I typed the "Hello, World" program in the Ubuntu text editor. The file, 'hello' was saved to the documents folder, which I verified, is there.  However, the "c" compiler, version 7.4.0-1, cannot find 'hello.' Moreover, the program 'find' cannot find it either. I would appreciate any help you can give me.

I'm trying to write a basic program in C using gedit or sublime text (which I prefer), but no matter what I do when I try to compile or run, or even while writing, I have no option to use 'stdio.h' or any similar package. Even when I start typing #include &lt;st the only word completion sublime suggests is 'struct'.  I've read dozens of threads, but all managed to fix this by installing gcc, which I've tried to reinstall multiple times, with no luck.  This is the output from gcc -v:  Using built-in specs.

Everybody knows :-) that in Windows plain text files lines are terminated with CR+LF, and in Unix&amp;Linux - with LF only. How can I quickly convert all my source code files from one format to another and back?

I found myself writing:  \vspace 1 \baselineskip   and then when it's not compiling changing without thinking to:  \vskip 1 \baselineskip   but what is the difference? Perhaps knowing this will make me write the right one from the start in the future...

I was trying to find how to pass some text to a file without overwriting what's there already using the > command and I realised I don't know what it's called. Searching for right arrow or right chevron or more than command didn't show up anything. I've always just called it pass to.

After hitting ⌘-O, how can I navigate my folders and select a file to open using only my keyboard?   In particular, how can I get the focus into the folder list? (From there I can use arrows or start typing the first letters of the desired file/folder.)  In some programs I can rely on hitting TAB 5 times, but this isn't reliable and I figure there must be a better way.

I have a couple of LaTeX files with the same problem. If I produce an error, fix it, and then try to compile a pdf, I get the following error.  )Runaway argument? {{ ! File ended while scanning use of \@newl@ablel. &lt;inserted text&gt;                 \par l.90 \begin{document}   If I then click on the console or trash my .aux file, it compiles fine. Any thoughts on what is going on and how to prevent this annoying extra step?

I compiled a small "hello world" C program on Ubuntu 10.04 32 bit machine. Then I put the executable(a.out) on Ubuntu 12.10(64 bit) VMWare virtual machine and tried to execute it(./a.out). The OS does not identify the file and says 'No such file or directory'. But when I put the same executable on a Ubuntu 12.10(64 bit) running on a 64 bit laptop, it runs fine and I get the desired output. The VM is running on IBM Blade Servers. I wanted to know why the results for a VM?

Is there a way to include an entire text file as a string in a C program at compile-time?  something like:   file.txt:  This is a little text file  main.c:  #include &lt;stdio.h&gt; int main(void) {    #blackmagicinclude("file.txt", content)    /*    equiv: char[] content = "This is\na little\ntext file";    */    printf("%s", content); }    obtaining a little program that prints on stdout "This is a little text file"  At the moment I used an hackish python script, but it's butt-ugly and limited to only one variable name, can you tell me another way to do it?

I'm going crazy...  I have a file I want to include which path is C:\Users\Matthieu\Documents\Folder withOneSpace\myFile.tex. (As you can see with the \, I'm on windows actually)  I tried the following but none works:  \input{C:/Users/Matthieu/Documents/Folder withOneSpace/myFile} \input{C:/Users/Matthieu/Documents/Folder\ withOneSpace/myFile} \input{C:/Users/Matthieu/Documents/Folder withOneSpace/myFile.tex} \input{C:/Users/Matthieu/Documents/Folder\ withOneSpace/myFile.tex}   I also tried to put the file out of the folder with a space and it works (no surprise):  \input{C:/Users/Matthieu/Documents/myFile} --&gt; Works   All I found is to put a \ before the space but it doesn't work at all. --> Please help ! :)
