Bash user function (typically executed from an interactive shell while doing system work or just stuff) on GNU-Linux. Point is see mounted disk devices neatly printed.

Bash GNU-Linux DiskMountReporter

## earlier version was fubar

function diskmounts {
    cat /proc/mounts | perl -nawl \
   -e 'if ($F[0]=~ m{/dev/(loop[[:digit:]]+ | sd[a-z][[:digit:]]? | sr[[:digit:]]+) | UUID= | LABEL=}x) {' \
   -e '  push @dp=>[@F[0,1]]' \
   -e '} END {print for map { $_->[1] } sort {$a->[0] cmp $b->[0]} map { [$_->[0], join (qq[\t\t],@$_)] }@dp}'
}

Output looks like this:

/dev/sda1 /boot
/dev/sda4 /
/dev/sda5 /var
/dev/sdb1 /media/usb0
/dev/sdb5 /media/usb3
