Question

This is my case:

Even though the command I run is not so relevant, I’ll still include it.

user@machine:$ java -classpath /home/user/mysql.jar:/home/user/jericho-html.jar:/home/user JavaFile

I have introduced an error in the java code, so the command gives the output:

[ERROR] null
Exception in thread "main" java.lang.Exception
[ERROR] input:
null
  at JavaFile.main(JavaFile.java:111)

What I want to achieve is to write this output to a file, and then to send the file to my e-mail address. I’ve sorted the e-mail stuff out, but I can’t figure out how to write this output to a file.

I’ve tried adding >> filename.txt to the end of the command, but that does nothing. And I can’t locate the java log files on the system, if they even exist.

Answer 1

You have to redirect stderr to your file. Use &>> instead >> for redirection. That way you will redirect all output (stderr and stdout).
