The application can be anything, a program, a script, etc.

If you think the answer is "find" command with *log as the query, it is correct but not the most optimal one, as it will search in all of the file systems for matches and that will take a lot of time.

Checking in /var/log can be proposed as another solution but remember, we cannot be certain that the application logs are stored in "/var/log", it can be inside any other directory as well.

Application specific paths can be checked as well, but we might not know the path in every case where the app files are copied/ deployed.

Just using "ps -ef | grep java" can do the work in a few cases if the process details contain the path to log file, but it wouldn't work in all cases again.

We can use the "Isof -l /file/path" but remember the initial question, we don't know the log/ app path.

Thus the best way is to use the LSOF command together with the PS command.

Above will return all of the files that are opened by the process which will include the log for sure.

We can then use TAIL, HEAD, VIM, CAT, etc to navigate through the file.
