MARK(1) General Commands Manual MARK(1) NAME mark - manipulate nmh message sequences SYNOPSIS mark [-help] [-version] [+folder] [msgs] [-sequence name ...] [-add | -delete | -list] [-public | -nopublic] [-zero | -nozero] [-empty | -noempty] [-range | -norange] DESCRIPTION The mark command manipulates message sequences by adding or deleting mes- sage numbers from folder-specific message sequences, or by listing those sequences and messages. A message sequence is a keyword, just like one of the "reserved" message names, such as "first" or "next". Unlike the "reserved" message names, which have a fixed semantics on a per-folder basis, the semantics of a mes- sage sequence may be defined, modified, and removed by the user. Message sequences are folder-specific, e.g., the sequence name "seen" in the con- text of folder "+inbox" need not have any relation whatsoever to the se- quence of the same name in a folder of a different name. Three action switches direct the operation of mark. These switches are mu- tually exclusive: the last occurrence of any of them overrides any previous occurrence of the other two. The -add switch tells mark to add messages to sequences or to create a new sequence. For each sequence named via the -sequence name argument (which must occur at least once) the messages named via msgs (which defaults to "cur" if no msgs are given), are added to the sequence. The messages to be added need not be absent from the sequence. If the -zero switch is speci- fied, the sequence will be emptied prior to adding the messages. Hence, -add -zero means that each sequence should be initialized to the indicated messages, while -add -nozero means that each sequence should be appended to by the indicated messages. The -empty switch does not affect the operation of -add. The -delete switch tells mark to delete messages from sequences, and is the dual of -add. For each of the named sequences, the named messages are re- moved from the sequence. These messages need not be already present in the sequence. If the -zero switch is specified, then all messages in the folder are added to the sequence (first creating the sequence, if neces- sary) before removing the messages. Hence, -delete -zero means that each sequence should contain all messages except those indicated, while -delete -nozero means that only the indicated messages should be removed from each sequence. As expected, the command "mark -sequence foo -delete all" emp- ties the sequence "foo", and therefore removes that sequence from the cur- rent folder's list of sequences. Sequence foo must exist or a "no such se- quence" error results. This can be avoided by adding -zero: "mark -se- quence foo -delete -zero all" ensures sequence foo no longer exists. The -empty switch does not affect the operation of -delete. When creating or modifying sequences, you can specify the switches -public or -nopublic to force the new or modified sequences to be "public" or "pri- vate". The switch -public indicates that the sequences should be made "public". These sequences will then be readable by all nmh users with per- mission to read the relevant folders. In contrast, the -nopublic switch indicates that the sequences should be made "private", and will only be ac- cessible by you. If neither of these switches is specified, then existing sequences will maintain their current status, and new sequences will de- fault to "public" if you have write permission for the relevant folder. Check mh-sequence(5) for more details about the difference between "public" and "private" sequences. The -list switch tells mark to list all sequences, and the messages associ- ated with them. The output can be limited to just certain sequences (with -sequence switches) and/or messages (with msgs arguments). Normally, -list will show all sequences associated with the folder, or all sequences given with -sequence. Using -noempty will suppress any which would show as empty, whether because they actually are empty, or because they don't in- clude any of the given msgs, or because they've been specified with -se- quence but don't exist. (-empty is the default.) With the default -range switch, mark will compress consecutive runs of message numbers to save space. That is, "3 4 5 6" will be shown as the range "3-6". With -nor- ange, lists will be fully enumerated. The -zero switch does not affect the operation of -list. The restrictions on sequences are: * The name used to denote a message sequence must consist of an alphabetic character followed by zero or more alphanumeric characters, and cannot be one of the (reserved) message names "new", "first", "last", "all", "next", or "prev". * Message ranges with user-defined sequence names are restricted to the form "name:n", "name:+n", or "name:-n", and refer to the first or last `n' messages of the sequence `name'. If `=' is substituted for `:', these forms will instead refer to single messages positioned `n' away from one end or the other of the sequence. Constructs of the form "name1-name2" are forbidden for user defined sequences. FILES $HOME/.mh_profile The user's profile. PROFILE COMPONENTS Path: To determine the user's nmh directory. Current-Folder: To find the default current folder. SEE ALSO flist(1), pick(1), mh-sequence(5) DEFAULTS +folder The current folder. -add If -sequence is specified, -list otherwise. msgs The current message, or all if -list is specified. -nozero CONTEXT If a folder is given, it will become the current folder. HELPFUL HINTS Use flist to find folders with a given sequence, and "pick sequence -list" to enumerate those messages in the sequence (such as for use by a shell script). nmh-1.8+dev 2021-05-01 MARK(1)
