The following examples show various ways to redirect stdin and stdout for the UNIX system.
Example 1
This example specifies both an input file and an output file. The Teradata TPump script is in /home/tpuser/tests/test1 and the job output is written to /home/tpuser/tests/out1.
tpump </home/tpuser/tests/test1 >/home/tpuser/tests/out1
Example 2
This example specifies only an input file. The Teradata TPump script is in /home/tpuser/tests/test1 and the job output is written to stdout, which ordinarily would be the terminal.
tpump </home/tpuser/tests/test1
Example 3
This example specifies only an output file. Enter the TPump script via stdin, normally at the terminal. When input is complete, type Ctrl-D to indicate end-of-file. Type Ctrl-D by simultaneously pressing the Control key and the letter D. The job output is written to /home/tpuser/tests/out1.
tpump >/home/tpuser/tests/out1
Example 4
This example specifies neither an input nor an output file. Teradata TPump commands are typed at a terminal via stdin and job output is written to the terminal via stdout.
