I have a file of 2GB size in hex form. This is a log file from the server which I converted to hex as the file got corrupted.Can anyone tell how to convert this hex file to ASCII?
To start off I would like to acknowledge that I am not a very good C programmer and pretty much everything I know has been self taught through mostly trial and error. So forgive me if there is an obvious answer to my question, or if I don't immediately grasp the concepts involved in the possible solution.
Basically, I'm writing an application which will be creating log file entries rather rapidly (potentially hundreds per minute), and I would like each new line to appear at the top of the log file, rather than the end. Opening a text file in append mode is easy enough, but I can't seem to find any obvious way to do the opposite.
I have been looking online and it seems that there exists no standard way to do this, and I have only been able to find a few mentions of how somebody might achieve it. The most common method seems to be using two files and copying the data back and forth between them. This seems like it would be insanely I/O intensive with the number of lines I'm likely to be generating. If this is the best method to use, I will give it a shot; though I am not 100% clear on how to implement it, I am also open to any other ideas as to how to accomplish this, and I don't have to worry about portability since the program already uses Linux-only libraries. So calling out to sed or something is not necessarily out of the question (though I imagine performance would also be an issue there).
I need to be able to convert HTML email messages saved as text files (.eml or .msg) to PDF documents, one PDF per email, retaining formatting and images.
Are there any Linux tools that will allow me to do this from the command line (so it can be scripted)?
I get an error when trying to convert a .avi file to a .iso file using Devede. If I leave the "Create a menu with the titles" option as is I get no error. But I don't want any slideshow so I untick that option. I then get this error when the process is almost done; Failed to create the DVD tree Maybe you ran out of disk space I do have enough disk space so that can't be the problem. Anyone know what to do about this problem?
I'm looking for a tool that can directly convert mp3 file to a swf file. Tried ffmprg - 'ffmpeg -i master.mp3 -ar 22050 -ab 32 -f swf -y -vn new.swf', output is as follows:
I found a way to perform this task using ffmpeg to convert the mp3 file to a wav file, and converting the wav into a swf file using swftools (wav2swf), although this is not a good option because the output swf file size is very big - for a 12mb input 320kbps stereo mp3 file, the swf file is 25mb. Also downloaded a free direct mp3 to swf conversion software, which had an output swf file - with the same 12mb mp3 file - of ~400kb.
The requirements I have from the tool are:
1. Can be ran from the shell.
2. Direct conversion, or an indirect one that will produce a small output swf file.
In a project I'm working on with a few other people, I got the task of writing an assembler. The last thing I do is convert the commands into a binary representation, and jam it into a file. Now one of my teammates said he'd like to be able to "reference" the code within another program. He said he'd be able to do this if the file I output is a Linux object file. I'm thinking it'd also work as an executable. Anyway, he said he'd like to be able to grab the file and reference the binary by address. I'm still fuzzy on this, and if you're confused with what I said here, please tell me so I can ask him for better details.Anyway, I'm aware that gcc can compile files to ".o", but that's only for C/C++, and my file is just binary. I'm also aware of "ld", but I haven't seen any use of it to help me. I'm happy to hear suggestions as to what I can do. If anything, I think I'll implement a few functions to grab the bits and hand them to him in an array or something.
Anyone know of any programs to convert a postscript file to a gerber file? LinkCAD can do it, but, it is very expensive and I can't get the demo to run.
trying to convert a avi file with subtitles into a iso file ready for burning on to a disc, I am using DeVeDe to convert the file but I keep getting the error SPUMUX when trying to convert. I have no idea on what to do with this, is it because I am trying to convert to ISO? should I just try to convert to MPEG instead would that stop the error?
i'm trying to convert a html file into a text file when i simply run "html2text <filename>" the output displayed is the way we want but when i redirect the same using "-o" or ">>" the file is having extra characters in it. i even tried -ascii,but no much use.
I am trying to convert my batch file into a .sh file and i think i have it perfect but it just will not work, so obviously not perfect. This is the code for my batch file.

This works perfectly on my own computer without any problems. I want to host this on my Linux VPS (CentOS 5) and need it to be converted into run.sh. This is the code for my run.sh.
Recently I tried to convert a .flv file to an mpeg file using ffmpeg. Although I changed directory to the directory in which the.flv file resided FFMPEG said the file did not exist. However when I gave the "ls" command the file was present. Where is my mistake?
i working with a simulator tool that i need to pass to it a file in .BIN format, basically i need to convert from a tex plain file to BIN file How can i do that? there is some command(s) that allow me do
I want to convert an .iso video file to an .avi file. Google searches suggested using dvd:rip. Dvd::rip didn't work for me because I am using a netbook that doesn't have a DVD drive. I'm using eeebuntu on an Asus eeePC 1000HE.
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:
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:
