Programming :: Invoke The Calculator "bc" In Bash Script For Floating Point Arithmetic?
May 15, 2010My main problem right now is doing floating point arithmetic within a bash script, with variables.Right now I have a folder called "myExamples" with a script called "run_example" that runs with no issues.I plan to(1) create many folders inside [myExamples], that are named [example10] [example11]...each containing an identical copy of (run_example),(2) modify Line 172 of each copy of (run_example)...in one copy, it would be 3.00, the next copy would have 3.05, etc. (This part doesn't work!)How can use the available calculator bc code to do floating point operations?My code is below -

Jul 19, 2011I was messing around with my drive trying some different arrangements of partition to get another one inside. overall the result doesn't differ much from the original but while messing with it I done a lot of steps. I thought GParted will do the minimal number of operations but it didn't. it just traced all my operations one by one. this gave it a few days worth of work. As I don't want to loose data I can't hit cancel but I don't want to wait few days for it. Is there any way to tell it to stop after completing the current operation? It's from natty ubuntu live cd.

Nov 4, 2010I run SUSE on my machine for a year, but I'm really a newbie on Linux. In the system monitor it states:SUSE LINUX Release 11.2 Kernel Linux 2.6.31.5 -0.1 -desktop GNOME 2.28.0Last week when I rebooted my machine, I suddenly found my machine had no response to any click or typing. When the cursor move to any icons, they can be highlighted, but when I click them, no response at all. The weird thing is almost every time after I reboot the computer, it can work for a few minutes, then stop working. But if I press Ctrl+Alt+Backspace, it can be log out.
I think there must be something wrong with my GNOME, 'cause everything seems working fine when I login IceWM. recover the .config file in my home directory. But I don't have this file in my home directory.

General :: Creating Gauge With Dialog For DD Operation
Sep 18, 2010I'm writing a script based on dialog and one of it's functions is to perform a restore with dd, of which I would like to show the progress by means of the "gauge" option of the "dialog" utility. I wanted to do this by sending a USR1 signal from time to time to the dd PID, because this results into the amount of bytes already being dd-ed ont the console screen. A simple calculation based on the orginal size would result into a percentage that can be fed to the gauge function of dialog.
The challenge I'm facing now is to launch an external script (I guess with "&" to send it to the background) that sends, let's say every 5 seconds a USR1 signal to the dd PID. That would be no problem, but how do I capture the output of this "kill -USR1" to the original script? I tested this and the output is not sent to standard ouput, so it must be that it is sent to standard error. For now I don't see a way out.
General :: Find The Equivalent Command Of A Gui Operation?

Code:
cd ABC ls Now the thing is that we often don't know what that equivalent command will be. So I want to know that is there any way out to find it. What I want to do is that I shall perform any operation using mouse in the GUI mode(whatever operation it could be) and then I can see a log file to see what I actually did last(rather what the command would have been if I have worked in the text mode)...
General :: HP Pavilion Ze2805 Shuts Down After 10 Min To 7 Hrs Of Operation?
Jan 12, 2011When I first received it (used) a few weeks ago, this only happened occasionally and it took a while for a pattern to develop. The 7 hr stretch was listening to music of WCPE.org, but the next day I only could get minutes from the same site It sems to get progressively worse, yet the outside of the case, near the fan or anywhere else,doesln't get uncomfortably warm. I had another unit from the same vendor. He took that back and sent this one after a 24'hour test, but will not answer further communication. Generally I get best results if it has sat shut down overnight, but this morning even that was good for only a few minutes. It does this running XP from the hard disk or Linux from CD. Actually I would like to split the hard disk and put Linux on the second half as the default boot. But it won't run long enough to install anything now!

General :: Certification Verification Is Failed / Don't Want To Terminate Operation
Aug 6, 2010I am having an issue with HTTPS certification using curl. My curl is configured with OpenSSL. If the certification verification is failed I dont want to terminate the operation, instead I want to continue by just putting a log message. For this I have used OpenSSL SSL_CTX_set_verify() function to set my static C callback function. During HTTPS transaction, my callback is also getting called with first parameter 0 or 1 (depending upon of the certificate verification is success or failure). But even if my certification verification is failure, I want to continue. So I have hard coded to return value as 1 always from my callback function. But still I see the certification error and I don't get the page.

I have no idea what to do next. All the files in the directory are locked too. I tried to move them but this command isn't allowed either. I ran these commands under the 'root' user in SSH.
