[Wolves] defrag

[Mo Awkati]

Hi Peter
 
I'll have a go with your approach as well. I presume fuser is an application?? 
 
All the LUG contributions are helping me get to grips with the command line work. I have got hold of O'Reilly's Linux in a Nutshell so I am hoping with your help I can get to speed with things. :-)

Assuming that David knows KDE better than me and has correctly diagnosed
your problem, you can roll this all up into one command with fuser. If
your floppy is mounted on /mnt/floppy,

fuser -m /mnt/floppy -k -TERM # ask nicely for programs to exit
fuser -m /mnt/floppy -k -KILL # make programs die messily
