Multi rename: how to Regex change to Upper/Lowercase?

[arbacia]

I am trying to rename a lot of files using Multi-Rename Tool and regex. I want to change some parts of the filename to lowercase.

Example:

• I want Aaa - 1993 - Bbb Ccc to be Aaa - 1993 - Bbb ccc

Search for:

Code: Select all

(.+) (.+)

Replace with:

Code: Select all

$1 $2

How I can set $2 to be lower case? Is it possible to set some of the matches to lower/uppercase individually? Similar to [N] or [L][N] but to individual regex matches. Something like [L]$2 doesn't work :S

I hope I made myself clear LOL. Thanks!

The regex-case-syntax would be:

Changing case in the 'Replace' box of regular expressions rule
Special character          Description
\u                                Converts the next character to uppercase.
\l                                 Converts the next character to lowercase.
\U                                Converts all characters to uppercase.
\L                                Converts all characters to lowercase.


But that is not supported with TC.



You could use Siren Renamer, though:


Siren is a freeware file renaming program - portable, flexible, powerfully, with preview, perl regex, meta data extraction,...
No installation needed, unzip and run. Siren stores it settings into an INI-file, not in the Registry.
If it's looking tricky, it's easy to rename with Siren. Press the F1-key while you are in Siren to read more about.

For a "use-with-TC" how-to see http://scarabee-software.net/forum/viewtopic.php?id=76



The expression for your issue would be

%b( s/(.+) (.+)/$1 \L$2/ ).%e

Explanation:
%b() > work on the base name
s/// > perl regex style
.%e > original extension

In the file name mask you can include both original name and name in lowercase. Then use regular expressions to get the right part from these strings.

Code: Select all

File name mask: [N]\[L][N][n]

Search for:   (.* ).*\\.* (.*)|\\.*
Replace with: $1$2

RegEx   checked

[E]     not checked
Subst   not checked 

Note:
Nowadays the multi rename tool can auto create folders and move files to sub folders, so it might be better to use a different character (or string) than "". That way, if you make a mistake, files will not be moved to sub folders.

This is not part of a Regular Expression scheme, it's program specific.
Even in Perl we'd have to use uc and lc.
RegEx is just about finding strings, but it's up to the program
how subgroups are referenced and if any other string manipulations are possible.

I agree with the solution from white, since you can't use any other special characters in the RegEx replace box than $<num>.
