How to run a jar file in a linux commandline

How to set the classpath to the current directory and also run the jar file named load.jar present in the current directory by providing the argument as load=2 from a linux command line.

I did try to run the jar as follows but its executing classes from some other directory.

java -cp ./load.jar:$CLASSPATH load.Start load=2

In my case I had to utilize an additional flag- console to get it up and running:

java -jar jarfilename.jar -console

The console flag was needed to run the file in shell and do instructions needed for setup like installation path and accept terms and conditions.

copy your file in linux Java directory

cp yourfile.jar /java/bin

open the directory

cd /java/bin

and execute your file

./java -jar yourfile.jar

or all in one try this command:

/java/bin/java -jar jarfilefolder/jarfile.jar

Under linux there's a package called binfmt-support that allows you to run directly your jar without typing java -jar:

sudo apt-get install binfmt-support
chmod u+x my-jar.jar
./my-jar.jar # there you go!

Running a from class inside your JAR file load.jar is possible via

java -jar load.jar

When doing so, you have to define the application entry point. Usually this is done by providing a manifest file that contains the Main-Class tag. For documentation and examples have a look at this page. The argument load=2 can be supplied like in a normal Java applications:
