Reading uncommented line in Linux and Windows

Reading uncommented line is almost a daily live for most Linux and Windows Sys Admin.
Uncommented in .conf or .ini lines are the active or the lines that are currently in used for the loaded configuration.
In Linux, it's quite straight forward to do it using grep.

grep ^[^#] service_file.conf

The above command uses regex, to search for lines in the .conf file that doesn't start with #.
In regex ^ means the first character, but if it is inside the brackets it has other meaning. It negates whatever character that follows.
So, the regex means search the first character that doesn't start with #.
Technically, it's teling grep to search for uncommented lines.


Yes, the above solution is for Linux.
How can we do it in Windows?
Well, it turns out to be almost the same but with a little twist of course since its a different operating system.
So, here's how we can do it in Windows.

findstr /b /v ^# file.txt

Hopefully, it makes life easier and the above commands comes in handy the next time you read .conf or .ini for uncommented lines or config.
Here's a sample image for Windows.

Till next time..Ciao!

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username.

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.

Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. 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.
