Syntax Question

Bella

I'm still a newbie at this.

I have a file called setup.sh

ipaddr=curl getipaddr.net -s | head -n 1

secret=''blah"

radiusip='YOURRADIUSIPHERE'

echo "$radiusip $secret" >> /etc/ppp/options.pptpd

What I want it to do is add

11.55.22.66 blah to /etc/ppp/options.pptpd

But what ends up happening is it adds

$radiusip $secret

instead of the actual value of those variables.

Can someone help me.

I can tell you that

 ipaddr=curl getipaddr.net -s | head -n 1 

should be

 ipaddr=`curl getipaddr.net -s | head -n 1` 

The ticks puts the results of that command into the variable ipaddr.

#!/bin/bash
secret="blah"
radiusip='YOURRADIUSiphere'

echo "$secret $radiusip" >> testFile

definitely works.

Be aware that in markdown syntax the back tick will be displayed as pre tag.

ipaddr=`curl getipaddr.net -s | head -n 1`

displays as

ipaddr=curl getipaddr.net -s | head -n 1

And to be honest I couldn't find any problem in the given script.
