In the parent process do the following: • print it's own PID • print it's child's PID • wait for the child to die using the wait() syscall. • when the child is dead, print a message that says so. Feb 11 '08 #3 reply Arul...
Linux parent process and child process when 'sudo' 如果在一般用户下如user,执行sudo命令,会产生两个进程。 ps -ef | grep Container root 4305 643 0 16:37 pts/39 00:00:00 sudo ./ContainerCompilation.sh root 4306 4305 0 16:37 pts/39 00:00:00 /bin/bash ./ContainerCompilation.sh 4306进程...
To put this into context, let’s assume process5with aPIDof5050starts process6. Process 6 will be assigned a uniquePIDsuch as6670, but will still be given thePPIDof5050. The parent process here is process5and the child process is6. The child process is assigned a uniquePIDbut thePPIDis...
Pstree displays the process parent-child relationship in a hierarchical format on Linux. We can use this command to find the parent or child process easily. The output of this command is quite similar to the output of the ps axjf command and the ps -ef –forest command. But pstree re...
The process created by the kernel is known as the “Parent Process,” and all the processes derived from the parent process are termed as “Child Processes.” A single process may consist of several child processes having a unique PID but with the same P

\n");printf("Here I am before use of forking\n");printf("I am the PARENT process and pid is : %d\n",getpid()); pid1 = fork( );if(pid1 ==0) {printf("\n\nHere I am just after child forking1\n");printf("I am the Child process and pid1 is :%d\n",getpid());...
When forking a child process, the parent write-protects anonymous pages and COW-shares them with the child being forked using copy_present_pte(). We must not take any concurrent page faults on the source vma's as they are being processed, as we expect both the vma and the pte's behind...
Because it sounds like you are setting up a daemon (in which it is very common to fork() and let the parent die), you should also make a call to setsid() in the child immediately after doing the fork(). This detaches the calling process from the parent and makes it a process grou...
