Shell script to add mac filters. Help?

[StoneGiraffe]

Disclaimer - I'm not even a linux newbie, I'm a straight up idiot.

I'm trying to write a script so I can more easily add mac filters via ssh. Basically I'm trying to read the old values out, add a new filter, then set.

So far I'm here and it's clearly not working.

nvram set wl0_maclist=\"`nvram get wl0_maclist` $1\"
nvram set wl0_maclist_x=\"`nvram get wl0_maclist_x`\<$1\"
nvram set wl1_maclist=\"`nvram get wl1_maclist` $1\"
nvram set wl1_maclist_x=\"`nvram get wl1_maclist_x`\<$1\"

Also, if I screw up my nvram and I don't want to commit, how do I roll back?

(Incidentally, only reason I want to do this is that the 2.4 and 5Ghz filters are separate again - I was so happy when they were merged in a previous firmware. Good things don't last forever I guess)

Ok, I updated my script and it looks like it works. My previous mistake was escaping the double quotes.

Last question though - after committing my changes to nvram how the heck do I get them to take from the shell without rebooting? I can't seem to find any doc that lets me bounce the network only.

Any hints?

My hack updated script looks like this incidentally:

#!/bin/sh
mac=`echo "$1" | sed -e 'y/abcdef/ABCDEF/'`
if ! echo "$mac" | grep -q '^\([A-F0-9]\{2\}:\)\{5\}[A-F0-9]\{2\}$'; then
    echo Not a mac address
    exit 1
fi

echo adding mac: $mac

list=`nvram get wl0_maclist`
list_x=`nvram get wl0_maclist_x`
list1=`nvram get wl1_maclist`
list1_x=`nvram get wl1_maclist_x`

if [ ! "$list" == "$list1" ]; then
    echo wl0_maclist and wl1_maclist are out of sync
    echo wl0_maclist "$list"
    echo wl1_maclist "$list1"
    exit 1
fi
if [ ! "$list_x" == "$list1_x" ]; then
    echo wl0_maclist_x and wl1_maclist_x are out of sync
    echo wl0_maclist_x "$list_x"
    echo wl1_maclist_x "$list1_x"
    exit 1
fi

list="$list $mac"
list_x="$list_x<$mac"

if ! echo "$list" | grep -q '^\(\([A-F0-9]\{2\}:\)\{5\}[A-F0-9]\{2\} \)*\(\([A-F0-9]\{2\}:\)\{5\}[A-F0-9]\{2\}\)$'; then
    echo maclist format is invalid:
    echo "$list"
    exit 1
fi
if ! echo "$list_x" | grep -q '^\([\<]\([A-F0-9]\{2\}:\)\{5\}[A-F0-9]\{2\}\)\+$'; then
    echo maclist_x format is invalid:
    echo "$list_x"
    exit 1
fi

echo maclists look ok!
nvram set wl0_maclist="$list"
nvram set wl0_maclist_x="$list_x"
nvram set wl1_maclist="$list"
nvram set wl1_maclist_x="$list_x"

Thanks!!

I figured it would be super simple but I'll be damned if I could find it on the internet.
