How to read each cell of a column in csv and take each as input for jq in bash - bash

Question

I am trying to read each cell of CSV and treat it as an input for the JQ command. Below is my code:
line.csv
| Line |
|:---- |
| 11 |
| 22 |
| 33 |
Code to read CSV:
while read line
do
echo "Line is : $line"
done < line.csv
Output:
Line is 11
Line is 22
jq Command
jq 'select(.scan.line == '"$1"') | .scan.line,"|", .scan.service,"|", .scan.comment_1,"|", .scan.comment_2,"|", .scan.comment_3' linescan.json | xargs
I have a linescan.json which have values for line, service, comment_1, comment_2, comment_3
I want to read each value of csv and treat the input in jq query where $1 is mentioned.

Answer 1

Given the input files and desired output:
line.csv
22,Test1
3389,Test2
10,Test3
linescan.json
{
"scan": {
"line": 3389,
"service": "Linetest",
"comment_1": "Line is tested1",
"comment_2": "Line is tested2",
"comment_3": "Line is tested3"
}
}
desired output:
Test2 | 3389 | Linetest | Line is tested1 | Line is tested2 | Line is tested3
Here's a solution with jq:
This is a shot in the dark, as you didn't specify what your output should look like:
jq -sr --rawfile lineArr line.csv '
(
$lineArr | split("\n") | del(.[-1]) | .[] | split(",")
) as [$lineNum,$prefix] |
.[] | select(.scan.line == ($lineNum | tonumber)) |
[
$prefix,
.scan.line,
.scan.service,
.scan.comment_1,
.scan.comment_2,
.scan.comment_3
] |
join(" | ")
' linescan.json
Update: with jq 1.5:
#!/bin/bash
jq -sr --slurpfile lineArr <(jq -R 'split(",")' line.csv) '
($lineArr | .[]) as [$lineNum,$prefix] |
.[] | select(.scan.line == ($lineNum | tonumber)) |
[
$prefix,
(.scan.line | tostring),
.scan.service,
.scan.comment_1,
.scan.comment_2,
.scan.comment_3
] |
join(" | ")
' linescan.json
