Check your double quotes, some have one too many.
And just as an addendum, from 'shellcheck', see attached image...
Hi wisecracker,
Thank you for catching the mismatched double-quotes. I was trying to change "$var"/string to "$var/string" and didn't complete the job in a couple of lines.
I'm sorry that shellcheck doesn't like stand-alone redirections. They are part of the shell command language and there is no need to combine them with another command when used as they are used in the script being discussed in this thread.
Note also that the commands:
produces the same results in the script being discussed in this thread but runs slower and just like:
will give a zero exit status even when > "${LOG_DIR}/message" failed if > "${LOG_DIR}/wtmp" succeeded.
Of course, the discussion would be different if other pipelines that send output to standard output without redirecting that output were to be included in the script after these redirections; but that isn't the case here in cleanup2. Nonetheless, I should have stated this assumption in the example I provided.

AC(8) System Manager's Manual AC(8)NAME
ac - login accounting
SYNOPSIS
/usr/sbin/ac [ -w wtmp ] [ -p ] [ -d ] [ people ] ...
DESCRIPTION
Ac produces a printout giving connect time for each user who has logged in during the life of the current wtmp file. A total is also pro-
duced. -w is used to specify an alternate wtmp file. -p prints individual totals; without this option, only totals are printed. -d
causes a printout for each midnight to midnight period. Any people will limit the printout to only the specified login names. If no wtmp
file is given, /usr/adm/wtmp is used.
The accounting file /usr/adm/wtmp is maintained by init and login. Neither of these programs creates the file, so if it does not exist no
connect-time accounting is done. To start accounting, it should be created with length 0. On the other hand if the file is left undis-
turbed it will grow without bound, so periodically any information desired should be collected and the file truncated.

/usr/adm/wtmp
