using that process, process number, what date it started, how long it’s

• you can kill the process by typing, “#kill (process number)”

• reports number of free files system disk blocks
• use df –k to list in kilobytes (KB). this lists space used and space available
for all mounted file systems
• use df –l to list local file systems only
• use df –F nfs –e for number of free files on all nfs mounted file systems (-
F =file system)
