Hi
What is the command to find only the zombie processes??
How to write the code in C to fetch the no. of zombie processes??
Thanx
Hi,
Use Normal ps command.
# ps aux | awk '{ print $8 " " $2 }' | grep -w Z
Z 4104
Z 5320
Z 2945
To kill a zombie
# kill -9 4104
Sometimes zombie cannot be killed so the solution is to kill the parent process.
The use of grep to post-process awk output is kind-of aberrant; just use awk to figure out which lines have a Z.
ps aux | awk '$8=="Z" { print $2 }'
ps output is somewhat platform-dependent (this seems to work on Linux at least, but might need tweaks for other architectures), and obtaining this information from the kernel on the C level doubly so. On Linux, the proc pseudo-filesystem provides this information. See the proc(5) manual page.
thanx a lot..
ther is no zombie process currently present in my system. is it possible to create a zombie process?? so that i can see the output.
In C, have the parent process fork and exec a child process. And then make the parent exit without waiting on the child. This will result in the child process becoming a zombie.
thanq sooo much...
