echo the variable ... 1

[hokky]

Hi guys,

Here's my example

one=start
two=$one

$$ echo $two
start  --> I want the result is $one, how do I do that?

Hi guys, this is simple question, but I couldn't get it out...

I want to echo $two and the result is $one, anybody can tell me how do I do that ?

Thanks guys

sorry PHV,

one more question

what about if I wanna get it back without typing it again.

I've tried this, but doesnt work :

test_function(){
    name=`$two | sed 's/\'//g'`
    echo "$name"

}

Sorry, I don't understand what you want to do.

Sorry,

I'll give you closer example

test_function(){
    echo $1
    name=`echo $1 | sed "s/\'//g"`
    $name
}

test_function '$ENVIRONMENT_VARIABLE/path/of/script/scriptname.ksh'

I want to echo the script after that run it.

use the eval builtin to have the shell re-expand the variable:

test_function(){
    [b]eval [/b]echo $1
    name=`[b]eval [/b]echo $1 | sed "s/\'//g"`
    $name
}

HTH,
