Error KSH Script to Execute command from specific column in file

Hi Unix Experts,Team

I have a file (say comand_file.prm), The file has a command specified in column 6 (say "./execute_script.sh"). I want to execute this command in my script.
I am writing a KSH script to achieve this. Could you please assist me with this.

awk '{print $6}' command_file.prm | sh

Thanks Yazu,
Is there any way to pass positional parameters to the command specified in column.

e.g If I need to pass ${ip_address} and ${host_name} variables to execute_script.sh, how can I get this.

Be more specific. It depends on how your script gets arguments and how your variables get values, and whether they are the same for every command or not.

Hi Yazu,
To be specific, below are two requirements.

1. In some cases I want to pass the variable values along with the command mentioned in column.

Example :- ./execute_script.sh prm1 prm2

2.If the executable mentioned in column is interactive, I want to pass inputs interactively.

Example : ./jdk-6u20-linux-i586.bin ( this will begin installation and ask for instructions during execution, like accept license agreement (yes or no) :

Please advise if this can be achieved,

How you will decide, whether the executable "defined" in column is interactive?

I don't think there is any specific way to find whether an exe is a interactive or not!!!

Hi All,

The Problem is resolved. I made it this way
echo "$line |cut -d, -f6" $PRM1 $PRM2 |sh
