delims | Generate RegExp for delimiters , to be used with templates | Runtime Evironment library

I have a batch file which uses a For /F loop to find all files with a specific (cadence backup uses for backup) setup.

For /F "delims=" %%A in ( 'Dir /B/S "*,*" ^| findstr ",[0-9][0-9]*$" ' ) Do Del "%%A"

and this works for this special setup (This is a special search for an unusual file name format of ABCDE.ZYX,1).

How do I reuse the findstr to find all .bak files as a second search string?

Separate question:

How does this line ( 'Dir /B/S "*,*" ^| findstr ",[0-9][0-9]*$" ' ) work? What is it doing? Please explain the functions and attributes.

I got this very wierd and unexplainable issue that boggles my mind for quite some time. Each time I run into this issue and I cannot figure out what is wrong since it is the same as it is for the other variables.

I know that there is probably some forum page wedged between the thousands of pages related to this where I could find my answer, however I cannot find that one in a thousand page.

So I am working on a script to run a filter for lines through and it is working fine except for this one stupid and stubbern variable that gives me the error message.

So when I run the following from my Bat-File called Test.bat (to keep names short) it gives me the error message following after.

How to delete a file with zero byte created accidentally with name "Call" ?

I'm facing with this issue that i couldn't figure it out until now ?

I tried with command Del but no chance.

I have a text file of data that I want to extract a couple values from specific locations on specific lines.

I recently wrote the code below on a batch file:

I have my array definition setup as such (trimmed down for example purposes):

I would like to execute a ping and, after evaluating the output, return a single line like "0 - check_ping rta=1 loss=0".

0 and 1 being extracted from the ping, of course.

I came this far:

I have to compress some folders every month that always start with the number of the referenced month followed by a -.

For example:

April: folder is 04- ??????
May: folder is 05- ???????

I just know the first part of the folder name. The rest of the folder name is always different.

I´m stuck here:

I have to use sc.exe to log the state of a few services to a text file.

I cannot use an external text, or ini file to list my windows services.

So whilst the following works:
