xargs:tldr:fea5c

This command is a combination of two command-line utilities: ${arguments_source} and xargs, used to pass arguments from ${arguments_source} to ${command}.

Here's how the command works:

1. ${arguments_source}: This is a placeholder representing a command or file that outputs a list of arguments. It could be a regular command, a file with arguments separated by newlines, or a combination of commands connected with the pipe | symbol. The output may look like:

   argument1
   argument2
   argument3

2. |: This is a pipe operator used to redirect the output of ${arguments_source} to the input of the following command, xargs.

3. xargs: This is a command-line utility that reads input from standard input (piped from ${arguments_source}) and executes a command with those arguments. It takes the list of arguments and converts them into command-line arguments for ${command}.

4. -I _: This option tells xargs to replace the placeholder _ with the arguments it receives, as it executes ${command}. This is useful if ${command} requires the arguments to be placed at a specific position or in a specific format within the command.

5. ${command}: This placeholder represents the command that will be executed with the arguments passed by xargs. It can be any valid command or script that accepts the arguments provided.

6. _: This placeholder is replaced by each argument passed by xargs, and it will be positioned at the specified location within ${command}.

7. ${optional_extra_arguments}: This represents any additional arguments that you want to pass to ${command} along with the arguments provided by xargs. These could be options, flags, or additional inputs necessary for ${command} to work correctly.

In summary, this command takes a list of arguments from ${arguments_source}, pipes them to xargs, which in turn replaces the placeholder _ with each argument, and executes ${command} along with any optional extra arguments passed after _${optional_extra_arguments}.
