NAME

       notmuch-tag - add/remove tags for all messages matching the search terms

SYNOPSIS

       notmuch tag [options...] +<tag>|-<tag> [...] [--] <search-term> [...]

       notmuch tag --batch [ --input=<filename> ]

DESCRIPTION

       Add/remove tags for all messages matching the search terms.

       See notmuch-search-terms(7) for details of the supported syntax for <search-term>.

       Tags  prefixed by '+' are added while those prefixed by '-' are removed. For each message,
       tag changes are applied in the order they appear on the command line.

       The beginning of the search terms is recognized by the first  argument  that  begins  with
       neither  '+'  nor  '-'.  Support  for  an initial search term beginning with '+' or '-' is
       provided by allowing the user to specify a "--" argument to separate  the  tags  from  the
       search terms.

       notmuch   tag   updates   the   maildir   flags   according   to   tag   changes   if  the
       maildir.synchronize_flags configuration  option  is  enabled.  See  notmuch-config(1)  for
       details.

       Supported options for tag include

           --remove-all

               Remove  all  tags  from each message matching the search terms before applying the
               tag changes appearing on the command line. This means setting  the  tags  of  each
               message  to  the  tags to be added. If there are no tags to be added, the messages
               will have no tags.

           --batch

               Read batch tagging operations from  a  file  (stdin  by  default).  This  is  more
               efficient than repeated notmuch tag invocations. See TAG FILE FORMAT below for the
               input format. This option is not compatible with specifying tagging on the command
               line.

           --input=<filename>

               Read input from given file, instead of from stdin. Implies --batch.

TAG FILE FORMAT

       The input must consist of lines of the format:

       +<tag>|-<tag> [...] [--] <query>

       Each line is interpreted similarly to notmuch tag command line arguments. The delimiter is
       one or more spaces ' '. Any characters in <tag> may be hex-encoded with %NN  where  NN  is
       the  hexadecimal value of the character. To hex-encode a character with a multi-byte UTF-8
       encoding, hex-encode each byte.  Any spaces in <tag>  must  be  hex-encoded  as  %20.  Any
       characters that are not part of <tag> must not be hex-encoded.

       In  the future tag:"tag with spaces" style quoting may be supported for <tag> as well; for
       this reason all double quote characters in <tag> should be hex-encoded.

       The <query> should be quoted using Xapian boolean term quoting rules: if a  term  contains
       whitespace  or  a close paren or starts with a double quote, it must be enclosed in double
       quotes (not including any prefix) and double quotes inside the term must be  doubled  (see
       below for examples).

       Leading  and  trailing  space ' ' is ignored. Empty lines and lines beginning with '#' are
       ignored.

   EXAMPLE
       The following shows a valid input to batch tagging. Note that only the isolated  '*'  acts
       as a wildcard. Also note the two different quotings of the tag space in tags
              +winner *
              +foo::bar%25 -- (One and Two) or (One and tag:winner)
              +found::it -- tag:foo::bar%
              # ignore this line and the next

              +space%20in%20tags -- Two
              # add tag '(tags)', among other stunts.
              +crazy{ +(tags) +&are +#possible -- tag:"space in tags"
              +match*crazy -- tag:crazy{
              +some_tag -- id:"this is ""nauty)"""
