Linux change hostname without rebooting

Changing hostname in Linux without rebooting, is quite straight forward. Changing the hostname will also change the name on the Terminal prompt, and will be displayed beside the current login user on the system.

Open a terminal window and edit /etc/hostname. Use vi, nano or even echo command to change the content or value of the hostname file.

Then type this:

sysctl kernel.hostname=new-hostname-office.internal

After typing the command, if the new hostname doesn't appear yet. Disconnect from SSH and login again via SSH and the new name will be displayed.

That's it, simple as that.



If unsure, try on a VM before applying to production. And check whether the desired output is the expected result.
Cheers! Till next time.

The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only. But then the person printing the file accidentally chooses “A4 Cover” then this error 016-799 will occur. ...

Delete Directories with Wildcards using rd or rmdir

  Deleting files in command prompt using wildcards is quite straight forward. Command below will delete all text (".txt") files on the specified path.      Del D:\txtlog\*.txt Command above will delete all files with ".txt" extension in d:\txtlog directory. Easy enough to delete all matching files. Using the same method with rmdir or rd command this will not work. For example, if we have a directory on d drive that is auto-generated by an application and the filename is consistent with a pattern plus incrementing number at the end to differentiate the folder from other folders.    D:\baklogs\log1\    D:\baklogs\log2\    D:\baklogs\log3\    Etc..    D:\baklogs\log100\ The folder name has a consistent pattern that is preceded by the word “log” plus incrementing number. If the command below is executed to remove the directories in one go, an error is shown which h...
