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.

csp_scp_keep_mode
csp_helper(1) USER COMMANDS csp_helper(1)
NAME
csp_helper - A collection of caspar helper scripts
SYNOPSIS
csp_install dir (directory) file (file)
csp_mkdircp dir (directory) file (file)
csp_scp_keep_mode h ([user@]host) dir (directory) file (file)
csp_sucp h ([user@]host) dir (directory) file (file)
DESCRIPTION
The scripts csp_install, csp_mkdircp, csp_scp_keep_mode and csp_sucp are helpers for caspar(7). These scripts typically are not invoked
directly, but via a Makefile which uses caspar. See the notes on csp_PUSH in caspar(7) for information on how to link csp_install,
csp_scp_keep_mode and csp_sucp to caspar.
install DESCRIPTION
csp_install creates the required directory (if needed) and installs the file, preserving timestamps. It uses install(1).
install EXAMPLES
csp_INSTALL_OPTIONS='--owner=www-data --group=www-data'
csp_INSTALL_MODE=ugo=r
csp_install /srv/www index.html
csp_INSTALL_MODE=u=rwx,go= csp_install /usr/local/sbin mkpasswd
install ENVIRONMENT
csp_install honors csp_INSTALL_OPTIONS and csp_INSTALL_MODE (default is u=rw,go=r).
mkdircp DESCRIPTION
csp_mkdircp calls mkdir(1) and cp(1).
scp_keep_mode DESCRIPTION
csp_scp_keep_mode uses ssh to copy a file to a remote host, keeping its file permission mode. The trick used is a combination of mktemp(1)
and mv(1). Useful if you'd like to be sure a file gets installed e.g. group writable, without fiddling with permission bits on the remote
host.
scp_keep_mode EXAMPLE
chmod g+w rc
csp_scp_keep_mode root@gandalf /etc/uruk rc
scp_keep_mode ENVIRONMENT
csp_scp_keep_mode honors csp_SSH ("ssh" by default).
sucp DESCRIPTION
csp_sucp calls cat(1) from within sudo(1) from within ssh(1). This allows one to copy files to accounts on hosts one can only reach by call-
ing sudo on the ssh-reachable remote host.
Typically, one wants to install a root-owned file, but one does not want to allow access to the root-account directly from ssh. Typically
sudo is used as an extra line of defense.
sucp EXAMPLES
Some examples:
csp_sucp rms@bilbo /etc fstab
csp_sucp monty-python commit/ trailer.txt
sucp BUGS
If NOPASSWD is not set in the sudoers(5) file, and one's timestamp is expired, csp_sucp will forward the sudo password prompt. The given
password will be echoed on the console!
