have you checked this page? https://help.msp360.com/cloudberry-backup-mac-linux/cli/configuring-settings-via-cli

Yes, and it shows how to set them, but not how to only display them.

have you tried that command without the set option?

Thank you! Fumbled into it based on your suggestion:
./cbb option -get
CloudBerry Backup Command Line Interface started
option -get <default_option>
-get <default_option>: Possible values:
n(-notification) Notification email and user name
is(ignoressl) Ignore SSL certificates
bw(-bandwidth) Bandwidth on backup to cloud storages
bwl(-bandwidthLocal) Bandwidth on backup to local storages
mu(-memoryusage) Max allowed memory usage for multi threaded operations
tc(-threadcount) Thread count
cs(-chunksize) Default chunk size
qs(-queuesize) Queue size for Glacier restores
ps(-proxy) Proxy settings
cp(-chunkpath) Temporary chunks path, used on multipart upload
wa(-webaccess) Web Interface settings
sb(symlinkbackup) Symlinks backup mode
l(logging) Logging settings

Thanks. I wasn't sure the exact syntax, but I do now thanks to your post!
