Disk usage is a critical thing in servers, Certain times the web service or server acts weird and it could be disk space being full.
In order to check the disk space we can use “df” command in unix. which will show us the disk/file system, used and available disk quantity. also the mount location of the disk.
We have discussed below listed commands

Here we are going to see how to Check the port used by any process in unix?
Check the port used by any process in unix?
Here is how you can check port used by any process in unix terminal.

Before such thing happens, better to check the port is being used by any process already to avoid such conflicts. Its saves us more time.
We have discussed below listed commands
netstat – network utility used for checking the connection of TCP/UDP ss – Socket statistics, similar to netstat but faster. sudo – Run any command with root or super user level/mode.
