The command mount shows which file system (device and type) is mounted at which mount point:
$ mount /dev/hdb2 on / type ext2 (rw) proc on /proc type proc (rw) devpts on /dev/pts type devpts (rw,mode=0620,gid=5) /dev/hda1 on /data type ext2 (rw) shmfs on /dev/shm type shm (rw) usbdevfs on /proc/bus/usb type usbdevfs (rw) automount(pid1012) on /suse type autofs \ (rw,fd=5,pgrp=1012,minproto=2,maxproto=3) totan:/real-home/jj on /suse/jj type nfs \ (rw,nosuid,rsize=8192,wsize=8192,hard,intr,nolock,addr=10.10.0.1)
Obtain information about total usage of the file systems with the command df. The parameter -h (or --human-readable) transforms the output into a form understandable for common users.
$ df -h Filesystem Size Used Avail Use% Mounted on /dev/hdb2 7.4G 5.1G 2.0G 73% / /dev/hda1 74G 5.8G 65G 9% /data shmfs 252M 0 252M 0% /dev/shm totan:/real-home/jj 350G 324G 27G 93% /suse/jj
Users of the NFS file server totan should clear their home directory immediately.
Display the total size of all the files in a given directory and its subdirectories with the command du. The parameter -s suppresses the output of detailed information. -h again transforms the data into a form that ordinary people can understand. With this command:
$ du -sh ~ 361M /suse/jj
see how much space your own home directory occupies.
