RELATED IDEAS

Change the behavior of standard output of the Korn shell same as the Bash

See this idea on ideas.ibm.com

The close timing of standard output redirected to tee via the pipe as shown in the following sample shell in Use Case is

in case of the Korn shell:
-just after the first ‘echo 0' command is completed. Because standard output of the third ‘echo 1' command is redirected to /dev/null, there is no standard output to tee. So ‘tee' command is completed immediately just after the first ‘echo 0' command is completed.
-As a result, the passing of command execution occurs.
-The order of execution of these commands is
1. echo “0”
2. sleep 1
3. echo “2”
4. echo “1”.

in case of the Bash:
-after the third ‘echo 1' command is completed. So ‘tee' command is completed after the third ‘echo 1' command is completed.
-As a result, these commands are executed sequentially as the coding order.
-The order of execution of these is
1. echo “0”
2. sleep 1
3. echo “1”
4. echo “2”.

This behavior of the Bash is expected from the viewpoint of a programmer than the Korn shell.
Customer has requested for change or add to this behavior of the Korn shell.
