.TH mh 1mh.SH Namemh \- introduction to MH.SH Description.NXR "mh summary".NXR "MH overview"MH is the name of a powerful message handling system.Rather than being a single comprehensive program,MH consists of a collection of fairly simple single-purpose programs to send, receive, save, and retrieve messages.  Refer to the individual MH reference pages for descriptions of the programs that make up MH..PPUnlike .PN mail ,MH is not a closed system which must be explicitly run,and then exited when you wish to return to the shell.Instead, you may freely intersperse MH commands with other shell commands.This allows you to read and answer your mail while you have (for example) a compilation running,or are searching for a file or running programs to find an answer to someone's question before replying to them..PPTo get started using MH,add the directory.PN /usr/bin/mhto your \f(CW$PATH\fR.This is best done in one of the files.PN \&.profile , .PN \&.login ,or .PN \&.cshrcin your home directory.Check the manual entry for the shell you useif you do not know how to do this.Run the .PN inccommand.If youhave never used MH before,it creates the necessary default files and directories after asking you if you wish it to do so.The .PN inccommand moves mail from your system maildrop into your MH.PN +inboxfolder.  Each message is converted to MH format,and stored as separate files in your.PN +inbox folder until you have read it.  When you have read a message, you can refile it in another folder that you have created..PPFolders are directories in which messages are stored: the folders themselves are stored in your Mail directory.  See.MS refile 1mhand .MS folder 1mhfor more details..PPFor each message it processes,.PN incprints a one-line display.The one-line displaycontains the \f(CWFrom:\fR field, the \f(CWSubject:\fR field,and as much of the first line of the message as it can accommodate.The first message that .PN inc processes becomes your current message.  All MH commands operate on the current messageunless you have specified the.I msgargument..PPYouneed to run .PN inceach time you wish to incorporate new mailinto your .PN +inboxfolder..PPThe .PN scancommand prints a list of the messages in your current folder..PPThe commands.PN show , .PN next ,and .PN prevare used to read specific messages from the current folder.Of these,.PN showdisplays the current message.  You can also display a specific message by specifying its number.In the following example, the mail system displaysthe contents of message number 10 in the current folder:.EX% \f(CBshow 10.EE.PPThe commands.PN nextand .PN prevdisplay the message numerically following and numerically preceding the current message, respectively.In all cases, the message displayed becomes the current message.If there is no current message,.PN showmay be called with an argument, or .PN nextmay be used to advance to the first message.The command.PN rmm(remove message) deletes the current message..PPYou can delete messages other than the current message by specifying themessage number or numbers.  When you specify more than one message,you separate each message number by a space. In the following example, messages 2, 4 and 6 in the current folder are deleted:.EX% \f(CBrmm 2 4 6.EE.PPThe command.PN replis used to reply to a message.It places you in the editor with a prototype response form.While you are in the editor,you may view the item you are responding to by reading the file .PN @ ..PPThe .PN compcommand allows you to compose a message by putting you in the editor ona blank message header form,and then lets you send it..PPAll the MH commands may be run with the single argument.BR \-help ,which causes them to print a list of the arguments with which they may be invoked..PPCommands which take a message number as an argument(\c.PN scan , .PN show , .PN repl ,for example)also take one of the following keywords:.\".TP 10\f(CWfirst\fRThe first message in the current folder..\".TP \f(CWlast\fRThe last message in the current folder..\".TP\f(CWcur\fRThe current message in the current folder..\".TP \f(CWprev\fRThe previous message in the current folder..\".TP\f(CWnext\fRThe next message in the current folder..\".PPCommands which take a range of message numbers, such as .PN rmm , .PN scan , or .PN show ,also take any of the following abbreviations:.\".TP 10\fInum1\f(CW-\fInum2\fRIndicates all messages in the range \fInum1\fR to \fInum2\fR, inclusive. The specified range must contain at least one message..\".IP \fInum\f(CW:+\fIn\fR.PD 0.IP \fInum\f(CW:-\fIn\fR.PDUp to \fIn\fR messages beginning with (or ending with) message \fInum\fR.The value of \fInum\fR may be any of the MH message keywords:.PN first , .PN prev , .PN cur , .PN nextor.PN last ..\".IP \f(CWfirst:\fIn\fR.PD 0.IP \f(CWprev:\fIn\fR.PD 0.IP \f(CWnext:\fIn\fR.PD 0.IP \f(CWlast:\fIn\fR.PDThe first, previous, next or last \fIn\fR messages, if they exist..\".PPThere are many other possibilities, such as creating multiple folders for different topics, and automatically refiling messages according to subject,source, destination, or content.
