|
5 # Purpose: To be called by mutt as indicated by .mailcap to handle mail attachments.
|
|
|
6 #
|
|
|
7 # Function: Copy the given file to a temporary directory so mutt
|
|
|
8 # Won't delete it before it is read by the application.
|
|
|
9 #
|
|
|
10 # Along the way, discern the file type or use the type
|
|
|
11 # That is given.
|
|
|
12 #
|
|
|
13 # Finally use 'open' or 'open -a' if the third argument is
|
|
|
14 # given.
|
|
|
15 #
|
|
|
16 #
|
|
|
17 # Arguments:
|
|
|
18 #
|
|
|
19 # $1 is the file
|
|
|
20 # $2 is the type - for those times when file magic isn't enough.
|
|
|
21 # I frequently get html mail that has no extension
|
|
|
22 # and file can't figure out what it is.
|
|
|
23 #
|
|
|
24 # Set to '-' if you don't want the type to be discerned.
|
|
|
25 # Many applications can sniff out the type on their own.
|
|
|
26 # And they do a better job of it too.
|
|
|
27 #
|
|
|
28 # Open Office and MS Office for example.
|
|
|
29 #
|
|
|
30 # $3 is open with. as in open -a 'open with this .app' foo.xls
|
|
|
31 #
|
|
|
32 # Examples: These are typical .mailcap entries which use this program.
