hidden-files

I came across a link that shows how to hide number of files inside an image file: http://lifehacker.com/282119/hide-files-inside-of-jpeg-images more discussion on detection here: http://ask.metafilter.com/119943/How-to-detect-RARsEXEs-hidden-in-JPGs I'm trying to find out what is a good way to programmatically detect whether an image file has other files hidden inside it? Should I try unzipping the file to see if other files come out of it? I'm not bound programmatically but something that works well on the JVM would be great. Update One Approach: Would something like this work (suggested by

tar on a directory mydir will archive hidden files and hidden subdirectories, but tar from within mydir with a * wildcard will not. Is this a longstanding and known inconsistency or bug? Edit (additional information): tar from within mydir with a wildcard will not "see" nor archive hidden files and hidden subdirectories in the immediate directory. However, in the non-hidden subdirectories of mydir hidden files and hidden subdirectories will be archived. With wildcard it will not work. You have to specify . (current directory) if you mean full directory including hidden files. You can do tar

I want to create SSL certificate for my domain via the webroot directory ".well-known/acme-challenge" for verification. I'm using shared hosting and I don't have access to apache configuration files, so I can only use .htaccess file. Problem is that I can't access files in this folder from browser using address " my.domain /.well-known/acme-challenge/ filename ".

So I want to know, if there's any rule, which I could use in .htaccess file to gain access to hidden directories from browser. If you need more informations

Using MATLAB, I need to extract an array of "valid" files from a directory. By valid, I mean they must not be a directory and they must not be a hidden file. Filtering out directories is easy enough because the structure that dir returns has a field called isDir. However I also need to filter out hidden files that MacOSX or Windows might put in the directory. What is the easiest cross-platform way to do this? I don't really understand how hidden files work. Jonas You can combine DIR and FILEATTRIB to check for hidden files. folder = uigetdir('please choose directory'); fileList = dir(folder);

I am searching through a Git repository and would like to include the .git folder. grep does not include this folder if I run grep -r search * What would be a grep command to include this folder? Please refer to the solution at the end of this post as a better alternative to what you're doing. You can explicitly include hidden files (a directory is also a file). grep -r search * .* The * will match all files except hidden ones and .* will match only hidden files. However this will fail if there are either no non-hidden files or no hidden files in a given directory. You could of course
