When I create a new file named 0 on my VPS, I always get a directory 0 instead of the file.
It happens in the case when I upload a file 0 or create a file by touch 0.
It seems that 0 has a special meaning on ext3 Linux file system.
Could you advise on it?
Additionally, how can I create a 0 file on Node.js?
This was actually not an error and was related to the UI issue File Manager in Cpanel.
In File Manager it (0) looks like a folder, but it must be a file. I confirmed it by cat 0.

I read that "1" is the number of hard links to the specific file, but what exactly are hard links?
In computing, a hard link is a directory entry that associates a name
with a file on a file system. All directory-based file systems must
have at least one hard link giving the original name for each file.
The term “hard link” is usually only used in file systems that allow
more than one hard link for the same file.

I have a question if I want to create a file without using command or programming?
I know mkdir hi.txt, but is there any way to make without using these?
The touch PATH program will create an empty file at the location entered for PATH.
Example: touch /var/tmp/file.txt will create an empty file at /var/tmp/file.txt
If you want to create a file in Linux, without using any program/command,
you can use > this sign
like > hi.txt it will create a file

When I try to cat in one file, for exemple cert.pem I receive ab error: No such file or directory
These are symbolic links - special files that just contain the path to another file. When you cat them, they essentially redirect to the file they link to. However, as evident by the red color in the ls output, these links are broken - they point to files that do not exist, and thus you get that error when you try to cat them.

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.

How to check 2 same files for any data corruption while transferring it to from one OS(Linux) to another OS (Open VMS).
--- I am creating a single file on linux machine ,and transferring it by using sftp on to ovms machine.
Now, how do I check if the data in the files which I have sent is same or has been corrupted while transfer??
Based on the thread in Super User How to check if a file is corrupt or not? , what about doing a checksum?
$ cksum faaa
4294967295 0 faaa
before sending it and after. Then compare the values. If equal, the sftp transfer was successful.
