shell scripting

Dear All,

Can anyone help me to access the value of var$i in shell scripting.

With regards,
Keerti

In *NIX, shell variables or environment variables are prefixed with $ and followed by a name. So $i is a variable, as is $var. var$i is confusing to me in the context of your post.

If you want to see the value held by a variable, use "echo". E.g. :-

Code:

echo $i

echo $var

echo $PATH

echo $HOME

perhaps you mean

Code:

eval value=\${var${i}}

echo ${value}

Code:

var=var${i}

echo ${!var}
