Someone had spawned a while true loop in bash (logged in as root) on a server. It kept spawning processes, which fortunately exited but I needed to kill the parent. I came to know it was spawned directly from command line and not from a script, so I grepped for '-bash' and killed those processes owned by root. It worked fine.
When you do
ps aux, In the command column different variants of bash show up.
/bin/bash -bash -bash -bash /bin/bash bash /bin/bash /bin/bash bash
What are the differences?
