xe:tldr:2a534

This command is a shell command with placeholders denoted by curly braces {}. The placeholders are meant to be replaced with actual values before executing the command.

Here is the breakdown of the command:

• ${arguments_source}: This placeholder represents the source of the arguments that will be provided to the command.
• |: This pipe symbol is used to redirect the output of the command on the left to the input of the command on the right.
• xe: This is the name of the executable or command that will be executed.
• ${command}: This placeholder represents the specific command or action to be performed by the xe executable.
• {}: This placeholder represents the position where the actual arguments will be inserted. The arguments are sourced from ${arguments_source}.
• ${optional_extra_arguments}: This placeholder represents any additional arguments that may be required for the specified ${command}.

To execute this command, you need to replace the placeholders with appropriate values. For example, if ${arguments_source} is replaced with input.txt, ${command} is replaced with count, and ${optional_extra_arguments} is replaced with -l, the command will be something like:

input.txt | xe count {} -l

This will execute the xe command, specifically the count action, using the arguments sourced from input.txt and any optional extra arguments specified by -l.
