Solaris

I want to check system memory
Usage of CPU and disk and report number of free disk block in Sun Solaris
How can I do
Help me

sar will show you CPU, memory utilization, and disk I/O
(man sar)

$ df -k

will show you free blocks and percentage of mounted filesystems
for non-root users.

If you need to find out unallocated blocks of disks
(or if you also need to find out raw device allocations)
you would have to inspect the disks' vtocs,
which involves a bit of block arithmetics on your behalf
(best to be put in a script)
For instance you could have a glance at what your disks' vtocs look like
(but beware if you have alternate paths not to count twice)
by e.g.

# echo|format|sed 's,.*\(c[0-9]*t[0-9]*d[0-9]*\).*,/dev/rdsk/\1s2,'|grep dsk|xargs prtvtoc|more

Note, the 2nd slice of BSD like disk labels (Solaris inherited from BSD because it was an offspring) refers to the whole disk (man prtvtoc)

To view CPU and Memory utilisation over a 10 second period (as well as other stats)...

vmstat 1 10

man vmstat
