Bash script for psql - psql

Question

Here is the shell script I am trying to run. It works when just run as a command but getting errors when run from the script.
#!/bin/bash
# sets CE IP addresses to act as LUS on pgsql
#Checks that user is logged in as root
if [ $(id -u) = "0" ]; then
#Asks user for IP of CE1
echo -n "Enter the IP address of your first CE's management module > "
read CE1
$(psql -U asm -d asm -t -c) echo """update zr_fsinstance set lu_order='1' where managementaccesspointhostname = '$CE1';"""
echo "LUS seetings have been completed"
else
#Warns user of error and sends status to stderr
echo "You must be logged in as root to run this script." >&2
exit 1
fi
Here is the error:
psql: option requires an argument -- 'c'
Try "psql --help" for more information.
update zr_fsinstance set lu_order='1' where managementaccesspointhostname = '10.134.39.139';

Answer 1

Instead of
$(psql -U asm -d asm -t -c) echo
"""update zr_fsinstance
set lu_order='1' where managementaccesspointhostname = '$CE1';"""
Try:
$(psql -U asm -d asm -t -c "UPDATE zr_fsinstance set lu_order='1'
where managementaccesspointhostname = ${CE1};")
OR (if you prefer):
`psql -U asm -d asm -t -c "UPDATE zr_fsinstance set lu_order='1'
where managementaccesspointhostname = ${CE1};"`
