       mark - manipulate message sequences


       mark [+folder] [msgs] [-sequence name ...]  [-add | -delete] [-list]
            [-public | -nopublic] [-zero | -nozero] [-version] [-help]


       The mark command manipulates message sequences by  adding  or  deleting
       message  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 message sequence may be defined, modified, and removed
       by the user.  Message sequences are folder-specific, e.g., the sequence
       name  “seen”  in  the  context  of  folder  “+inbox”  need not have any
       relation whatsoever to the sequence of the same name in a folder  of  a
       different name.

       Three action switches direct the operation of mark.  These switches are
       mutually 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 specified, 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 -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  removed  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 necessary) 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” deletes the sequence “foo” from the  current

       When  creating  or  modifying  sequences,  you can specify the switches
       -public or -nopublic to force the  new  or  modified  sequences  to  be
       “public” or “private”.  The switch -public indicates that the sequences
       should be made “public”.  These sequences will then be readable by  all
       nmh  users  with permission to read the relevant folders.  In contrast,
       the -nopublic switch  indicates  that  the  sequences  should  be  made
       “private”,  and  will  only  be accessible by you.  If neither of these
       switches is specified, then  existing  sequences  will  maintain  their
       current  status, and new sequences will default to “public” if you have
       write permission for the relevant folder.  Check the mh-sequence(5) man
       page  for  more  details  about  the  difference  between  “public” and
       “private” sequences.

       The -list switch tells mark to list both the sequences defined for  the
       folder  and  the  messages  associated with those sequences.  Mark will
       list the name of each sequence given by -sequence name and the messages
       associated  with  that sequence.  If the sequence is private, this will
       also be indicated.  If  no  sequence  is  specified  by  the  -sequence
       switch,  then  all sequences for this folder will be listed.  The -zero
       switch does not affect the operation of -list.

       The current 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”.

       · Only a certain number of sequences may be defined for a given folder.
         This number is usually limited to 26 (10 on small systems).

       · 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',  respectively.   Constructs
         of the form “name1-name2” are forbidden for user defined sequences.


       $HOME/.mh_profile          The user profile


       Path:                To determine the user's nmh directory
       Current-Folder:      To find the default current folder


       flist(1), pick(1), mh-sequence(5)


       `+folder' defaults to the current folder
       `-add' if -sequence is specified, -list otherwise
       `msgs' defaults to cur (or all if -list is specified)


       If a folder is given, it will become the current folder.


       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).
