Sort running process using command line




In Linux, grep can be used to sort running processes via the terminal or command line.

It can easily be done by typing ps ax then pipe grep and the filter parameters.

Example: ps ax | grep "mail*"

It will search for any proccess that its name starts with mail.

In Windows sorting running processes can also be done using command line.

Using the command prompt window, by typing "tasklist" the command will show all running process or services.

Depends on your environment and running processes working on the background, it will either show more or less output.

To sort the output, it needs to pipe tasklist output to another command which is "findstr.exe".

Type this command below on the command prompt window to sort the output.

tasklist | findstr /b "c"

It will sort the tasklist output for any running processes that starts with letter "c", like chrome.exe cmd.exe, csrss.exe etc.

If need to be specific or more granular filtering then type like:

tasklist | findstr /b "chr"

It will search for processes that begin with "chr".

To search for processes that ends with "me" type this command:

tasklist | findstr /r "me\>"

/r option in findstr will treat the string as regex or a regular expression search criteria.


So to search for any service that has a capital letter of "F", type:

tasklist | findstr /r "[*F]"

Sample output:

C:\>tasklist | findstr /r "[*F]"
HPFSService.exe                936 Services                   0      1,756 K
FileZilla Server.exe          2072 Services                   0      2,504 K
UNCFATDMS.exe                 4932 Console                    1      4,292 K
FXMeterReader.exe             6896 Console                    1     16,272 K
WUDFHost.exe                  8436 Services                   0      6,404 K

So if you need to practice regex, I guess sorting the output in Windows command line will be a good start.

It’s a simple way to do task via command line. It can be done of course using a graphical interface but command line helps a lot in automating process or working in multiple computers or servers.



Hope it helps..thanks for reading.

Notepad++ convert multiple lines to a single line and vice versa

Notepad++ is an awesome text editing tool, it can accept regex to process the text data. If the data is in a “.csv” format or comma separated values which is basically just a text file that can either be opened using a text editor, excel or even word. Notepad++ can process the contents of the file using regex. Example if the data has multiple rows or lines, and what is needed is to convert the whole lines of data into a single line. Notepad++ can easily do it using regex. However, if the data is on a single line and it needs to be converted into multiple lines or rows then regex can also be used for this case. Here’s an example on how to convert multiple rows or lines into a single line. Example data: Multiple rows, just a sample data.

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.

How to check office version from command line

Version The command line option will tell you where’s the path located; the result will also tell whether office is 32-bit, 64-bit and of course the version of the office as well. Here’s the command that will check the office version and which program directory the file is located which will tell whether it’s 32-bit or 64-bit. Command to search for Excel.exe: DIR C:\ /s excel.exe | find   /i "Directory of"  Above command assumes that program files is on  C: drive. Sample Outpu
