Create a new text file with content in Linux



Touch command in Linux will create an empty file in Linux command line. If no other parameters is specified whether a line will be inserted to the newly created file.

Cat command is for reading files via command line but it can also be used to create a file in Linux terminal window command line.

Cat command below will create a file called “test_comment.txt” and with the content or the line of “Hello World of Touch and Create File” on the file created.

Here’s the shell command:

cat  <( echo “Hello World of Touch and Create File”)  >  test_comment.txt

Note that there is no space between “<(“, if there is a space then the command will not work as expected.

Touch command to create a new file and also insert a new line or insert a string on the newly created file.

Here’s the shell command:

touch touch_file_comment.txt; echo “Hello World of Touch, insert this line.” >  touch_file_comment.txt


Basically, the command executes two commands separated by “;” semi-colon. The first part is to create a file and the second command is the echo command to insert the line to the newly created file by touch.

man touch has a lot of other usage, it can be used to modify timestamp as well.

Above commands works fine; just an illustration on how to learn basic commands on Linux terminal line but on a production environment, I am not sure what scenario it would suit best.



Cheers. Enjoy Linux!!!

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.

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.

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.
