renameing numbered files

renameing numbered files

[Meino Christian Cramer]

Hi,

 in a directory there are a couple of file named:

 Example0092.txt
 Example0093.txt
 Example0094.txt
 Example0095.txt
 Example0096.txt
 Example0097.txt
 Example0098.txt
 Example0099.txt
 Example0100.txt
 Example0101.txt
 Example0102.txt

 which I want to rename to:

 Example0102.txt
 Example0103.txt
 Example0104.txt
 Example0105.txt
 Example0106.txt
 Example0107.txt
 Example0108.txt
 Example0109.txt
 Example0110.txt
 Example0111.txt
 Example0112.txt

 i.e. The first file of the new range should get the number of the
 file, which would be the next new one of the old range.
 The numbers themselves are only examples here, they could be of all
 range.

 How can I do this in a most zshy way?

 Thank you very much for any help in advance !

 Keep zshing!

autoload -U zmv
zmv -Qf 'Example(<->).txt(On)' 'Example${(l:4::0:)$(($1+10))}.txt'

That probably deserves some explanation:

Either the -Q option or (#qOn) is required because zmv turns off "bare"
glob qualifiers by default.

The -f option is required because the set of source names overlaps with
the set of destination names (0102 is in both).

Sorting (On) forces the higher-numbered files to be renamed first,
otherwise 0092 --> 0102 --> 0112 will result (the original 0102 would
be lost).  If the leading zeroes weren't there, you'd need (nOn) for
numeric sorting.

Using $(($1+10)) discards leading zeroes, so (l:4::0:) puts them back.

I suggest playing around with "zmv -n" a bit to be sure it's going to
do what you intended.

  Yes, of course! Magic always deserves some explanations !

Thanks a lot Bart!
I will experiment with that...

Have a nice weekend!
