RUN-MAILCAP(1)                         Run Mailcap Programs                        RUN-MAILCAP(1)

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

SYNOPSIS
       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).

DESCRIPTION
       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.  compres‐
       sion),  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.

   EXAMPLES
         see picture.jpg
         print output.ps.gz
         compose text:index.htm
         extract-mail-attachment msg.txt | see image/tiff:gzip:-

   OPTIONS
       All options are in the form --=.

       --action=
              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.

       --debug
              Turns on extra information to find out what is happening.

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

       --norun
              Displays the found command without actually executing it.

SECURITY
       A  temporary copy of the file is opened if the file name matches the Perl regular express‐
       sion "[^[: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 addi‐
       tion, the file is opened using its absolute path to prevent the injection of  command-line
       arguments, for instance using file names starting with dashes.
