Is it possible to add options to the different commands in pactl and
pacmd to format output in a tabular style, this to make it easier to
parse the output with sed and/or awk.
One example: I wan't to unload all null sinks, I need to use
list-modules to get hold of the indices, the problem is that the report
have index: and name on different lines, with a tabular layout with all
module info separated by tabs or whitespace one line for each module. I
can do this using a pipe something like this:
echo ... |pacmd|sed ... | pacmd
where the substitutions to be done for the ... s are fairly simple.
It is possible to do it whith the current setup too but the sed scripts
have to be much more complex, these scripts are best written as
multiliners, involving sed's holdspace.
