Ultimate Guide to Check the Softwares Version

Netsparker Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

by | | Sysadmin

Wondering how to check the version of Nodejs, Ansible, Ubuntu, PostgreSQL, Windows, Python and many more?

I believe there should be a standard way to check the version of all the software, but unfortunately, it doesn’t exist. I can guess it’s not possible as not every software is made from the same programming language.

Sometimes, it is a struggling moment to find out the software version installed on your server or PC.

Here I try to consolidate some of the popular ones, hope you will like it!

Nginx

Checking Nginx version is easy.

nginx -v

Ex:

[email protected]:~# nginx -v
nginx version: nginx/1.14.0 (EasyEngine)
[email protected]:~#

Apache HTTP

Similar to Nginx, you can use -v with httpd file.

[[email protected] ~]# /usr/sbin/httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built:   Nov  5 2018 01:47:09
[[email protected] ~]#

Change the httpd path to the actual where it is installed.

PHP

Similar to Nginx.

php -v

Ex:

[email protected]:~# /usr/bin/php -v
PHP 7.2.15-0ubuntu0.18.04.1 (cli) (built: Feb  8 2019 14:54:22) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.2.15-0ubuntu0.18.04.1, Copyright (c) 1999-2018, by Zend Technologies
[email protected]:~#

Nodejs

Check nodejs version with --version syntax like the following.

[[email protected] bin]# node --version
v6.16.0
[[email protected] bin]#

Python

Similar to Node.js, you can find out python version as below.

[[email protected] bin]# python --version
Python 2.7.5
[[email protected] bin]#

Anaconda

Using Anaconda platform for Python? Here is how you can find the Anaconda version. Assuming, you are running on UNIX-based OS.

[email protected]:~# conda list anaconda
# packages in environment at /root/anaconda3:
#
# Name                    Version                   Build  Channel
anaconda                  2018.12                  py37_0  
anaconda-client           1.7.2                    py37_0  
anaconda-navigator        1.9.6                    py37_0  
anaconda-project          0.8.2                    py37_0  
[email protected]:~#

If you just need to know the anaconda version then add $ at the end.

[email protected]:~# conda list anaconda$
# packages in environment at /root/anaconda3:
#
# Name                    Version                   Build  Channel
anaconda                  2018.12                  py37_0  
[email protected]:~#

PowerShell

On PowerShell command prompt, execute the following command to get the version.

PS C:\Windows\system32> $PSVersionTable

Name                           Value
----                           -----

MySQL/MariaDB

Slightly different than PHP. To check the MySQL or MariaDB version, you have to use the following command.

mysql -V

Ex:

[email protected]:~# mysql -V

To check the PostgreSQL client version

psql -V

And, to check the PostgreSQL server version

pg_config --version

Redis Server

By using -v syntax.

redis-server -v

Java

Execute java with -version and you will have the version details.

[[email protected] bin]# java -version
openjdk version "1.8.0_191"
OpenJDK Runtime Environment (build 1.8.0_191-b12)
OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)
[[email protected] bin]#

If you are trying to find java version the server and its not in the path, then you may have to give the absolute path to execute java.

Ubuntu

To check the ubuntu version, use the below command.

lsb_release -a

Ex:

[email protected]:~$ lsb_release -a
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.1 LTS

[email protected]:~$

CentOS/RHEL

Wondering on which version of RHEL you are logged in? You can check the version by cat /etc/redhat-release

This PC

  • Go to start and search for This PC
  • Right click on This PC and Properties
  • It will open the system window where you will find the OS version and other information like type of computer/server, model, processor, RAM, manufacturer, etc.

Tomcat

Apache Tomcat has a dedicated version file which you will find under bin folder. You just need to execute that to find out the Tomcat version.

[[email protected] bin]# ./version.sh 
Using CATALINA_BASE:   /root/apache-tomcat-9.0.16
Using CATALINA_HOME:   /root/apache-tomcat-9.0.16
Using CATALINA_TMPDIR: /root/apache-tomcat-9.0.16/temp
Using JRE_HOME:        /
Using CLASSPATH:       /root/apache-tomcat-9.0.16/bin/bootstrap.jar:/root/apache-tomcat-9.0.16/bin/tomcat-juli.jar

WildFly

You can either check using command or through the management console.
