Proper way to show which SSH commands you are running - bash

Question

I am trying to pass an array of commands to a NID device via SSH, then storing the output into a variable. I can't figure out a efficient way to display which command is running in the output.
I can get it working by looping the the array and doing 7 separate SSH sessions. Which is very slow.
n_info=$(sshpass -p "-PW-" ssh -q -o StrictHostKeyChecking=false admin#$nid_ip << EOF
${c_array[0]}
${c_array[1]}
${c_array[2]}
${c_array[3]}
${c_array[4]}
${c_array[5]}
${c_array[6]}
exit
EOF
)
echo "$i"
echo "$n_info"| sed "s/ACCEDIAN:>//g"
Expected:
[show log]
log text
log text
log text
[show config]
config text
config text
config text
Actual:
log text
log text
log text
config text
config text
config text
Commands are not static**

Simplest/cleanest solution, if it's possible, is to run the echo commands on the nid.
Assuming headers contain no shell special characters:
sshpass -p "-PW-" ssh -q -o StrictHostKeyChecking=false admin#$nid_ip << EOF
echo '[${h_array[0]}]'; ${c_array[0]}
echo '[${h_array[1]}]'; ${c_array[1]}
echo '[${h_array[2]}]'; ${c_array[2]}
echo '[${h_array[3]}]'; ${c_array[3]}
echo '[${h_array[4]}]'; ${c_array[4]}
echo '[${h_array[5]}]'; ${c_array[5]}
echo '[${h_array[6]}]'; ${c_array[6]}
exit
EOF | sed "s/ACCEDIAN:>//g"
If you are using openssh as the ssh client, it has options to use a single control connection. Something like:
REMOTE="admin#$nid"
CP_DIR="/tmp/sshctl/$$"
CP="$CP_DIR/"%L-%r#%h:%p"
mkdir -p "$CP_DIR"
sshpass -p "-PW-" \
ssh -q -nNf -o ControlMaster=yes -o ControlPath="${CP}" \
-q -o StrictHostKeyChecking=false "$REMOTE"
# !!! check you have a connection !!!
# it may work to wrap "sshpass ..." with "if ! sshpass ...; then do_error; fi"
(
for i in {0..6}; do
echo "[$h_array[$i]}]"
ssh -o ControlPath="${CP}" \
-q -o StrictHostKeyChecking=false "$REMOTE" "${c_array[$i]}"
done
ssh -O exit -o ControlPath="$CP" "$REMOTE"
) | sed "s/ACCEDIAN:>//g"
rm -r "$CP_DIR"
