Use double quotes around variables to avoid trimming of spaces. Look at the below example carefully. You'll understand what shell is doing to those extra whitespaces.
Code:
[root@host user]# x="hello world"
[root@host user]# echo $x
hello world
[root@host user]# echo "$x"
hello world
[root@host user]# y=" earth mars"
[root@host user]# echo $y
earth mars
[root@host user]# echo "$y"
earth mars
[root@host user]# z="$x$y"
[root@host user]# echo $z
hello world earth mars
[root@host user]# echo "$z"
hello world earth mars
Nothing obvious wrong. When checking the vaue of $c, remember the quotes:
Code:
echo "$c"
For future posts, please mention what Operating System and version you are running and what Shell you are using. Also please use CODE tags to preserve space characters in your posts (which are certainly important to this post).

cout << ((j+1)%20)?... (4 Replies)
When I try to access my website's Administrator page (mysite.com/administrator), I'm redirected to (mysite.comadministrator), as if the slash was removed from the URL
The funny thing is that I can access it if I enter 2 slashes (mysite.com//administrator)
Any ideas of what might be causing it? (4 Replies)
