Unable to execute a shell script with context variables as parameters

VChauhan1611936886 — Sat, 16 Nov 2024 00:32:06 GMT

I am trying to run a Talend job to call a unix shell script using tsystem , but I noticed that the parameters I am passing while calling the shell script is not getting passed to script.

I tried multiple ways but could not find a way to achieve this

Following is the command I used :

"sudo su - talend_user -c myscript.sh "+context.param1+" "+context.param2+" "+context.param3

Is myscript.sh a job script? Please try:

"sudo su - talend_user -c myscript.sh --context=Default --context_param varName1="+context.varName1

Hi @Shicong Hong

Will this cause a problem if context.param2 is an Integer?
How to pass multiple arguments, "sudo su - talend_user -c myscript.sh --context=Default --context_param varName1="+context.varName1+" --context_param varName2="+context.varName2

Like this? Please note the space after Name1+"

Regards,

Raghu

@Shicong Hong I tried following approach, it does not seems to be working :-

"sudo su - talend_user -c myscript.sh --context=Default --context_param param1="+context.param1+" --context_param param2="+context.param2+" --context_param param3="+context.param3+" --context_param param4="+context.param4

I also tried an alternative approach :-

"sudo su - talend_user -c myscript.sh param1="+context.param1+" param2="+context.param2+" param3="+context.param3+" param4="+context.param4

I don't see parameters getting passed to my unix shell script

The -context_param is used to pass value to context variables when executing the Talend job script out of studio, if myscript.sh is a common unix shell script, please google it on internet, eg:

I tried to search lots of options to run a script from talend and looks to me that although talend facilitates running script but does not support passing parameters to the unix shell script.
