I'm used to holding the left Alt and entering the ASCII character whenever I'm using an unknown keyboard configuration and want to type a special character. For example, Alt-092 makes a backslash (). That's on Windows. Is there a way to do this in Ubuntu ?
Note : I also want to be able to use this in console mode. That means I don't want a solution involving a software with a GUI.
Is there a known tool to convert a file consisting of 2 byte Hex into ascii?
Note: - Maintain file offset listing in bytes code...
To encrypt the text, we take the word "python" and make it at least the same size as "welcome home" by repeating it as follows:
w e l c o m e h o m e
p y t h o n p y t h o n
Then, we convert each letter into its numerical ASCII value as follows:
w e l c o m e h o m e = 119 101 108 099 111 109 101 032 104 111 109 101
[Code].....
And, finally, we convert the numbers back into their corresponding ASCII character:
To know the function on checking whether a character is ascii or unicode character. From the following [uRL]. The function IsTextUnicode is related to Windows VC++ library. I would like to know the library/function which provides such facility.

I know I can grab the ones with what I want to kill (which are the ones with question marks) with:

what I need to know is how can I loop through the results of the second one and kill them by id (the second column).
I have a csv file that has around 3 million rows.

I am loading variables for cXtXdXsX disk names into a script, and at present I have only accounted for there being 3 characters from c to t. I need to change it to a variable recognition so that it can count any number of charcters such as c1t , c10t , or c100t.
I can then take that information and use it with the following string to strip off the lead characters so as to make the 3 in $substr either a variable or redirect to multiple occurrences of raw based on the count returned.
sub raw {
$substr = substr ($_, 3);
$raw1 = substr ($substr, 0, -4);
$raw = lc($raw1);
}
how to count from the c to the t inclusive so I get 3, 4, 5, etc ...
I get heaps of errors from Okular saying that /tmp/kde-luke/* cannot be opened. I think it is doing this because I downloaded files from Firefox and opened them then closed firefox before closing the pdf files. I have tried uninstalling a purging Okular deleting the applications stuff in my home directory but it is still obsessed with these files. The only way I have been able to stop these annoying pop ups is by having the application uninstalled or running a starup script that will create these files on boot.
View 2 Replies View RelatedI'm trying to get my head around compiling programs, and need some things clarified. Can anyone confirm or deny my understanding so far:
1) Program is written in high level language, such as C. File(s) of the program are the 'source code'.
2) Program is then 'compiled' to turn it into low-level code that is both hardware - i.e. Intel/AMD/ARM processor specific, and also Linux distribution specific. This resulting files are called the binaries.
3) I can go from source code to installed and usable program by doing these steps:
./configure
make
make install

View 5 Replies View RelatedHow can I use extended ascii characters, like ALT + 2 + 0 + 0 for instance? I'm using some of those characters for my passwords for online accounts made under MS Windows and it seams I'm unable to use them in Slackware 13. For instance: if I type ALT+2+0+0 in Pidgin there is no character displayed and if I type in the Terminal the same thing, it will replace my shell prompter (sasser@HOSTA:~$) with (arg: 200):

I have an application where the client is written in Visual Studio (C#), run on PCs, and the server end has traditionally been SCO. We're now migrating to Linux. I can, for example, input "Test This" in a text box on the client, and when the server end is SCO, it is able to 'accept' the character sent to it from the client. When I try this same example on Linux, that character (hex D1) does not 'make it' from the client to the server.
The problem is not on the client, and I have verified that the telnet connection is in fact passing these extended characters, but they are not recognized properly by the Linux server.In researching this, I've played with setting the LANG environmental variable from LANG=en_US.UTF-8 to several of the other possible values found in /usr/lib/locale, for a european locale (the end user is actually in Spain), and these 'euro' characters are still not handled properly in my application.Would anyone be able to point me to any specific env variable settings, and/or anything else that would resolve this issue?
for example
else {

View 4 Replies View RelatedI have created a small script to compile a network weathermap using the cacti RRD files. The script reads the *.conf files and outputs an html and a png file. When I manually run the script it works normally.
I have edited my crontab with the crontab -e command to run this script every minute
The problem is script itself works when I manually call it but when it is run using crontab it doesn't do anything. The cron.log shows that the script IS being run every minute with no errors but the files (html and png) do not get written. What am I doing wrong and how do troubleshoot this?

I have a problem with Plymouth. It works pretty well on low res, but on higher resolution some strange video artefacts appear - see attachments.
I use ATI proprietary drivers, if it has something to do with it.
The resolution is set in /etc/default/grub like this:
Code:
GRUB_GFXMODE=1024x768
GRUB_GFXPAYLOAD_LINUX=1024x768x32
edit: reducing colour depth doesn't help /end edit
I don't know whether it has anything to do with the current problem, but Plymouth used not to appear at all until I followed these instructions (or actually I took them from another thread but I can't find it at the moment and these are the same).
I don't know whether it's possible to take them during booting so I've taken these photos with a mobile and retouched in gimp to remove reflections (more or less), and since I'm no pro photographer nor photoshop/gimp master they look as they look. They should do to demonstrate the problem, though.
I was messing around with the alternate character panel app and made a custom character set. I then wanted to put it on a new panel and created a new panel. I moved the character set to that panel, and then started to mess around with the panel settings (auto hide, show hide buttons, and expand, to be specific.) So far so good, until I moved the panel from the right side of the screen to the top. I already had a panel here, and it seemed not to like hiding a panel when there was already one on the top.
When the new panel hid itself, all my panels stopped responding (any clicks on them did nothing) and my processor started going at 100%. I tried a reboot and the only thing that changed is that now I can't even see my panels. I'm guessing I need to change the settings back manually through the prompt, but I don't know how to do that. I am using 10.04 and have not upgraded gnome since upgrading to 10.04.
This is weird, and I never noticed before, but now I have an application that is borking on weird things like when /etc/hosts is of one file format or another, and I don't even know the difference between the two (google doesn't tell much either). on CentOS 5.5/5.6 x86_64: a which on the following is an interesting tell:
vi = /bin/vi
vim = /usr/bin/vim
both are actually vim version 7.0.237 but sum differently, and although they are both actually separate executables in the stock installs of CentOS I've been building, on most distros, and older versions of CentOS it seems, vi is usually just a symlink to vim - but again, not in these fresh installs it seems. When I create a file with the 'vi' above, it defaults (usually) to "ASCII text" (but not always) When I create a file with the 'vim' above, it defaults to "ASCII English text" (and causes a particular application I'm working with to bork and barf). It seems the OS is installed by default yielding both file types too, as evidenced by the following:

I'm using a Norwegian keyboard where these are placed such that I have to stretch my fingers a bit too long for whats comfortable. To make it easier I though I'd try to make alt+[some key] be one of these characters. Is there a way that I can bind, say alt+� (Norwegian letter) to '{' system wide?Btw, is such thing called binding, mapping or something else? I'm getting a bit confused by the terms...
