Examples of linux shell reads a configuration file

Configuration file as follows:

#Created by JInto - www.guh-software.de
#Tue Aug 28 22:20:17 GMT+08:00 2018
aas_amountuser_switch=1
aas_fleet_switch=1
aas_usertokenproct_switch=1
aas_usertokenproct_num=5
aas_devtokenproct_switch=1
......

 

Read the script as follows:

# /bin/bash

configuration_file_path="/opt/some_path/common-conf"

current_value=`grep 'aas_amountuser_switch' ${configuration_file_path}/uiConfig.properties | cut -d = -f2  | sed 's/\r//'`
echo "$current_value"

if [ "$current_value" = "0" ]; then
  sed -i 's/aas_amountuser_switch=0/aas_amountuser_switch=1/' ${configuration_file_path}/uiConfig.properties
  echo "modify uiConfig.properties.aas_amountuser_switch success"
else
  echo "modify uiConfig.properties.aas_amountuser_switch error"
  exit
be

 

note:

　　At the end of the file in linux there are characters '\ r', need to pay attention to remove line breaks

　　This small point is not easy to find, so do not see the problem in the script, they can open the debug shell, it is easy to locate out as follows:

　　　　sh -x test.sh
