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.

41 git-send-email [options] <file | directory>...
42 Options:
43 --from Specify the "From:" line of the email to be sent.
45 --to Specify the primary "To:" line of the email.
47 --cc Specify an initial "Cc:" list for the entire series
48 of emails.
50 --cc-cmd Specify a command to execute per file which adds
51 per file specific cc address entries
53 --bcc Specify a list of email addresses that should be Bcc:
54 on all the emails.
56 --compose Use \$GIT_EDITOR, core.editor, \$EDITOR, or \$VISUAL to edit
57 an introductory message for the patch series.
59 --subject Specify the initial "Subject:" line.
60 Only necessary if --compose is also set. If --compose
61 is not set, this will be prompted for.
63 --in-reply-to Specify the first "In-Reply-To:" header line.
64 Only used if --compose is also set. If --compose is not
65 set, this will be prompted for.
67 --chain-reply-to If set, the replies will all be to the previous
68 email sent, rather than to the first email sent.
69 Defaults to on.
71 --signed-off-cc Automatically add email addresses that appear in
72 Signed-off-by: or Cc: lines to the cc: list. Defaults to on.
74 --identity The configuration identity, a subsection to prioritise over
75 the default section.
77 --smtp-server If set, specifies the outgoing SMTP server to use.
78 Defaults to localhost. Port number can be specified here with
79 hostname:port format or by using --smtp-server-port option.
81 --smtp-server-port Specify a port on the outgoing SMTP server to connect to.
83 --smtp-user The username for SMTP-AUTH.
85 --smtp-pass The password for SMTP-AUTH.
87 --smtp-ssl If set, connects to the SMTP server using SSL.
89 --suppress-cc Suppress the specified category of auto-CC. The category
90 can be one of 'author' for the patch author, 'self' to
91 avoid copying yourself, 'sob' for Signed-off-by lines,
92 'cccmd' for the output of the cccmd, or 'all' to suppress
93 all of these.
95 --suppress-from Suppress sending emails to yourself. Defaults to off.
97 --thread Specify that the "In-Reply-To:" header should be set on all
98 emails. Defaults to on.
100 --quiet Make git-send-email less verbose. One line per email
101 should be all that is output.
103 --dry-run Do everything except actually send the emails.
105 --envelope-sender Specify the envelope sender used to send the emails.
107 --no-validate Don't perform any sanity checks on patches.
