Shell script, quotes, and variables

[Enchantment]

I'm still learning the basics of shell scripting so bear with me. I'm trying to create a simple shell script that accepts one input and writes a couple of lines out to my firewall.blocked file. Here's what I have so far.

#!/bin/sh
<stuff>
echo "# Blocked" >> $BLOCKFILE
echo "$IPCHAINS -A input -s $1 -d $MACHINENET -j DENY" >> $BLOCKFILE
<stuff>

This does create the desired information in the file, but not in the format that I want. I would like to see the following in the file
if I call it with 1.1.1.1 as the parm.

# Blocked
$IPCHAINS -A input -s 1.1.1.1 -d $MACHINENET -j DENY

The firewall script knows how to resolve the variables $IPCHAINS and $MACHINENET. I've tried various combinations of " ' and ` but I haven't found the right combo. What should my line of code look like?

Thanks

what are you typing on the command line, and what does the result in the blockfile look like? your code looks like it should work just fine.

also, i don't know if there's anything one can do in a shell script to clobber the $1,$2,etc parameters.

On the command line I'm entering "./test1 1.1.1.1"

The file then has the following lines appended to it. (I masked out the desination IP and my test1 script knows about all the variables as well.)
# Blocked
/sbin/ipchains -A input -s 1.1.1.1 -d x.x.x.x/x.x.x.x -j DENY

This is what I had hoped to have appear in the file.
# Blocked
$IPCHAINS -A input -s 1.1.1.1 -d $MACHINENET -j DENY

(We are changing to a different ISP in a few months so I'm trying to minimize the number of changes to be made on the Linux machine)

example using a diff variable so I don't gotta type out all your stuff:

echo \$PATH

will echo this:

$PATH... ie, the variable name (just escaping the $ symbol)

echo $PATH

will echo the system path... ie, what the variable value is...

Thanks Energon. That solved my problem.
