Hi there, please take some time to use an meaningful subject so i can see that you are a human!

Please provide first a valid pattern-rule for all of your files.

Taken your example the rule would be:
* Take first word and move it after the third word (OR, right before the first dash)
* add a comma after the second word
This can be done with an RegEx command.

If your file names not always have three parts/words before the first dash,
think about an other rule, or separate your files into groups and rename them with different rules.

I'm human... except I couldn't find a nice and clear subject

When I go to RegEX I see Match en replace....
Could you please provide an example how it should be done??? I'm far from an expert

Thanks

[Stefan]

An RegEx only works correct for the pattern of file names it was indented for!

FROM:
Anja de Crom - Villa Volta.epub

TO:
de Crom, Anja - Villa Volta.epub


DO:
RegEx(1)
Match: (.+) (.+) (.+)( -.+)
Repla: \2 \3, \1\4


Explanation of this very simple expression:
. ==> match one-occurrence-of-any-sign
+ ==> match one-or-more of the expression right before (one-any-sign in our case)
(...) ==> put the expression into (...) to store what is matched as backreferences (can be accessed by \1 for the first group, \2 for second,...)

So i match three times one-or-more-of-any-sign, separated by an space, and then an space-dash-space followed by one-or-more-of-any-sign

In the replacement i just rearrange that was is matched by the RegEx and stored in the (...)-groups. Adding an comma myself.

Again: this RegEx is only valid for file names like:
Word Space Word Space Word Space Dash Space one-or-more-of-any-sign
like
Anja de Crom - Villa Volta.epub

[JEPEDEWE]

it doesn't seem to be correct...
I get
m, Anja de Cro -
sorry

[Stefan]

m, Anja de Cro -

Then you didn't have typed the regex correctly.

[JEPEDEWE]

OK, it works.. thnaks
Now I wanted to change what you suggested so it would work with names like
Allan Folsom - Dag Van Bekentenis.epub
and rename into
Folsom, Allan - Dag Van Bekentenis.epub
but I can't find the right combination

Thanks again

[Stefan]

Same as above. Only difference is, there are only two words now.

FROM:
Allan Folsom - Dag Van Bekentenis.epub
TO:
Folsom, Allan - Dag Van Bekentenis.epub

DO:
RegEx(1)
Match: "(.+) (.+)( - .+)"
Repla: "\2, \1\3"

Note: the " " quotes are only for clarify, don't write them too.

I would like to see
Waanzin - Anne Allee.epub
as
Anne Alle - Waanzin.epub

So I wrote:
RegEx(1)
Match: (+.-) ( - .+)
Repla: \2,\1

Nothing happens.... Just when I thought I understood the system....

[Stefan]

You have only one dash in your filename, so you can match it only one time too.

Read an RegEx tutorial first so you will understood what all this meta chars means.

I took a look at "perlrecharclass" but found it too complicated for my level of computing
this is what I tried
(+.-)(.+)
\2\1
but... nog good..
I must have all characters before "-" and all characters after "-" and then swap them..

Thanks for your kind help
JP

[Stefan]

I must have all characters before "-" and all characters after "-" and then swap them..

You can find this request and the solution several times in this forum,...
particular if the questioner have used an better subject then always "how to???":

(.+) - (.+)
\2 - \1
