linux - Determine if relative or absolute path in shell program -

March 15, 2015

As stated in the title, I need to determine that when a program is running, if the path relative Or complete:

  ./ program #relative dir / dir2 / program #relative ~ user / dir / dir2 / program #absolute / home / user / dir / dir2 / program #absolute    These are my test cases, how can I do this in a shell program?  
 Or more generally, how to check that the path in this case,  $ 0  is relative or complete?  
 
   if [["$ 0" = / *]] then: # complete path: # Relative path

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,
