MySQL KSH variable substitution
Hi folks
Please let me know if anyone knows how to handle this.
My KSH script -> testscript.ksh

cmd=$1
ENV="devl"
echo $cmd

This is how I call the script
./testscript.ksh 'ps -ef | grep br$ENV'

How do I get this to print the below text i.e $ENV should be substituted with the value "devl".

ps -ef | grep brdevl

Regards,
Tipsy.

Unfortunately I do not have the liberty to change the parameter being passed. What I have mentioned is just an example. It can be anyother command with the $ENV.

Is there anything that I can do inside the testscript.ksh.

Try using the eval command, something like this (not tested) :
Code:
ENV="devl"
eval cmd=\"$1\"
echo $cmd

Try this:
Code:
#! /usr/bin/ksh

cmd=$1
ENV="devl"
eval cmd=\"$cmd\"
echo $cmd
exit 0
