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


run-mailcap −−action=<action> [−−debug=<value>] [<mime-type>:[<encoding>:]]<filename> [...]

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

You can make this your default pager and/or editor by adding the following to your shell startup:

shell file line(s) to add
~~~~~ ~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
sh ~/.profile PAGER=/usr/bin/see; export PAGER
EDITOR=/usr/bin/edit; export EDITOR
csh ~/.login setenv PAGER /usr/bin/see
setenv EDITOR /usr/bin/edit


run-mailcap (or any of its aliases) will use the given action to process each mime-type/file in turn. Each file is is specified as its mime-type, its encoding (eg. 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 the encoding is omitted, it will also be determined from the file’s extensions. Currently supported encodings are gzip (.gz) and compress (.Z). A filename of "-" can be used to mean "standard input", but then a mime-type must be specied.

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

print output.ps.gz
compose text/html:index.html

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

Performs the specified action on the files. Valid actions are view, 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. Any value other than zero (0) will turn on debugging output.
