• I apologize but as explained earlier The zxsuite is not a bash command and is not meant to take arguments from the standard input. hence zxsuite command will not accept commands from a file as input.
• zxsuite commands are a little faster than other bash commands in zimbra.

• The zmprov command will accept commands from a file (or stdin) as input. Create a text file ("commands.zmp" for example) with the zmprov subcommands each on a line. 
• The zxsuite is not a bash command and is not meant to take arguments from the standard input. hence zxsuite command will not accept commands from a file as input.
•  The way to achieve that is by putting the whole command in the file and executing it as a bash script.

Is it possible to run zxsuite commands in batch, like with zmprov?

For example create a file with this content

auth loginPage setFavicon domain <domain.com>"/public/<image.ext>"
auth loginPage setFavicon domain <domain.tcom> "https://domain.com/<path>/<image.ext>

and then run

zxsuite < filename
