       run-mailcap, view, see, edit, compose, print - execute programs via entries in the mailcap


       run-mailcap --action=ACTION [--option[=value]] [MIME-TYPE:[ENCODING:]]FILE [...]

       The see, edit, compose and print versions are just aliases that default to the view, edit,
       compose, and print actions (respectively).


       run-mailcap  (or  any  of  its  aliases)  will  use the given action to process each mime-
       type/file in  turn.   Each  file  is  specified  as  its  mime-type,  its  encoding  (e.g.
       compression), and filename together, separated by colons.  If the mime-type is omitted, an
       attempt to determine the type is made by trying to match the file's extension  with  those
       in the mime.types files.  If no mime-type is found, a last attempt will be done by running
       the file command, if available.  If the encoding is omitted, it will  also  be  determined
       from  the  file's  extensions.   Currently supported encodings are gzip (.gz), bzip (.bz),
       bzip2 (.bz2), and compress (.Z).  A filename of "-" can be used to mean "standard  input",
       but then a mime-type must be specified.

       Both  the  user's  files  (~/.mailcap;  ~/.mime.types) and the system files (/etc/mailcap;
       /etc/mime.types) are searched in turn for information.

       All options are in the form --<opt>=<value>.

              Performs the specified action on the files.  Valid actions are view, cat (uses only
              "copiousoutput" rules and sends output to STDOUT) , compose, composetyped, edit and
              print.  If no action is specified, the action will be determined by how the program
              was called.

              Turns on extra information to find out what is happening.

              Ignores any "copiousoutput" directive and sends output to STDOUT.

              Displays the found command without actually executing it.


       A  temporary  copy  of  the  file  is  opened  if  the  file name matches the Perl regular
       expresssion "[^[:alnum:],.:/@%^+=_-]", in order to protect from  the  injection  of  shell
       commands,  and  to  make sure that the name can always be displayed in the current locale.
       In addition, the file is opened using its  absolute  path  to  prevent  the  injection  of
       command-line arguments, for instance using file names starting with dashes.
