I apologize in advance in the case my English is not good (it's not my native language).
The only difference I can tell is when opening a directory. I can open only if I have execute permissions to see what's inside of it.
But I guess there might be more differences. Perhaps a file that doesn't have execute permissions can't "pass" through the kernel. I really don't know.
I've been searching for examples about this differences but I couldn't find anything.
For a directory, execute permission controls the ability to access files and subdirectories contained within it.
For a file, execute permission controls whether you can execute the file as a command.

I have the following challenge under Linux:
An application is writing a config-file "samename.cfg" into certain directories
I want to have the config-file named different for each directory
I do not want any file called "samename.cfg" written to the directories
I can not change it in the application
So I would like to have the application thinking that it accesses samename.cfg but in fact it reads and writes anothername.cfg. Symlink does not help, because then there still is a file called samename.cfg in every directory.
Anybody any idea?
Regards,
Axel
Try using a hard link instead of a soft link when using ln command (just remove the -s flag).
See ln man's page for more details.

I just coded a script in bash on Ubuntu but I don't know where I should put it...
I read I had to put it in /usr/bin in a tutorial but maybe it's better directly in /bin ?
This is the difference between both directories:
/bin
It contains commands that can be used by both the system administrator and the users, but which are necessary when other file systems are not mounted (for example, in single user mode). It can also contain commands that scripts use indirectly
/usr/bin/
This is the main directory of executable commands in the system.
Therefore, it will work on both, but you must establish what responsibility your script has.

I am making a folder where there are some shared files which can be read and written by anyone (but not executable) in a server. But I don't know what kind of owner and group are used for the files. Are there any special or well known owner or group for the purpose? Thank you very much.
The best approach to do this would be to use:
chmod 110
This will change file permission to read & write, no execute

Most likely a rather obvious question but nevertheless I am doubtful about it. For development purpose our team got an linux VM tot work on. Once in a while I met a lost+found directory. Most of the time it is not accessible (permission denied). What is the meaning of this directory. Has it been implemented by Linux or has it been manually by one of the administrators?
I do agree with #Arcturus-B and I put some effort in it to get some extra informatie. I found info at https://unix.stackexchange.com/questions/18154/what-is-the-purpose-of-the-lostfound-folder-in-linux-and-unix and http://www.linuxnix.com/2012/12/lostfound-directory-linuxunix.html I guess I was a little bit cautious and did expect to find so much detailed information about this.
Files that are being open when an unexpected shutdown occurs may be damaged. On the following power up, the fsck tool is run to try to recover them. If any file is to be recovered, it is placed in the lost+found directory of the partition the original was stored in.

I am using Cent-OS and I am trying to copy a file. I su to root first, then I execute:
cp test.txt /usr/java/jdk1.7.0_45/jre/lib/management
But I get an input/output error. Why can't I copy this file as root? Is there something that can lock a folder in Linux so root can't change it?
root is a concept to get around the system's permissions.
IO error is a more physical problem that could be of a much more varied nature. Common examples included faulty media, unreadable CDs, lost connection, and so on.
