jq:tldr:b446f

jq: Execute a specific script.
$ ${cat filename-json} | jq --from-file ${path-to-script-jq}
try on your machine

This command combines the use of two tools: cat and jq, used in a Bash-like shell environment.

  1. ${cat filename-json}: This is command substitution using ${} syntax. It executes the cat command with filename-json as an argument. The purpose of cat is to display the contents of a file (filename-json in this case) in the terminal.

  2. |: This is a pipe symbol that connects the output of the previous command to the input of the next command. It allows the output of cat to be passed as input for the next command (jq).

  3. jq --from-file ${path-to-script-jq}: Here, jq is a lightweight command-line JSON processor. It is used to process JSON data. In this command, the --from-file option is used to specify a script file (${path-to-script-jq}) containing operations to be performed on the JSON input.

Overall, this command takes the contents of the filename-json file, pipes it to jq, and uses a script file (${path-to-script-jq}) to process and manipulate the JSON data.
