Programming :: Can't Use Dollar Sign In String
Jul 17, 2011
i have a bunch of ubnt nanostations M series (wireless access points/routers)... they use airOS (a fork of openwrt). it runs a custom firmware that i made using provided sdk. and the lighttpd uses php/fi 2.0.1.... this is (of course) used to serve the web configuration.the problem: i need to use the ($) in a string but i couldn't. what i need to do is download some file from the internet using wget and have the pid of wget back to keep track of the process, then parse the output to the page.

I'm trying to setup a linux computer to connect to my works wirless. It uses a WPA2 password with a dollar sign in it. I can't input it into wpa_passphrase because it thinks dollar sign means some command.
How do I tell it that the dollar sign is part of the password?

I am trying to use Ubuntu terminal to execute unix commands. However, the dollar sign that usually appears in shell terminal is missing. Please see the attached screenshot image showing the terminal without the dollar sign. I cannot run any unix commands like cd, ls-l. Please advise how I could fix this problem.

I have a String that I would like to sign using a given RSA Private key. I thought this would be relatively easy but I have not been able to find out how to do it, unless I'm looking to far into a simple problem. Do i have to put the string into a file, and sign the file, or can i just sign the string/message?

my script has a variable which comes in the form +00.00 +0.00 -00.00 or -0.00 (the numbers can be any in that form) for any that have a + symbol I need to remove the +, but if it has a - symbol it needs to stay.
i need to make a new variable with the string from the old variable btut without any plus sign. I have tried a lot of different ways with no success, each thing I tried either left the + or removed the entire string. I think this should work but doesn't
foo=+12.40
bar=${foo#+}

I've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.
[Code]....
One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?
Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.

So if I'm given a location of a file like:
How can I just take the type of the file at the end? I know I can use strrchr() for a period to get the pointer to the period just before file type. Is there a build in string function that will just take the rest of the string from a certain point on forward in the string? I know it wouldn't be much work to make it myself, but I figured I would find out if it already existed before doing it.

I'm having problems completing my school exercises with awk.
Heres the desired outcome:
Code:
./my_awk 2
ACG GAG ATT AGG AGG ATC CCA CCA
CAC AGG ACG GAG ATT AGG AGG ATC
So it generates data in group of threes, 8 groups per row and prints it. My problem is that I can't seem to get awk to append stuff to string so I could print it nicely to screen. It just prints empty lines per the parameter given to it.
Heres my code so far:
Code:
#!/bin/sh
awk -v rows=$1 '
