With respect to Regex, this expression is common to all six file names:  E[0-9]{1,2}

All what I want to do to the six files is to append ")" to my regular expression, so that "E08" becomes equal to "E08)", "E09" becomes equal to "E09)", "E14" becomes equal to "E14)", and so forth.  How do I do this in the renamer?

Try

Code Select Expand

E[0-9]{1,2}[\)]?
The part between [] defines a character class containing only the closing bracket, escaped by a backslash. The question mark allows 0 or 1 brackets.

Thorsten, that expression isn't working for me.  But, where should I enter that expression?

Maybe I misunderstood your question.
As you talk about the renamer, I assume you want to rename some files? Could you post an example of the original file names (as in your first post), but together with the expected resulting file names? This would be helpful.
If, for example, you want to rename
Test S01E15 SomeText.jpg
to
Test S01E15) SomeText.jpg,
you can use a "Original Filename" step followed with a "Replace Text":

Code Select Expand


Replace: E([0-9]{1,2})
With:E\1)

"Regular Expression" must be checkboxed, of course. The \1 references the first Capture Group (the part that is grabbed by the RegExp between ( and ) in the Replace expression). So, an E followed by one or to digits is replaced by E and these one or two digits, followed by the closing bracket.

Thorsten, "E\1)" did the trick!  What I was ignorant of was the use of \# in the "With:" field, for the purpose of updating "S01E##" with "S01E##)", in the "Replace:" field.  Thanks!

I always use the Regex Calculator online to learn about regex expressions... https://regex101.com -  helps explain each step and what it is doing.

Darius,
glad to hear that it works for you now!

Andy,
thanks for the link! This site looks very helpful. I am always happy if one of my RegExp works as expected - mostly after a lot of trial & error...

You bet ... years ago I bought RegexMagic... https://www.regexmagic.com - used it to learn how to build expressions.  Now, there are websites that do similar things but regexmagic (or its big brother - RegexBuddy) is quite good still!  Enjoy!
