The sequence below will write each line to row 2 of the screen.
If you can arrange the output of your commands to start with a prefix, you
could parse the prefix from the parallel output to set the row and then replace
the \033[2;1H sequence with \033[${row};1H
while read -r line ; do echo "\033[2;1H\033[2K$line" ; done

Subject: Possible to have fixed output positions for multiple commands
Is it possible to make parallel run multiple commands
$ parallel cmd ::: A B C
And display the output as
$ parallel cmd ::: A B C
A: <last line from cmd A>
B: <last line from cmd B>
C: <last line from cmd C>
Where the last line from each command output is always displayed
in-place in real time at the same position, overwriting the previous
line from the same command, and the name to identify each command is
configurable by the user?
I skimmed through the document, couldn't really find the answer.
Wonder if it's possible at all?
