spaces

This may be a total beginner's question, but I have yet to find an answer that works for me. Currently, I'm writing a program for a class that takes in a user's input (which can be one or more numbers separated by spaces), then determines whether the number is prime, perfect, or neither. If the number is perfect, then it will display the divisors. Thus far, I've already written the code for the prime, perfect, and listing the divisors. I'm stuck on the input portion of my program. I don't know how to get the input that's separated by spaces to go through my loops one at a time. This is my

This question already has answers here : here-document gives 'unexpected end of file' error (5 answers) For personal development and projects I work on, we use four spaces instead of tabs. However, I need to use a heredoc, and I can't do so without breaking the indention flow. The only working way to do this I can think of would be this: usage() { cat << ' EOF' | sed -e 's/^ //'; Hello, this is a cool program. This should get unindented. This code should stay indented: something() { echo It works, yo!; } That's all. EOF } Is there a better way to do this? Let me know if this belongs on the

I have a number of files in a folder, and I want to replace every space character in all file names with underscores. How can I achieve this? neesh This should do it: for file in *; do mv "$file" `echo $file | tr ' ' '_'` ; done I prefer to use the command 'rename', which takes Perl-style regexes: rename "s/ /_/g" * You can do a dry run with the -n flag: rename -n "s/ /_/g" * Use sh... for i in *' '*; do mv "$i" `echo $i | sed -e 's/ /_/g'`; done If you want to try this out before pulling the trigger just change mv to echo mv . What if you want to apply the replace task recursively ? How would

I've trouble setting up Vim (7.1.xxx) for editing Python files (*.py). Indenting seems to be broken (optimal 4 spaces). I've followed some tutorials I found via Google. Still no effect :/ Please help. I use this on my macbook: " configure expanding of tabs for various file types au BufRead,BufNewFile *.py set expandtab au BufRead,BufNewFile *.c set noexpandtab au BufRead,BufNewFile *.h set noexpandtab au BufRead,BufNewFile Makefile* set noexpandtab " -------------------------------------------------------------------------------- " configure editor with tabs and nice stuff... " ---------------

Currently I have this code which replaces any double space with a <br /> . It works as expected: <tr class="' . ($counter++ % 2 ? "odd" : "even") . '"> <td>Garments:</td> <td>' . str_replace(' ', '<br /><br />', trim($result['garment_type'] ) ) . '</td> </tr> However I want to do another str_replace() on the same line to replace any single spaces with a pipe character | . I tried duplicating the code but that just creates another TD for me. Any help would be appreciated. The order of the array does matter otherwise you will get <br|/> instead of <br /> so try: str_replace(array(' ','||'),

If I for example have my url looking like index.php?category=IT%20&%20Soft. Then i try to print "$_GET[category]" i only get "IT" and not "IT & Soft". What is wrong here? It's frustrating me. The problem is not the spaces, but the ampersand. Use %26 instead, like this: index.php?category=IT%20%26%20Soft The ampersand indicates that you are beginning another field (like category=IT&subcategory=somethingelse ). You can see a list of reserved characters on Wikipedia . Spaces and ampersands (&) aren't valid and need to be encoded for use in parameter values. Run your arguments through 'urlencode'
