What do you know about Linux permissions
When viewing file permissions on Linux, sometimes you see more than ordinary R, W, X and – names. What you may see is not RWX, but s or T, as shown in the following example: drwxrwsrwt One way to further clarify this is to use the stat command to view permissions. The fourth line in […]
How to correctly handle the zombie process on the Linux Data Center Server
Linux processes often go astray, do nothing, or even consume CPU cycles. Although zombie processes do not occupy valuable resources like running rogue applications, they may pose a threat. How does it pose a threat? When a process becomes a zombie process, it retains its process ID (PID). Because the number of PIDs in Linux […]
