Programming :: Bash - Read Content Of File To Variable And Use This Variable In For Loop ?
Aug 21, 2009I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.
For example:
Code:
Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).
Programming :: Make A New Variable With The String From The Old Variable Btut Without Any Plus Sign?
Apr 7, 2010my 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

Programming :: Change Or Add Paths For The Compiler To Look In When Using The "<>" Operator?
May 12, 2010My compiler won't find <new>. Since it's such a basic function, I'm a bit confused. Is <new> supposed to be in a file of its own? Where do I find it? And if it turns out to be missing on my computer, where can I find a <new> one? Or do you see anything else that I do wrong?
After some trying out, it seems I can't find stuff like iostream or any other basic stuff either. The compiler is prolly looking for them at the wrong place. Does anyone know how I change or add paths for the compiler to look in when using the "<>" operator?

View 1 Replies View RelatedUbuntu :: E: Could Not Perform Immediate Configuration On 'util-linux'
May 15, 2010I ran into this problem myself, and I've seen that others have had the same problem when updating from Karmic to Lucid via apt-get. There is a bug in apt for Lucid, and it has been noted on one of the Ubuntu lists
This is a simple how-to and a work-around to the upgrading with apt-get:
1) Update your sources.list file to replace all instances of 'karmic" to 'lucid' : $ sudo sed -i 's/karmic/lucid/g' /etc/apt/sources.list
2) Run apt-get update: $ sudo apt-get update
3) Run a regular upgrade; $ sudo apt-get upgrade -y
Here is where the problem comes in. Apt is looking for the util-linux package, which is part of upstart-job, but someone apparenlty forgot to write the code to tell apt-about this (whoops!)
So, you now need to install upstart-job by itself. By skipping this step you will get the error message when you try to run step 5: "E: Could not perform immediate configuration on 'util-linux'.Please see man 5 apt"
4) $ sudo apt-get install upstart-job
5) Now you can run apt-get dist-upgrade: $ sudo apt-get dist-upgrade -y

May 19, 2010I've found that my skype stopped working with recent -current updates ( around beta ... ). It was looking for a libuuid.so.1 library - on checking I found the 64-bit version but no 32-bit version - quite strange as this has been working fine since my original slackware64 13.0 installation. Anyhow, I got the 32-bit util-linux package, did the 32-bit package convert thing and skype is now working:
1. convertpkg-compat32 -i util-linux-ng-2.17.2-i486-1.txz
2. un-archive
3. copy the libuuid lib to /lib and soft-link in /usr/lib
I didn't install the whole compat package as this is not really necessary I think.
Debian :: Util To Generate Thumbnails / Contact Sheet From Video?
Apr 1, 2011I'm looking for suggestions for a command line utility than can generate a contact sheet (e.g. jpg etc) from a video? I'm mainly interested in starting from FLV files, but i guess the solution will probably work for other formats with appropriate codecs etc. So, for example, if i have a 30 minute video, every 2 minutes through it i'd like it to generate a thumbnail and then put 15 of these in a 5 x 3 grid in a single jpg. On Windows,Media Player Classic Homecinem will do this through its ave Thumbnails command.
Ideally i'd like to do this from the command line/script in a debian server environment, rather than a desktop GUI. It doesn't have to be a single command, if a chain of steps could do it.
Ubuntu Servers :: Hdd Hiccups - Wait At 99%, Iostat Util At 99% For NO Reason?
Jan 28, 2010I use this machine as a samba server with one small IDE hdd for system and one large SATA hdd (1.5TB) hooked via 4xSATA PCI card. The machine has 1.5GB RAM, and is also to run 2 ktorrent clients inside two Xvncs.The problem is, that even when ktorrent is doing nothing I observe A LOT of hdd activity to the point where movies or even mp3s stored on this server played via samba on a windows machine "stutter". E.g. smplayer will repeat 5 second piece a few times before moving on to the next piece... and it goes on for a good 10 minutes, once it starts.Even browsing directories is slow to the point where it takes 5-20 seconds to show the content in Total Commander (equivalent of Midnight Commander for windows).I am not sure how I can track what is really happening. Why would ktorrent clients create a massive I/O when there's virtually no traffic to/from them? (I have total of 1kB/s down and 10kB/s up while taking the masurements below).Or is there something wrong with the hdd? I had to send back the first one I got, it had plenty of bad sectors (this one does not though, as far as I can tell no data loss occured, just performance sucks).Here's some diagnostic data, please let me know if there's anything else I should check.

Jul 18, 20111st. I lost my usb drives. Im using Puppy Studio(Lucid, Full HDD install, latest ver) on a Toshiba Satellite 2805-S201... My 1st Linux treasure... Anyway... I was recording audio thru audacity. Shutdown. L8r started and inserted a Flash drive and the icon never showed even though I used it hours prior with no issues. The drives are working fine meaning I can access the data on other devices. Now the newb... I cant find the USB info anywhere. i followed System-Status & Configure-Hardware info-Devices-USB devices and theres nothing there. The optical drive & sda1 are registered but the flash drives are not. Does it sound like my 2 USB ports are dead? My mouse & keyboard dont register either!
2nd. B4 today reboot was the only command I knew (so sad...) but I learned dmesg and tried that and dmesg reads
Ext2-fs (sda1): error: ext2_Lookup: deleted inode referenced 83359
Basically I now want to move my music but I have no working usb ports. And Its been frustrating trying to figure out what the dmesg means when today is the 1st time I opened a terminal!

What I would like to know is how to build the content (the home-main.php)? Do it dynamically based on a link something like this index.php?page=coding_b, and put in the index.php page a number of 35 if/else statements to cover all the project pages or ... static, creating every page for the projects menu when I create the menu? I check if a page 'pro-co-a.php' exists, if not I create it based on some template and do the query to get the content from db or? How to organize the pages, if using static page?
