The following is the test command from the tutorial:
./logstash -e 'input { stdin { } } output { stdout {} }'
The following is the error.
WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults

As for the error message part that says:
Path "/usr/share/logstash/data" must be a writable directory. It is not writable.
The directory is owned and writable by logstash.
Can anyone suggest any solutions?

Try adding a stdout output with debug set to true. You should be able to see the entire event object and errors / warnings in your logstash --log or stdout. Hope that helps! debug => true doesn't work any more (tested on v2.
Inside the bin folder, run the elasticsearch. bat file in case of windows or you can do the same using the command prompt and through the terminal. In UNIX, run the Logstash file. We need to specify the input source, output source and optional filters.
The most basic thing to check is the status of the Logstash status: sudo service logstash status.
You have to start logstash in the sudo mode. That is
host@host:~$ sudo su
root@host:/home/host# cd /usr/share/logstash
root@host:/usr/share/logstash# ./bin/logstash -e 'input { stdin { } } output { stdout {} }'

the exception message tells you that logstash can't find configure property, so you should add a flag in the command to tell logstash the configure property.and another exception is the logstash can't write something to the /usr/share/logstash/data , you should use 'sudo' to start this command, or you can add the write permission of /usr/share/logstash/data to your account.
logstash version:5.5.2
os version:ubuntu 16.04
the command of starting logstash as flow:
sudo bin/logstash -e 'input { stdin { } } output { stdout {} }' --path.settings=/etc/logstash
ps:I install logstash by apt install the document of install logstash
