Using Grep to create multiple variables in a loop per line - BASH

Question

I'm trying to take a multiline file in the above format and make MySQL insert statement from it. End result aim is something similar to outputting: -

insert into ansible_db (ip, version) values ("$ip", "$version") 

per line for each of the following data examples (this is the input file, I want the IP address and the result of the msg segment - ie 4.0.3): -

ok: [192.168.0.214] => {s    "msg": "4.0.3"s}
ok: [192.168.0.210] => {s    "msg": "4.0.8"s}
ok: [192.168.0.208] => {s    "msg": "fdsajkghjfdka"s}
ok: [192.168.0.216] => {s    "msg": "Potatoes""""s}

The following greps get the IP's and message out appropriately: -

$ip=grep -oE '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' 
$version= grep -oP '(?<=\"\: \").*(?=\"s})' #format of the message will vary going forward. 

I want to put it in a loop, but I'm struggling. Any advice appreciated.

Answer 1

In this case, while-loop is not required. If your file is having the consistent structure like you provided in the question following command should print the required lines.

awk -v FS='[][]|"' '{print "insert into ansible_db (ip, version) values ( \""$2 "\" , \""$6"\" )" }' yourInputFile

Note that above command will display the result in std out, if you want to execute then you can use |bash in the end of the command like:

awk -v FS='[][]|"' '{print "insert into ansible_db (ip, version) values ( "$2 " , "$6" )" }' yourInputFile |bash

Note, MySql VALUES syntax requires complex string arguments to be enclosed with quotes.
To obtain valid MySql insert statements use the following approach:

awk '{ gsub(/[\[\]]/,"",$2); sub("\"+s}","\"",$6); 
       print "insert into ansible_db (ip, version) values (\""$2"\", "$6");" }' file

The output:

insert into ansible_db (ip, version) values ("192.168.0.214", "4.0.3");
insert into ansible_db (ip, version) values ("192.168.0.210", "4.0.8");
insert into ansible_db (ip, version) values ("192.168.0.208", "fdsajkghjfdka");
insert into ansible_db (ip, version) values ("192.168.0.216", "Potatoes");
