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.
This explanation was created by an AI. In most cases those are correct. But please always be careful and
never run a command you are not sure if it is safe.
