Warning: how to send commands to ListProcessor

Note that all ListProcessor commands must be sent to a ListProcessor server, listproc@host.domain, for processing -- for example, to They must not be sent to a mailing list, since mail to a mailing list goes to all the subscribers to that list. Commands are sent as the body of an e-mail message to a ListProc server. ListProcessor ignores the subject line, so you may use whatever subject is useful for your purposes.

About this reference: purpose and conventions

Using ListProcessor highlights the most common commands for the CREN ListProcessor discussion-list and file-management software, also known as ListProc. Many ListProcessor commands have aliases for your convenience. (see "Additional documentation", below); a few of these aliases are noted herein.

In this reference, ListProcessor commands are shown in this typeface, with italics used for any command options and arguments which are to be replaced by the user. The minimum command abbreviations are in UPPERCASE. The actual commands are case-insensitive. For example, the command SUB is the same as sub or subscribe. Optional arguments and keywords are enclosed in brackets ([...]) and alternatives separated by a vertical bar ( | ), both of which must be omitted when the actual command is used. The list has been created for experimenting with ListProc. The term "local lists" refers to lists hosted by the ListProcessor with which you are communicating; "remote" lists are those hosted by other ListProcessors. Commands which relate to remote lists are forwarded to the appropriate ListProcessor when there is adequate information.

Additional documentation about ListProcessor

The information in Using ListProcessor may be supplemented through ListProcessor's HELP command. Printer-formatted versions of the ListProcessor User Manual and the ListProcessor User Reference Card are available in plain text, , PostScript, and RTF versions via anonymous ftp and Gopher from, along with other ListProcessor reference materials. The ListProcessor User Reference Card is also available as plain text, PostScript, and RTF. The ftp files for the User Manual are /listproc/userman for the plain-text version, and /listproc/ and ...rtf for PostScript and RTF versions, respectively; for the Card, replace "userman" by "usercard" in these file names. Set the card's orientation to landscape before printing the RTF version. Send a GET listproc userman or ...usercard command to (see Archive Commands) to get a copy of the plain-text version of the manual or card via e-mail.

LISts [local]
Lists all "visible" local lists, with a one-line description of each list.
LISts global
Lists all "visible" local lists and all remote lists known to the server, with a one line description of each list. Warning: This is a large file!
LISts local|global [keywords]
Adding keywords to the LISts command causes ListProcessor to return only those lists containing the keywords in its list-name, address, and one-line description. Multiple keywords separated by spaces are treated as a logically ANDed, i.e. only lists identified by ALL the keywords will be returned. Regular expressions (see SEArch command) may also be used to combine keywords. You must specify local or global in a LISts command if you use keywords.

Learn the purpose of a list with the Review and Information commands

REView list-name [SHOrt|DEScription|SUBscribers]
REView list-name
returns a full description of the intended purpose of the list list-name (if provided by the list owner), the attributes which determine how the list operates, and (if you're a subscriber or they're available to non-subscribers) the list of non-concealed subscribers to the list.
REView list-name SHOrt|DEScription
returns only the description of the intended purpose of the list (if available) and the attributes of the list (no subscriber information)

Joining and leaving lists with Subscribe and Unsubscribe

SUBscribe list-name your-name Alias: JOIn
adds you to the list that you specify by replacing list-name with the list-name (that part of the e-mail address of the list to the left of the @-sign). Replace your-name with your real name (up to 4 words show on a REView). ListProc gets your e-mail address from the From: header of your message. For example, if your name is Joan S. Doe, you would subscribe to the list by sending mail with the single line sub circuses Joan S. Doe as the body of an e-mail message to or your local ListProc. If your local ListProc does not know about the list circuses, it will send you a message to that effect, and you will have to send your subscription message directly to
UNSubscribe list-name Alias: SIGNOFF
removes you from the list whose list-name you specify

Setting and Querying your list options

SET list-name [option arg [args]] Alias: QUEry
With no option or arguments specified, SET list-name or QUEry list-name returns a list of all of your current subscription options for the specified list, if you are subscribed.
The MAIL option requires one of the arguments ACK, NOACK, DIGEST, or POSTPONE. The argument ACK causes ListProc to include you in the distribution of each message you send to a list; NOACK causes ListProc not to include you when you send the message. Thus, Set dummy mail ack causes you to receive a copy of each message you send to the list dummy. The DIGEST option causes you to receive your mail from the specified list in the "digest" collection of messages (including messages you sent to the list) whenever that digest is distributed. SET list-name MAIL POSTPONE causes listproc to exclude you from all list distributions until you send another set list-name mail command with one of the other arguments.
SET list-name PASsword old-password new-password
changes your list password. Your initial password, if needed, is supplied in the message you receive confirming your subscription. Subscriber passwords are case-sensitive and may contain only upper- and lower-case alphabetic characters, numbers, and the special characters hyphen, at -sign, pound-sign, colon, semicolon ( - @ # : ;).
SET list-name ADDress password new-address
change your registered e-mail address.
SET list-name CONceal YES|NO
If yes, REView list-name will NOT include your name.

Archive and File Commands

About archives: List archives and other archived files

A ListProcessor archive may contain the archives of a list discussion, in which case it will usually be replaced, in archive commands, by the list-name (though a few sites organize their list archives differently), or it may contain other files which have been stored for search and retrieval using ListProc. The optional password parameter shown in archive commands is omitted except when the specified archives have been password protected for privacy, in which case the password associated with the archive must be supplied in the commands, preceeded by a slash.

Pattern may be a single word or string, or a regular expression (see the ListProcessor User Manual) in which ^ (carat) negates whatever follows, | (vertical bar) and & (ampersand), respectively, provide logical OR and AND, < and > (lesser and greater) are used to group parts of regular expressions, and.
