Linux command for paging?

Anyone who can help me with a command which can display linux paging(related to virtual memory)?

Are you looking at these commands ?

Code:

vmstat

top

free

How can I detect if paing is happening with that command?What pages-in and what pages-out?

linux uses swap space as paging file can we change swap space as we change in windows?like can we increase or decrease swap space while running linux in any runlevel??anybody please

The following is the top o/p from my desktop:

Quote:

top - 18:42:39 up 5:33, 2 users, load average: 0.18, 0.17, 0.17
Tasks: 165 total, 3 running, 162 sleeping, 0 stopped, 0 zombie
Cpu(s): 2.8%us, 2.5%sy, 0.0%ni, 94.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st

Here you can see that from the last line of the above quoted message that some part of the swap space is in use.

You can dynamically increase/decrease swap size. To increase

Code:

swapon /dev/<harddisk_partition>

To decrease:

Code:

swapoff /dev/<harddisk_partition>

Be careful while manually turning on the swap space as you may accidentally give some other hard disk partition which may corrupt all the data on that partition

determine the virtual pages

how can I print the virtual pages allocated to the currently running processes on my system and also the page faults associated with them?
