The command you provided, "jhat ${dump_file-bin}", seems to be a Unix/Linux command that involves using the jhat tool.

jhat: The "jhat" command is a tool provided by the Java Development Kit (JDK) for troubleshooting and analyzing Java heap dumps. It is used to run a web server that allows you to browse and analyze the heap dump in a graphical interface.
${dump_file-bin}: Here, "${dump_file-bin}" denotes a placeholder or variable. It suggests that the command is expecting a variable named "dump_file" to be passed as an argument. The "-bin" suffix could be part of the variable value or simply a naming convention.

So, in summary, the command "jhat ${dump_file-bin}" is used to run the jhat tool with the heap dump file specified by the "dump_file" variable. The exact behavior and output would depend on the value of the variable and the presence of the required heap dump file.
