So I'm trying to run a bash
script to cycle through them to purge them.
I've found multiple answers that suggest using a bash for loop then
doing something like:
echo "purge volume ${volname} yes" | bconsole - where $volname
is created by the for loop -
should work. And it does actually to a point. It will invoke the "purge
volume" dialogue then asks which pool to use. Inserting the pool number
after the volume command (e.g. echo "purge volume 2 ${volname} yes" |
bconsole) doesn't work either. Nor does inserting \n into the echoed
command at various points.
Being able to put bconsole commands into a bash script seems like
something that will be generally useful but I can't find a way to make
it work.
Any ideas?
This works for me in a slightly different scenario:
------------------ cut here ------------------
bconsole <<END_OF_COMMANDS
release storage=LTO1-Drive
quit
END_OF_COMMANDS
------------------ cut here ------------------
Note the "empty" lines between the lines with the release and the quit
command which "simulate" pressing return. However, I'm not sure if you
can use variable within this "here document" structure or if the
variable name will be interpreted as verbatim input. In the latter case,
you might, for example, first create a temporary script file with the
appropriate commands and run that from your main script. (Yes, sounds
like an ugly hack...)
HTH,
