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!

Word header does not print correctly

Ever printed a document and set the header as 1 inch. After printing the header is adjusted and it’s not the same with the specified settings on the header.
There are numerous solutions to this single issue. Updating printer driver may help to solve this problem. Selecting the proper size of the document before printing that is same size with the paper that is on the printer. And a lot of possible solutions.
Another solution to solve this issue is to check the headers and footers on page setup. On the document click on “File”, click “Print”. On the Print window, click “Page Setup” at the bottom on this window. See image below:

On “Page Setup” window, click the “Layout” tab and adjust the “Headers and Footers” as per requirement. See image below:

After adjust to a desired setting, click “Print” and if everything goes well. Then the printing will be as expected.

Cheers..till next time.

Add multiple drivers to a WinPE image

How to add multiple inf drivers to a Windows PE Image?

To add a single driver to a Windows PE Image  is quite straight forward but adding multiple drivers  one by one is not ideal or else it will take a definite amount of time.

Dism command provides an option to add a single driver or add multiple drivers.

To add a single driver or multiple drivers, the first thing to do is to mount the image for editing.

Dism /Mount-Image /ImageFile:"C:\WinPE_amd64\sources\boot.wim" /index:1 /MountDir:"C:\WinPE_amd64\mount"

C:\WinPE_amd64\media\sources\boot.wim -  is the image where the new drivers will be added

C:\WinPE_amd64\mount - this directory will contain the extracted files of wim images, the folder must be created if it doesn't exist

Once the image has been mounted, to add a single driver type the command below:

Dism /Add-Driver /Image:"C:\WinPE_amd64\mount" /Driver:"C:\Folder_Driver\driver.inf"

C:\WinPE_amd64\mount - the folder in which the mount i…

Move folders in command line with specific string

How to move folders in command line without selecting manually the folders?
Manually moving folders is quite ideal if there are two or three folders that needs to be moved. But if the folders are quite a lot and doing it manually is a bit tedious; besides chances are there might be folders that will be missed out.
Command lines and some basic editing in notepad can ease the process of moving folders it can be run via batch file or just simply enter the command at the command prompt window.
Assume that all folders have the word “old-data” as part of its folder name. It can be any string as long as it’s common to all the folders that needs to be moved or archived.
First step, is to open a command prompt window then change directory to the folders.
Example: c:\cd sales_data
Then at sales_data directory type:
dir *old-data* /s/b > file_old_data.txt
replace old-data with any string that is common to all folders.
* is used between the string, which basically means that look for folders with this …

Check if 32 bit or 64 bit processor from command line

How to check processor architecture whether its 32bit or 64bit?
One method is to query the registry from the command line.
Here’s a one liner command line that will check whether the PC processor is 32bit or 64bit.
reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" | find “ARCHITECTURE”
If the output is something like this:

Then it’s a 64bit, if it shows x86 then it’s a 32 bit.
reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" | find “IDENTIFIER”
Above query can also identify, the output shows Intel64 for 64bit.
Sample Output: PROCESSOR_IDENTIFIERREG_SZIntel64 Family 6 Model 142 Stepping 10, GenuineIntel

Omitting the find option from the “reg query” command will show quite a few information.
reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
This query command works in Windows 7, Windows 8 and Windows 10. I believe this will also work in Windows s…

Linux copy files and change date or time

So, you want to copy files from one folder to another folder and change both the source and destination timestamp?
Linux can easily change or modify the timestamp with ‘touch’ command.
A one liner command with the help of ‘pipe’ to pass the arguments and ‘xargs’ to execute multiple commands in a single line can easily accomplish this task.
Command below will copy the files in the current directory where ‘ls’ command is executed to the directory ‘xfiles’, timestamp will be changed to 7 hours less from the current time.
ls | xargs -I % sh -c 'touch -d "7 hours ago" %; cp -p % ./xfiles';
-p option is important to preserve the modified timestamp
Note: the above command will change the timestamp for both source files and destination files.
Command below will change the source timestamp, but the destination timestamp will be the date and time that the command was executed.
ls | xargs -I % sh -c 'touch -d "2 Aug" %; cp % ./x';

Notice, that the -p option is omitted …
