Get Thread count , Used memory for a particular Process
Hello All,
I've several question related to the Process information gathering in Linux which use the "ps" functionality. My problem is 1. How to get the Tread count for particular process name(or the command such as gedit,skype,eclipse) eg: ps -elm|grep $pid|grep -v grep |wc -l in this example it use the PID what i actually want is to get the thread count using the process name 2. How to get the memory size in MB for a given process name or PID using greap functionality such as in the above example. 3. How to search a process is exist or not using the given process name or PID using greap as above example. 4. How to find the main module which need to run the process name or PID using greap. Please help me on this matter ...... Thank you in Advance Hasantha |
what about your effort? what you tried?

Note: this will print the process details if it is existing along with the command we used which is grep. like the following: [lokesh@computer ~]$ ps aux | grep 2338 lokesh 2338 0.1 0.3 4840 1524 pts/0 Ss 11:00 0:00 bash lokesh 2371 0.0 0.1 4044 668 pts/0 R+ 11:01 0:00 grep 2338 if the process with id 2338 is not existing the the result will be like this. [lokesh@computer ~]$ ps aux | grep 2338 lokesh 2371 0.0 0.1 4044 668 pts/0 R+ 11:01 0:00 grep 2338 Don't get confused. |

Hello Chakka,
Thank you for the quick respond. really appreciate your effort. for the 2nd Question i actually need to get the process memory size in MB look the below example m looking for [lokesh@computer ~]$ ps aux | grep PID ...... something 20 MB ... or the size of the process for the 4th Question what i want is to get the CMD for a particular process EG: ps -ef .... something .. usr/lib/libstdc++.so.6 (what i really need to get only the CMD) so if i use that CMD value and execute i need to get a fresh application for that. Thanks in advance again Hasantha |
for your second question, i didn't found anywhere ps is giving direct memory details.
with respect to your fourth, what is this CMD? Do you mean command? If it is have a look at the last column of the ps aux command. |
