psql的bash腳本

Question

這裏是我嘗試運行的shell腳本。它僅在作爲命令運行時運行，但在從腳本運行時出現錯誤。

#!/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 

以下是錯誤：

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

而不是

$(psql -U asm -d asm -t -c) echo 
"""update zr_fsinstance 
set lu_order='1' where managementaccesspointhostname = '$CE1';""" 

嘗試：

$(psql -U asm -d asm -t -c "UPDATE zr_fsinstance set lu_order='1' 
    where managementaccesspointhostname = ${CE1};") 

或者（如果您喜歡）：

`psql -U asm -d asm -t -c "UPDATE zr_fsinstance set lu_order='1' 
where managementaccesspointhostname = ${CE1};"`
