[Config Save] Error happens when saving a file with quotation marks in its filename

[rayxhuangEC]

When running the command sudo config save "\"atlas_config_1x100G\[40G\]\(4\)\"" -y, an error happened.

admin@DUT7:/etc/sonic$ sudo config save "\"atlas_config_1x100G\[40G\]\(4\)\"" -y
Running command: /usr/local/bin/sonic-cfggen -d --print-data > "atlas_config_1x100G\[40G\]\(4\)"
Traceback (most recent call last):
File "/usr/local/lib/python3.9/dist-packages/config/main.py", line 152, in read_json_file
with open(fileName) as f:
FileNotFoundError: [Errno 2] No such file or directory: '"atlas_config_1x100G\\[40G\\]\\(4\\)"'

What I did

The command "config save" invoke the command "/usr/local/bin/sonic-cfggen -d --print-data" and use the redirection mechanism to gererate a config file. However, in this proccedure, some of the characters will be stripped by the linux shell, e.g. ", ', and \, that it will save a file doesn't same with the original input filename. And after gernerating the config file, it will open the file and arrange the data. The fail happened when it tried to open a file didn't exist. That is because the filename of the file it tried to open doesn't match the file it created.

Fix the command "config save" that it can match the filename it created and it tried to open.

How I did it

Strip the filename by 'echo' command that the filename can conform the linux shell command rule.

How to verify it

Run the command sudo config save "\"atlas_config_1x100G\[40G\]\(4\)\"" -y

Previous command output (if the output of a command-line utility has changed)
