Editing Search for string in json files

Search for string in multiple JSON files

== Approaches ==
=== Approach 1: Content of JSON file contains the keyword(s) ===
* Input: (1) Specify the folder path (2) Specify the keyword(s)
* Output: file name list
* Command: {{kbd | key=<nowiki>find *.json | xargs grep -E "詐騙|詐欺" -sl</nowiki>}} to find json files which its content contains the string {{kbd | key=<nowiki>詐騙</nowiki>}} or {{kbd | key=<nowiki>詐欺</nowiki>}}.


=== Approach 2: The specified index/column contains the keyword(s) ===
* Requirement: Install [https://stedolan.github.io/jq/ jq]
* Input: (1) Specify the folder path (2) Specify the keyword(s) (3) Specify the index/column of JSON
* Output: file name and the value of specified index/column
* Command 1: {{kbd | key=<nowiki>find . -name '*.json' | xargs -I {} jq '{"file": input_filename, "MYCOLUMN": ..|.MYCOLUMN?}' {} | jq -c 'select(.MYCOLUMN | contains("詐騙"))'</nowiki>}} to find json files which content of column {{kbd | key=MYCOLUMN}} contains the string {{kbd | key=<nowiki>詐騙</nowiki>}}<ref>[https://medium.com/@marvinirwin/bash-snippet-find-every-file-containing-a-non-empty-array-value-with-find-xargs-and-jq-cc456d3705e4 bash snippet: Find every file containing a non empty array value with find, xargs, and jq | by Marvin Irwin | Medium]</ref>.
* Command 2 for multiple keywords using boolean OR operator: {{kbd | key=<nowiki>find . -name '*.json' | xargs -I {} jq '{"file": input_filename, "MYCOLUMN": ..|.MYCOLUMN?}' {} | jq -c 'select(.MYCOLUMN | contains("詐騙") or contains("詐欺"))'</nowiki>}} to find json files which content of column {{kbd | key=MYCOLUMN}} contains the string {{kbd | key=<nowiki>詐騙</nowiki>}} or {{kbd | key=<nowiki>詐欺</nowiki>}}.
* Command 3 for multiple keywords using boolean AND operator: {{kbd | key=<nowiki>find . -name '*.json' | xargs -I {} jq '{"file": input_filename, "MYCOLUMN": ..|.MYCOLUMN?}' {} | jq -c 'select(.MYCOLUMN | contains("詐騙") and contains("詐欺"))'</nowiki>}} to find json files which content of column {{kbd | key=MYCOLUMN}} contains the string {{kbd | key=<nowiki>詐騙</nowiki>}} and {{kbd | key=<nowiki>詐欺</nowiki>}}.
