Include command output to json - json

Question

Trying to send a weekly overview of the backup size from a bash script which does a curl to send a message.
echo $(curl -s \
-X POST \
--user "aasdfasdfbc:4adgadfgsdfg" \
https://api.mailjet.com/v3/send \
-H "Content-Type: application/json" \
-d '{
"FromEmail":"noreply#bashdrsh.li",
"FromName":"Backup Notification",
"Recipients": [
{
"Email":"back.upper#bashdrsh.li"
}
],
"Subject":"['"$host"'] Backup overview",
"Text-part":"Backup on '"$host"' weekly overview\n\n '"$(find /tmp/backup/2017-07-12/ -maxdepth 1 -type f -exec ls -hls {} \; | awk '{ printf "%-40s %30s\n", $10, $6 }')"'\n"
}')
But the find command always returns with this response
find: paths must precede expression: globals-only.7z
Usage: find [-H] [-L] [-P] [-Olevel] [-D help|tree|search|stat|rates|opt|exec|time] [path...] [expression]
{
"FromEmail":"noreply#bashdrsh.li",
"FromName":"Backup Notification",
"Recipients": [
{
"Email":"back.upper#bashdrsh.li"
}
],
"Subject":"[MYLOCAL] Backup overview",
"Text-part":"Backup on MYLOCAL weekly overview\n\n \n"
}
Running the find command on command line it returns everything as expected
# find /tmp/backup/2017-07-12/ -name '*.7z' -exec ls -hls {} \; | awk '{ printf "%-40s %30s\n", $10, $6 }'
/tmp/backup/2017-07-12/globals-only.7z 7.3K
/tmp/backup/2017-07-12/auth.7z 759
How can I include a nice formatted table into the message?

Answer 1

You're not using the same find expression in curl invocation and later on command line. Also, no need for ls & awk.
Try replacing your complete command substitution with:
find /tmp/backup/2017-07-12/ -name '*.7z' -printf "%-40P %30s\n"
For readability, you can store that into a variable, and use like:
output=$(find /tmp/backup/2017-07-12/ -name '*.7z' -printf "%-40P %30s\n")
echo $(curl -s \
-X POST \
--user "aasdfasdfbc:4adgadfgsdfg" \
https://api.mailjet.com/v3/send \
-H "Content-Type: application/json" \
-d '{
"FromEmail":"noreply#bashdrsh.li",
"FromName":"Backup Notification",
"Recipients": [
{
"Email":"back.upper#bashdrsh.li"
}
],
"Subject":"['"$host"'] Backup overview",
"Text-part":"Backup on '"$host"' weekly overview\n\n '"$output"'\n"
}')
