Send gmail from the commandline
Basic options: to/sender/cc/bcc/subject. The following sends an basic message:
sendgmail.py --sender "..." --to "..." --cc "..." --bcc "..." --subject "..." --message "message:
In the above sender is a single email address, while to, cc and bcc are comma-separated lists of email addresses.
Message options:
sendgmail.py --message "..."
sendgmail.py --mfile message.txt
cat message.txt | sendgmail.py --mfile -
cat message.txt | sendgmail.py [without --mfile or --message specfied]
If the first option is used with the others, they are processed in the above order. Note that you can send an empty message using --message "".
You can add another file as a signature:
sendgmail.py --sfile signature.txt
This is helpful if you are using the configuration below, and you want sendgmail.py to handle the signature. However, it has the same effect as adding extra text via --mfile.
Attachments:
sendgmail.py --attach file.pdf [file.pdf]
Saved configuration: Can be included (1) on the command line
sendgmail.py --configuration config.json
or (2) be in a file config.json in the current directory.
If those are not the case, but --sender ABC@DEF is specified then (3)
$HOME/.config/sendgmail/ABC@DEF/config.json
is checked. Finally, (4)
$HOME/.config/sendgmail/config.json
is checked.
The config file looks like
{
"to": "...",
"from": "...",
"cc": "...",
"bcc": "...",
"subject": "...",
"attach": [ "...pdf", "...jpg", ...],
"message": "some text",
"mfile": "message.txt",
"sfile": "signature.txt",
"credentials": "credentials.json",
"token": "token.pickle"
}
Note that all credentials and token files are relative to the config file, unless you use ./ or '/', i.e.,
{
"credentials": "./credentials.json",
"token": "./token.pickle"
}
or
{
"credentials": "/home/user/somewhere/credentials.json",
"token": "/home/user/somewhere/token.pickle"
}
Most (1) either be included on the command line:
python3 sendgmail.py --credentials credentials.json --token token.pickle
or (2) must be in files credentials.json/token.pickle in the current directory or (3) must be specified in the config file (see above).
If none of these, then if --sender ABC@DEF, then (4)
$HOME/.config/sendgmail/ABC@DEF/credentials.json
$HOME/.config/sendgmail/ABC@DEF/token.pickle
is checked and finally (5)
$HOME/.config/sendgmail/credentials.json
$HOME/.config/sendgmail/token.pickle
is checked. I.e., command line takes highest precedence, $HOME/.config/sendgmail takes lowest precedence.
