[SOLVED] Loop

adol83 · 10-30-2012, 10:07 AM

Hello,

I would to change the default tomcat directory from /var/www[...] to /mydirectory/mywebsite

i tried this to look for the config file contains "/var/www/index.html" with
this

Code:

find / -name index.html -exec grep "/var/www/index.html" {} \;

but the output is

Code:

find: File system loop detected; "/var/named/chroot/var/named" is part of the same file system loop as "/var/named".

i tried to remove "var" directory under chroot but device is busy

What is that?

it's a chroot jail for bind. Adding a -H to the find command will stop that, but a better way is to not search the entire system in the first place.

Code:

[root@machine mydirectory]# find -H / -name index.html -exec grep "/var/www/index.html" {} \;
find: File system loop detected; "/var/named/chroot/var/named" is part of the same file system loop as "/var/named".

I understand not searching for the whole file system, though, i wish to understand what that system loop is

it's a symbolic link.

I don't understand the way you're using find cmd. You're searching for a file named "index.conf", then using a grep to filter "/var/www/index.html" from it.
In cmd that you used, find will get a list of files matching the specified pattern, and that will contain file names only, but not their full paths i.e /var/www/index.html, so using grep "<full-path-of-file> won't help you. Using grep directly is not a right way, but instead of this, you can use following cmd:

Code:

find / -name "index.html" -exec ls -la {} \; | grep <filename-you're-searching>

he's searching for text INSIDE it. It's the -name option that makes it not work, not the grep.

@Chris:- What's meaning of searching full path of file inside the file itself?
Perhaps he's trying to search the file named "index.html" in whole file system and then using grep to show that "index.html" file only (but in a incorrect way).

@adol83:- Can you clear the situation, what you're searching for, a file named "index.html" and then a word "/var/www/index.html" inside it OR searching for the "index.html" file only?

It worked out a little more as soon i took off the "-name" option. But it stucked after a couple of hour and i broke with CTRL+C

Anyway that was a research of some content inside the "index.html" file. My intention was to find "index.html" with exact content because i messed up tomcat installation and i have to recover the original "index.html" file i lost.

Furthermore, i took this research as exercise for practice the "find" option and passing arguments to that.

The fact is that "index.html" is a common file and you can find out several inside your system but i need the one i wrote "/var/www/index.html" inside.

I found out at last so it's not a problem anymore but that would become interesting to figure out a way for discover a common file but with a specific content.
