8 # Ported to support git "mbox" format files by Ryan Anderson <ryan@michonline.com>
10 # Sends a collection of emails to the given email addresses, disturbingly fast.
12 # Supports two formats:
13 # 1. mbox format files (ignoring most headers and MIME formatting - this is designed for sending patches)
14 # 2. The original format support by Greg's script:
15 # first line of the message is who to CC,
16 # and second line is the subject of the message.

40 git-send-email [options] <file | directory>...
42 --from Specify the "From:" line of the email to be sent.
44 --to Specify the primary "To:" line of the email.
46 --cc Specify an initial "Cc:" list for the entire series
49 --bcc Specify a list of email addresses that should be Bcc:
52 --compose Use \$EDITOR to edit an introductory message for the
55 --subject Specify the initial "Subject:" line.
56 Only necessary if --compose is also set. If --compose
57 is not set, this will be prompted for.
59 --in-reply-to Specify the first "In-Reply-To:" header line.
60 Only used if --compose is also set. If --compose is not
61 set, this will be prompted for.
63 --chain-reply-to If set, the replies will all be to the previous
64 email sent, rather than to the first email sent.
67 --no-signed-off-cc Suppress the automatic addition of email addresses
68 that appear in Signed-off-by: or Cc: lines to the cc:
69 list. Note: Using this option is not recommended.
71 --smtp-server If set, specifies the outgoing SMTP server to use.
72 Defaults to localhost.
74 --suppress-from Suppress sending emails to yourself if your address
75 appears in a From: line.
77 --quiet Make git-send-email less verbose. One line per email
78 should be all that is output.
