Empty log or replace large files

Log files can easily occupy the space of a drive.

If the log files is collecting or monitoring multiple system then chances are it will grow in size very quickly.

If it the log file is in a text format, even if it comes in Giga or Tera bytes size it can be emptied very quickly in a command line.

If the log files has been analyzed or not in use anymore, then it is a good candidate to get rid of it rather than occupy the space of a drive for nothing.

To empty a log file or a text file:

In Windows open command prompt and type:

echo "First Line" > Packets_2018.log

The log file will be replace with the word "First Line" and only a few bytes in size. Whatever was the content before on that log file is ditch away. So, be careful in emptying a file it's not reversible,

In Linux open Terminal and type:

echo "Line 1" > Packet_logstash.log

Till next time..Cheers!

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

However, if the file (ex. an ISO file) and is more than 4GB and the filesystem  of the thumbdrive or the storage is FAT system, then robocopy or any methods of copying will not work. Since FAT has a file size limitation of less than 3GB.

Robocopy is free it can be accessed from command line. No ne…

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username.
WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided.
Why would you need a command line tool if there’s a GUI to check?
If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username.
If you have remote computers, you need to delegate someone in the remote office or location to check.
Or you can just write a batch file or script to automate the task.
Here’s the code below on how get computer model, manufacturer and the username.
Open an elevated command prompt and type:
wmic computersystem get "Model","Manufacturer", "Name", "UserName"
Just copy and paste the code above, the word “computersystem” does not need to be change to a computer name.
A sample output below will be generated if the co…
