40git-send-email [options] <file | directory>...
41Options:
42 --from Specify the "From:" line of the email to be sent.
43
44 --to Specify the primary "To:" line of the email.
45
46 --cc Specify an initial "Cc:" list for the entire series
47 of emails.
48
49 --bcc Specify a list of email addresses that should be Bcc:
50 on all the emails.
51
52 --compose Use \$EDITOR to edit an introductory message for the
53 patch series.
54
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.
58
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.
62
63 --chain-reply-to If set, the replies will all be to the previous
64 email sent, rather than to the first email sent.
65 Defaults to on.
66
67 --no-signed-off-cc Suppress the automatic addition of email addresses
abec100c
BF

71 --smtp-server If set, specifies the outgoing SMTP server to use.
72 Defaults to localhost.
73
74 --suppress-from Suppress sending emails to yourself if your address
75 appears in a From: line.
76
77 --quiet Make git-send-email less verbose. One line per email

79
238cc635
RJ
80 --dry-run Do everything except actually send the emails.
81
f073a592
