Well, the message you're getting is printed on stderr (as opposed to stdout, which is where normal output goes). If you want to just get rid of that stream, this is the easiest way.
Many times it can be useful to ignore all output and just check the return value of command to see whether it exited normally or not:
Redirection &> will redirect both stdout and stderr.
You can specify where does this message go, by manipulating the stderr stream. Stderr is associated by a file descriptor 2 (/dev/fd/2 in bash).
Other than redirecting it to /dev/null, you could redirect it to a file, to capture the stderr, like
or '2>>' to append.
I have to read a file line by line, change it and then update the file. Problem is, when i read the file, "read" command ignores leading spaces.
The file is a script which is indented in many places for clarity. How to i make "read" command read leading spaces as well. (3 Replies)

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.
