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.
Fortran has the equivalent of Unix file descriptors: By convention, many Fortran implementations use unit numbers UNIT=5 for stdin, UNIT=6 for stdout and UNIT=0 for stderr. In Fortran-2003, the intrinsic ISO_FORTRAN_ENV module was standardized to include the named constants INPUT_UNIT , OUTPUT_UNIT , and ERROR_UNIT to portably specify the unit ...
Example usage of tee: The output of ls -l is redirected to tee which copies them to the file file.txt and to the pager less. The name tee comes from this scheme - it looks like the capital letter T. The tee command is normally used to split the output of a program so that it can be both displayed and saved in a file. The command can be used to ...

This aspect is used to specify the standard streams (stdin, stdout and stderr) of the new program. A successful overlay destroys the previous memory address space of the process, and all its memory areas, that were not shared, are reclaimed by the operating system. Consequently, all its data that were not passed to the new program, or otherwise ...
