I want to use the parameters that we define in the Jenkins job as arguments to the shell commands in the same job.
I have created a parameterized build with the following parameters:
high.version: 234 low.version: 220 I want to use these variables as arguments for the build's shell script:
/bin/bash /hai/mycode/scripts/run_script.sh high.version How do I these parameters in the same job?

Using arguments Inside the script, we can use the $ symbol followed by the integer to access the arguments passed. For example, $1 , $2 , and so on. The $0 will contain the script name.
How do you access parameters set in the "This build is parameterized" section of a "Workflow" Jenkins job? Create a WORKFLOW job. Enable "This build is parameterized". Add a STRING PARAMETER foo with default value bar text .
Using Jenkins built-in "Execute shell" you can run commands using unix shell. If you need to run a job cross platform you cannot use the two standard executors provided by Jenkins. You need a "build step" that can be executed both in Windows and in Unix.
What really helped me was Hudson: How to pass parameters to shell script
Solution: the variables are UPPERCASE even you define them in lowercase!

Jenkins will create environment variables with the parameters' names.
The caveat here is that Jenkins will also do that for parameters that do not represent valid variable names -- those are difficult to access in bash. This is the case in your example, as bash variable names must not contain the . character.
The easiest solution is that you
high_version and low_version (which are valid bash variable names)Example:
/bin/bash /hai/mycode/scripts/run_script.sh "$high_version" If you cannot rename parameters to represent valid bash variable names (e.g., for usability reasons: Jenkins presents variable names to end users in the Web form for starting a build): you can still access such parameters by grepping for the parameter name in the output of the env command.
