jq:tldr:1e0d2
This command is a combination of two parts: cat filename-json
and jq '${-key1, -key2, ---}'
.
cat filename-json
is a command used to print the contents of a file named filename-json
to the standard output. The cat
command is typically used to concatenate and display the contents of files.
jq '${-key1, -key2, ---}'
is a command to process and manipulate JSON data. jq
is a lightweight and flexible command-line JSON processor. In this specific example, $
denotes the root of the JSON object, and -key1, -key2, ---
represents the keys in the object that you want to display or manipulate. The ---
won't be recognized in the actual jq
command as it's not a valid syntax.
So, when you combine these two commands with the pipe (|
) symbol, it means that the output of the cat
command will be used as input for the jq
command. This allows you to parse and extract specific data from a JSON file.
