By the way, what I wanted to do when I encountered this "stupid"
problem with -f flag, if not "clever", might at least be usefull for
other people. I wanted to add to wmii some basic ability to deal with
USB pens:
- mount and open them automatically when plugged in;
- show them as buttons in the right bar, with focus or normal colors
depending on whether their file system is mounted or unmounted;
- unmount/remount them by simple clicks on their buttons.
It might be that your removable device manager skvm does this job
perfectly, I don't know. The point is that skvm is not available in
the core repository of Arch Linux, the distro I'm using from now on,
and I do not use to compile programs from source. So I have found a
way to add this feature with wmii-3.9.2 just by modifying
appropriately the wmiirc file. If some people are interested, this is
available here:
skvm scares me, not least because it's ugly and I can't even
figure out quite what it does. I'm not terribly fond of pmount
either. I'm currently using a (heavily) modified hal-based
mounting script that does the job quite nicely. Attached.
Your script does look useful though. I'll have to have a good
look at it later. I tend to use the commandline or wimenu, but I
think that for the purposes of your script I'd have used
wmii9menu.

Most software today is very much like an Egyptian pyramid with
millions of bricks piled on top of each other, with no structural
integrity, but just done by brute force and thousands of slaves.

HalMount mounts and unmounts using hal (via dbus)
Usage: $PROG -h|--help
$MOUNTNAME -l
$MOUNTNAME [-t <fstype>] [-o <options>] <device> [destdir]
$UMOUNTNAME -l
$UMOUNTNAME [-o <options>] <device|destdir>
-h|--help - Displays this help
-l - List available devices for mounting/unmounting
-t <fstype> - Filesystem type (default: auto)
-o <options> - Mount options
<device> - Label, UUID or device node of device to mount (eg:
/dev/sdb1)
<destdir> - Destination mount directory (under /media, default:
<device label>)
Examples:
$MOUNTNAME /dev/sdb1
$MOUNTNAME 'APPLE IPOD' iPod
$UMOUNTNAME 'APPLE IPOD'
