The reason for this is to distinguish between a file named '1' and stdout, i.e. cat file 2 >1 vs cat file 2 > & 1. In the first case, stderr is redirected to a file named ' 1 ' and in the second, stderr is redirected to stdout. Another useful capability is to redirect one standard file handle to another.
In the case of an interactive shell, that is usually the text terminal which initiated the program. The file descriptor for standard output is 1 (one); the POSIX <unistd.h> definition is STDOUT_FILENO; the corresponding C <stdio.h> variable is FILE* stdout; similarly, the C++ <iostream> variable is std::cout.
Similarly, both the stdout and stderr output streams can be redirected to standard output and the program.lint using stream redirection: lint program.c 2 > & 1 | tee program.lint To view and append the output from a command to an existing file:
By default, when csh runs a command, the command inherits the csh's stdio file handles for stdin, stdout and stderr, which normally all point to the console window where the C shell is running. The i/o redirection operators allow the command to use a file instead for input or output.

File descriptors for a single process, file table and inode table. Note that multiple file descriptors can refer to the same file table entry (e.g., as a result of the dup system call [3]: 104 ) and that multiple file table entries can in turn refer to the same inode (if it has been opened multiple times; the table is still simplified because it represents inodes by file names, even though an ...
