jello:tldr:5cc94
This command is used to read the contents of a JSON file and pass it as input to the "jello" command with a specific flag "-s".
Here's the breakdown of the command:
-
"cat" is a command in Unix-like operating systems that is used to concatenate and display the contents of files. In this case, it is used to read the contents of a file.
-
"${file-json}" is a placeholder that represents the name or path of the JSON file. The "$" and "{" are used to denote variable substitution in Unix-like systems. So, this part of the command expects a variable named "file-json" to be defined elsewhere, containing the file name or path.
-
"|" is a pipe symbol used in Unix-like systems to redirect the output of one command as the input to another command. In this case, it is used to pass the output of the "cat" command to the "jello" command.
-
"jello" is another command or program that is being executed. It might be some custom command or an application installed on the system.
-
"-s" is a flag or option specific to the "jello" command. The purpose of this flag is specific to the "jello" command and would require further context or documentation to understand its functionality.
In summary, the command reads the contents of a JSON file specified by the variable "${file-json}" and passes it as input to the "jello" command along with the "-s" flag.
