the else is nested between the if and fi

something like that:

if (a=b)
xxxxxx
xxxxxx
else
xxxx

sweet. I feel stupid not to think of that. thanks.

Is there a way to scan for input from user (stdin) is a bash script.

for example

echo "press y/n to answer"

scan $ans

Reads one line from stdin and stores it in ans. Hope that helps.

NOTE: Don't say $ans. $ans replaces itself with the value stored in ans. If, for example, $ans contained "foo", "read $ans" would be equivalent to saying "read foo" which would read one line from standard input and store it in the environment variable foo.

Here's a bash program I wrote that you might like..

It has examples of both things you want to do..

I wrote that program to take a list of MACs that have no associated IP I steal using Kismet from a wifi network with MAC filtering on and use that list to change my wifi mac address to "steal" and IP. It's useful :-P
