Hi,
Open the your executable file, xxx.sh on Unix / Linux. Assign value to these three context variables 'source,dest,failure' as
--context_param source=xxx --context_param dest=xxx --context_param failure=xxx in your .sh file.
Let me know if it is OK with you.
Best regards

What's your expected result? Don't you pass value of context variable as manually? Could you give us more description about your current job and requirement.

hi,
I have perl program which call this shell script. so in perl code im passing command line argument so shell script as follows,
`sh xxx.sh \root\source \root\dest \root\fail`
and in shell script i wrote as follows,

--context_param source=${1} dest=${2} failure=${3}
now everything is working fine.
but you told in previous comment different syntax and im using different syntax. my question is "which is better way to use --context_param?? with first variable or with every context variable ??"

Hi,
They are both working for you?

--context_param source=xxx dest=xxx failure=xxx
or --context_param source=xxx --context_param dest=xxx --context_param failure=xxx

Hi,
Usually, we use context_param source=xxx --context_param dest=xxx --context_param failure=xxx parameter in .bat/.sh file.
