Gentlemen,
I'm now running three machines here, each with several copies of
various linii available. It gets a bit confusing. I'm wondering if
there might be something I can add to my prompt that could help me
remind myself where I'm at. I'm open to any suggestions, but one
idea I had was something to identify the volume label of the current
root directory. That would do it if it can be done. Can it?
Other people have offered some alternatives, but if you really want
the volume label of the current root directory:
volume_label=$(eval "$(blkid -o export $(mount | awk '$3 == "/" {
print $1 }'))" ; printf "%s" $LABEL)
`blkid` is a Linux thing, AFAIK.
