Read/write operations on the configuration file (INI/Inc. Sh) implemented by the bash script

These two bash functions were previously written to modify and read an existing ini configuration file. Of course, they are actually implemented in Linux bash shell:

For exampleConfiguration file config. ini

# config.ininame = xiwangage = 27

Run the script and change name = xiwang to name = Xiaoqiang Wang (Eric). Expected output:

xiwang@ubuntu:~/Dev/BashConfig$ ./ConfigDemo.sh config.inicontents of config.ini----------------------------------------------# config.ininame = xiwangage = 27----------------------------------------------<CFG_NAME> is Xiaoqiang Wang(Eric)contents of config.ini----------------------------------------------# config.ininame = Xiaoqiang Wang(Eric)age = 27----------------------------------------------

Instance script:

Update the shell script configuration file compatible with Inc. sh:
