cut:tldr:31da9
This command is a combination of two separate commands being run in a pipeline.
The first part of the command, ${command}, represents a placeholder that should be replaced with the actual command you want to run. It could be any valid command that produces output.
The output of ${command} is then piped (|) to the second part of the command, which utilizes the cut command.
The cut command is used to extract specific fields or columns from a given input. In this case, the --delimiter="${,}" option specifies that the delimiter used in the input is a comma surrounded by double quotes, which means comma is treated as the delimiter.
The --${fields}=${1} part of the command is another placeholder. The ${fields} represents the fields or columns you want to extract, and ${1} represents a placeholder for the value you want to provide for the fields option. You'll have to replace ${fields} and ${1} with the actual values you want to use.
To summarize, this command takes the output of ${command}, treats commas surrounded by double quotes as the delimiter, and extracts the specified fields/columns based on the values provided.
