Did you copy Corona688's script char by char, keystroke by keystroke? The $ - signs are important for variable expansion.
The pipe symbol | connects (pipes) one command's standard output (stdout) to another's standard input (stdin). With it, you can construct powerful, versatile compound commands from single simple tools / commands.
/dev/stdin is a (formal) symbolic link to a process' stdin, used in case a command explicitely needs a file name as an argument.

Is there any system call available in AIX to read the size of raw disk?
If I use the command "lspv -L",it only gives size of PVs on which file system is there. I need to extract the size raw disk i.e. file system is not there on the disk.

stderr
FD(4) BSD Kernel Interfaces Manual FD(4)
NAME
fd, stdin, stdout, stderr -- file descriptor files
DESCRIPTION
The files /dev/fd/0 through /dev/fd/# refer to file descriptors which can be accessed through the file system. If the file descriptor is
open and the mode the file is being opened with is a subset of the mode of the existing descriptor, the call:
fd = open("/dev/fd/0", mode);
and the call:
fd = fcntl(0, F_DUPFD, 0);
are equivalent.
Opening the files /dev/stdin, /dev/stdout and /dev/stderr is equivalent to the following calls:
fd = fcntl(STDIN_FILENO, F_DUPFD, 0);
fd = fcntl(STDOUT_FILENO, F_DUPFD, 0);
fd = fcntl(STDERR_FILENO, F_DUPFD, 0);
Flags to the open(2) call other than O_RDONLY, O_WRONLY and O_RDWR are ignored.
IMPLEMENTATION NOTES
By default, /dev/fd is provided by devfs(5), which provides nodes for the first three file descriptors. Some sites may require nodes for
additional file descriptors; these can be made available by mounting fdescfs(5) on /dev/fd.

/dev/fd/#
/dev/stdin
/dev/stdout
/dev/stderr
