jstack: Print stack traces from Java core dump.
$ jstack ${-usr-bin-java} ${file-core}
try on your machine
The command you provided appears to be using a combination of variables and arguments specific to the jstack utility, which is a command-line tool used for generating Java stack traces of a running Java process.
Let's break down the command:
${-usr-bin-java}: This appears to be a variable that represents the path to the Java executable (e.g.,/usr/bin/java). The exact value of this variable would depend on the system configuration.${file-core}: This is another variable that likely represents the path to a core file, which is a binary file that contains a snapshot of a process's memory. The exact value of this variable would also depend on the file's location.
Overall, the command seems to be using jstack to generate a stack trace for a Java process using the supplied Java executable and core file. However, without knowing the specific context or purpose of this command, it is difficult to provide a more detailed explanation or determine if any other arguments or options are required.
