mailcap.order
MAILCAP.ORDER(5) Order Mailcap Entries MAILCAP.ORDER(5)
NAME
/etc/mailcap.order - the mailcap ordering specifications
DESCRIPTION
The order of entries in the /etc/mailcap file can be altered by editing the /etc/mailcap.order file. Each line of that file specifies a
package and an optional mime type. Mailcap entries that match will be placed in the order of this file. Entries that don't match will be
placed later.
Example
mime-support:*/*
gv:application/postscript
netscape:text/html
less:text/*
emacs:text/*
The above would make any entries provided by the mime-support package (as found in the /usr/lib/mime/packages directory) take priority over
everything else. The gv package will be used over anything else when it comes to postscript documents. Netscape will be used for any html
documents and less will be used for any remaining text documents. However, since neither netscape or less provide for editing documents,
any edit or compose actions will fall through to the emacs rules.
After modifying this file, be sure to run /usr/sbin/update-mime (as root) to propagate the changes into the /etc/mailcap file.
Remember that this files takes package names and not executable names. If you want to define rules that reference specific programs, the
best way is to include them in ~/.mailcap or the user section of the /etc/mailcap file.
LIMITATIONS
There is currently no way to break out a certain type from a wildcard rule. If, for example, both xv and gimp were to specify "image/*"
rules, it isn't possible to use xv for gif images but use gimp for jpeg images.
Also, I would like to add the ability to specify certain actions in the rules. For example, if netscape were to have an edit rule but I
wanted to use emacs for editing/creating html documents, I could place a line like
emacs:text/* action=edit|compose
before the netscape entry. The update-mime program would then spit out entries such that netscape view rule comes before the emacs view
rule but have the netscape edit rule comes after the emacs edit rule.
