parallel:tldr:2f298
This command is a combination of two separate commands, piped together with the "|" symbol.
The first part of the command, "${args}", is a placeholder representing a list of arguments that will be passed as input to the second command.
The "|" symbol is known as the pipe operator in the command line. It allows the output of the first command to be used as the input of the second command.
The second part of the command, "parallel -X ${command}", is using the GNU Parallel tool. This tool is used to execute commands in parallel. It takes input from stdin and applies the specified command to each input item in parallel.
In this case, the -X flag is used to specify that the input items will be parsed by treating whitespace as the item separator. The actual command to be executed for each input item is represented by the placeholder "${command}". This placeholder should be replaced with the actual command you want to run.
To summarize, this command takes a list of arguments represented by "${args}", passes them as input to the parallel command, and executes the specified "${command}" in parallel for each input item.
