How to shutdown jshell at the end of the script?
(3 answers)
Closed 5 years ago.
I recently upgraded to java9 and I am using the Jshell option which java provides.
I find it intuitive but I am not able to close the Jshell window, can someone suggest some command for the same.
you can simply type /exit to exit the jshell console.
you can find more info about jshell here
https://docs.oracle.com/javase/9/tools/jshell.htm#JSWOR-GUID-C337353B-074A-431C-993F-60C226163F00
Use /exit to exit the jshell.
For all the available options use /help.

How can I debug a Bash script? [closed]
(12 answers)
Closed 2 years ago.
I'm not sure I address this problem correctly, but I've search and search over the net and found nothing, yet.
I'm writing a bash script and I want to see what the script is really doing when being executed, like a log of all the commands, one by one, what are executed - this way, I'll be able to see why my script is falling.
Note : I've post similar question in the past, someone told me I run my bash script with sh -xe script.sh but it doesn't give me enough information to debug properly.
Please advise. Thanks!
Adding set -x at the beginning of the script displays, in the terminal, all the commands sent by the script as the terminal received it. It was exactly what I needed and it working perfectly.

How execute bash script line by line?

I work with git-bash in windows. I have found a bash script that I would like to modify on GitHub. I cloned it and opened it in my pycharm editor. There is a plugin https://www.plugin-dev.com/project/bashsupport/#installation which I've added, but from the documentation this does things like syntax highlighting. Is there a way to step through the code line by line, set breakpoints etc. I don't have much shell scripting experience and stepping through the code might speed up my learning .
I usually debug using -x flag (short for xtrace or execution trace) is useful to add execution information Debugging Bash scripts).
You can use it by executing:
bash -x your-script.sh
or adding adding into your script:
set -x

It's indicating that the command you've typed is not complete, and it's still waiting for the rest of it.

I have already tried 'reset' and removing my .bashrc file.
Try "chsh -s /bin/sh" if you want to use sh. To see what your available shells are, "cat /etc/shells". You can also see what your current shell is by "echo $0" and simply "exec /bin/sh" will change shell for your session (not perm).
Changing default shell - /etc/passwd - for your unix account:
username:x:1000:1000:,,,:/home/username:/bin/bash
