No more existing process still accept kill -0
Issue
In order to synchronize two processes, kill -0
signal is used, but also if the precess is no more shown by ps -ef
command nor in the /proc
directory, the kill command does not return 0
in $?
.
The process ID is 8372 but , also if the ls /proc
doesn't show the directory, it is accessible via cd /proc/8372
.
