile entry. $HOME This variable tells all nmh programs your home directory $TERM This variable tells nmh your terminal type. The environment variable $TERMCAP is also consulted. In particular, these tell scan and mhl how to clear your terminal, and how many columns wide your terminal is. They also tell mhl how many lines long your terminal screen is. $MHMTSCONF If this variable is set to a non-null value, it specifies the name of the mail transport configuration file to use by post, inc, and other programs that interact with the mail transport system, instead of the default. See mh-tailor(5). $MHMTSUSERCONF If this variable is set to a non-null value, it specifies the name of a mail transport configuration file to be read in addition to the default. See mh-tailor(5). $MHTMPDIR $TMPDIR $TMP These variables are searched, in order, for the directory in which to create some temporary files. $MM_NOASK Setting this variable is set to 1 has the same effect as specifying the -nolist and -nopause switches to mhbuild, mhn, and mhshow. OBSOLETE: will be removed in a future version of nmh. $MHLDEBUG If this variable is set to a non-null value, mhl will emit debugging information. $MHPDEBUG If this variable is set to a non-null value, pick will emit a representation of the search pattern. $MHPOPDEBUG If this variable is set to a non-null value, msgchck and inc will display their interaction with the POP server. This mechanism is obsolete; use the -snoop switch instead. $MHWDEBUG If this variable is set to a non-null value, nmh commands that use the Alternate-Mailboxes profile entry will display debugging infor- mation about the values in that entry. $editalt This is the alternate message. This is set by dist and repl during edit sessions so you can peruse the message being distributed or replied to. The message is also available through a link called "@" in the current directory if your current working directory and the folder the message lives in are on the same UNIX filesystem. $mhdraft This is the path to the working draft. This is set by comp, dist, forw, and repl to tell the whatnowproc which file to ask "What now?" questions about. $mhaltmsg dist and repl set $mhaltmsg to tell the whatnowproc about an alternate message associated with the draft (the message being distrib- uted or replied to). $mhfolder This is the folder containing the alternate message. This is set by dist and repl during edit sessions so you can peruse other messages in the current folder besides the one being dis- tributed or replied to. The environment variable $mhfolder is also set by show, prev, and next for use by mhl. $mhdist dist sets $mhdist to tell the whatnowproc that message re-distribution is occurring. $mheditor This is set by comp, repl, forw, and dist to tell the whatnowproc the user's choice of editor (unless overridden by -noedit). $mhuse This may be set by comp. $mhmessages This is set by dist, forw, and repl if annotations are to occur. $mhannotate This is set by dist, forw, and repl if annotations are to occur. $mhinplace This is set by dist, forw, and repl if annotations are to occur. FILES
$HOME/.mh_profile The user profile or $MH Rather than the standard profile <mh-dir>/context The user context or $MHCONTEXT Rather than the standard context <folder>/.mh_sequences Public sequences for <folder> SEE ALSO
nmh(7), environ(5), mh-sequence(5) HISTORY
The .mh_profile contains only static information, which nmh programs will NOT update. Changes in context are made to the context file kept in the users nmh directory. This includes, but is not limited to: the "Current-Folder" entry and all private sequence information. Public sequence information is kept in each folder in the file determined by the "mh-sequences" profile entry (default is .mh_sequences). The .mh_profile may override the path of the context file, by specifying a "context" entry (this must be in lower-case). If the entry is not absolute (does not start with a "/"), then it is interpreted relative to the user's nmh directory. As a result, you can actually have more than one set of private sequences by using different context files. BUGS
The shell quoting conventions are not available in the .mh_profile. Each token is separated by whitespace. There is some question as to what kind of arguments should be placed in the profile as options. In order to provide a clear answer, recall command line semantics of all nmh programs: conflicting switches (e.g. -header and -noheader) may occur more than one time on the command line, with the last switch taking effect. Other arguments, such as message sequences, filenames and folders, are always remembered on the invocation line and are not superseded by following arguments of the same type. Hence, it is safe to place only switches (and their argu- ments) in the profile. If one finds that an nmh program is being invoked again and again with the same arguments, and those arguments aren't switches, then there are a few possible solutions to this problem. The first is to create a (soft) link in your $HOME/bin directory to the nmh program of your choice. By giving this link a different name, you can create a new entry in your profile and use an alternate set of defaults for the nmh command. Similarly, you could create a small shell script which called the nmh program of your choice with an alternate set of invocation line switches (using links and an alternate profile entry is preferable to this solution). Finally, the csh user could create an alias for the command of the form: alias cmd 'cmd arg1 arg2 ...' In this way, the user can avoid lengthy type-in to the shell, and still give nmh commands safely. (Recall that some nmh commands invoke others, and that in all cases, the profile is read, meaning that aliases are disregarded beyond an initial command invocation) MH.6.8 11 June 2012 MH-PROFILE(5)
