If following is the usage of cat /proc/meminfo

MemTotal: 4051304 kB
MemFree: 28544 kB
Buffers: 216848 kB
Cached: 3398628 kB
SwapCached: 0 kB
Active: 455460 kB
Inactive: 3291612 kB
HighTotal: 0 kB
HighFree: 0 kB
LowTotal: 4051304 kB
LowFree: 28544 kB
SwapTotal: 4200988 kB
SwapFree: 4195304 kB
Dirty: 188 kB
Writeback: 0 kB
AnonPages: 130000 kB
Mapped: 47360 kB
Slab: 249036 kB
CommitLimit: 6226640 kB
Committed_AS: 1400364 kB
PageTables: 4512 kB
VmallocTotal: 34359738367 kB
VmallocUsed: 9236 kB
VmallocChunk: 34359727099 kB
HugePages_Total: 0
HugePages_Free: 0
HugePages_Rsvd: 0
Hugepagesize: 2048 kB

Then what means "Inactive: 3291612 kB" processes. Here my memory usage is almost 100% but how can i find which perticular processes are consuming all each percent of this 100 % .

Also in this situation my SWAP usage is 0%.

Please help.

there are many commands to see the process status
top
topas
vmstat etc..etc..

True, But how can i get list each of process which is consuming each percentage of total memory.

Top and vmstat shows very compact output...

you can use dimstat software for this. Its free software . I use this for my performance test activity and its really a good monitoring tool.

Dimitri has not been updated in one year.

I advise caution when considering software that is not actively maintained.

If you use top in batch mode you get a list of all processes:
top -b -n 1 > list_of_processes

Before that, if you want the output sorted by memory usage you can do the following:
top
M (this sorts the output on the screen by memory usage)
W (this writes the sort settings to a configuration file ~/.toprc; this settings are used when you then start top in batch mode as described above)
