Where command_t is executed and its exit status tested. If it's zero, the commands enclosed between the do and done are executed. Then command_t is executed again and its exit status tested. If it's zero, the commands enclosed between the do and done are once again executed. This process continues until command_t returns a nonzero exit status. At that point, execution of the loop is terminated. Execution then proceeds with the command that follows the done.
Why not substitute 1 with true and drop the parenthesis, braces, and brackets

smd-loop
smd-loop(1) Sync Mail Dir (smd) documentation smd-loop(1)NAME
smd-loop - iterates smd-pull and smd-push
SYNOPSIS
smd-loop [-vt]
DESCRIPTION
smd-loop runs smd-push and smd-pull at regular intervals as defined by the user in the ~/.smd/loop configuration file. On errors that are
reported to be transient, it retries a second time before failing.
The configuration file is line-oriented. Each line is composed of three space separated fields: pull-frequency, push-frequency and end-
point-name. Frequencies are expressed in minutes, while endpoint name is a valid name for smd-pull(1) and smd-push(1). Lines beginning with
# are considered as comments. The following example calls the command smd-pull default every 3 minutes, and smd-push default every 10.
Example:
# pull-frequency push-frequency endpoint-name
3 10 default
OPTIONS -v Increase program verbosity (printed on stderr)
-t Just create a template configuration file if none
