I’m looking to develop a script where the Snapshot list is emailed to someone.
When I run doctl compute droplet snapshots $dropletid, I get the following:
ID Name Type Distribution Slug Public Min Disk
61003635 test-droplet_2020-03-22-Sun@17:34-CDT snapshot Ubuntu false 25
61004052 test-droplet_2020-03-22-Sun@17:46-CDT snapshot Ubuntu false 25
61004228 test-droplet_2020-03-22-Sun@17:52-CDT snapshot Ubuntu false 25
61005132 test-droplet_2020-03-22-Sun@18:07-CDT snapshot Ubuntu false 25
61005281 test-droplet_2020-03-22-Sun@18:11-CDT snapshot Ubuntu false 25
61007940 test-droplet_2020-03-22-Sun@19:04-CDT snapshot Ubuntu false 25
However, when I echo that to an email, with this sudo /snap/bin/doctl compute droplet snapshots $dropletid >> $email_notification, I get the following in the email:
ID Name Type Distribution Slug Public Min Disk 61003635 test-droplet_2020-03-22-Sun@17:34-CDT snapshot Ubuntu false 25 61004052 test-droplet_2020-03-22-Sun@17:46-CDT snapshot Ubuntu false 25 61004228 test-droplet_2020-03-22-Sun@17:52-CDT snapshot Ubuntu false 25 61005132 test-droplet_2020-03-22-Sun@18:07-CDT snapshot Ubuntu false 25 61005281 test-droplet_2020-03-22-Sun@18:11-CDT snapshot Ubuntu false 25 61007940 test-droplet_2020-03-22-Sun@19:04-CDT snapshot Ubuntu false 25 61008918 test-droplet_2020-03-22-Sun@19:15-CDT snapshot Ubuntu false 25
Instead of the output being on one line, I want the output to be on as many lines as being requested.
Is there something I’m missing?

Hi there @aaronmweiss,
What I usually would do in this case is save the output in a file, then with send mail you could proceed that file like this:
- sendmail email@yourdomain.com < output_file.txt
You can set your subject as the first line of the file:
Subject: Your mail subject
To save the output to a file it would look something like this:
#!/bin/bash
echo 'Subject: Your mail subject' > ~/output_file.txt
doctl compute droplet snapshots $dropletid >> ~/output_file.txt
sendmail email@yourdomain.com < ~/output_file.txt
To make things more secure rather than having a specific output file, I would recommend using the mktemp command:
#!/bin/bash
temp_output=$(mktemp /tmp/temp-output.XXXXXX)
echo 'Subject: Your mail subject' > ${temp_output}
doctl compute droplet snapshots $dropletid >> ${temp_output}
sendmail email@yourdomain.com < ${temp_output}
rm -f ${temp_output}
That way you would always have a different temp file.
Hope that this helps! Regards, Bobby
