So I have a script that does a greater than or less than with a variable. My problem is that when I checked the script from the command line I was getting this error..
I am not really familiar with shell scripting. I am trying to get this script to work with conky so that it will do the functions and give the output. I got this script online, so it might be done all wrong...

For a test. Just after setting the value of $lq , try displaying the value:
echo "lq = $lq"
Assuming that the value is definitely an integer number, then lose the double quotes in all your integer comparisons.
I dont want to sound stupid with this question, but where do you want me to set it in the code that I posted?
I assume you want the Signal Level?
My iwconfig has values separated by "=".
root@bt > iwconfig wlan0|grep 'Link Quality='
Link Quality=56/70 Signal level=-54 dBm
So, the following statement gives me the Signal Strength
iwconfig wlan0|grep 'Link Quality=' | grep --max-count=1 -o '\=\([0-9]\+\)' | grep --max-count=1 -o '\([0-9]\+\)'
60
If the above does not work, paste the output of iwconfig wlan0
Try this also...
root@bt > iwconfig wlan0 | sed -n 's/.*Signal level[:=]-\([0-9]*\).*/\1/gp'
56
Usage in your script would be
lp=$( iwconfig wlan0 | sed -n 's/.*Signal level[:=]-\([0-9]*\).*/\1/gp' )
--ahamed
So this was the output:
iwconfig eth1 | sed -n 's/.*Signal level[:=]-\([0-9]*\).*/\1/gp'
gave me nothing back
M1330:~$ sudo iwconfig eth1 | sed -n 's/.*Signal level[:=]-\([0-9]*\).*/\1/gp'
46 Gave me a signal back
It only works when I use sudo. And my wireless uses eth1. I need to find a way to get past the sudo iwconfig eth1 thing.....any ideas? As long as I use sudo I can get a signal # back. If I don't use sudo, then nothing... The only way that I was able to get the bitrate and ssid is by doing sudo conky. If I do just conky, then those two things won't show up. It's like their hidden behind root priveleges for some reason...
Yes, iwconfig/ifconfig etc are admin commands. Looks like sudo is configured for the user you are trying with. So there shouldn't be a problem.
--ahamed
So how could I get rid of the sudo way with the conky scripts?
I am not very familiar with conky. I just installed and tried invoking with a normal user and it required root privileges.
My question is : If sudo is configured for you, why don't you want to use it?
If prefixing sudo is a problem for you, try creating an alias kind in your script and use that... Something like this...
CONKY="/usr/bin/sudo /usr/bin/conky"
...
...
$CONKY inputargs
--ahamed
My main problem now is that I still cant get the wlanscript.sh to work with my conky. I feel like I have all the paths right, but I cannot get the picture for the signal to show up at all...Here is the code:
