Not a number

Hello,

I was hoping that doing

rm file123\D.txt

would delete all files of the following format: file123.txt, file123a.txt, file123b.txt. But instead it complains that file123D.txt could not be found. What am I doing wrong?
Many thanks in advance for you help.

You need

rm file123*.txt

But be careful that will remove all files that start file 123+anything.txt in the current working directory.
If you know there's just one character after "123" and before ".txt" you could use

 rm file123?.txt

Thank you for replying.

I need to delete files that named like : file123.txt, file123A.txt, file123B.txt, file123C.txt, and so on. But I don't want to delete file1234.txt, file1234A.txt, file1234B.txt. Please advice.

I'm not sure if you can do that in one go. You can try this

rm file123.txt && rm file123[A-Z].txt

This would leave "file1234.txt" or "file1235.txt" untouched.
If you google "bash scripts" or specifically "bash wildcards", there's plenty of help online.

That worked. I did not think of it that way. Thank you again.
