I've little issues trying to change the name of several amount file names using rename command.

I have 1 main directoy, and so many others inside, after this, the whole content are .wav files.

/rec/101/101-27022018-01:00:09-M00.wav

I want to change the 'hour' of the file;

101-27022018-01:00:09-M00.wav

Using the same date as reference

101-27022018-01:00:09-M00.wav

I've tried something like this:

rename 's/27022018-01/27022018-08/' *.wav -v -n

The question is, what if I want to change the name of all those files inside of all those directories? How it would be?

If we have directory structure with two levels and there are not files within the first level:

$ tree /tmp/rec
/tmp/rec
├── 101
│   ├── 101-27022018-01:00:09-M00.wav
│   └── 101-27022018-01:00:09-M01.wav
├── 102
│   ├── 101-27022018-01:00:09-M00.wav
│   └── 101-27022018-01:00:09-M01.wav
└── 103
    ├── 101-27022018-01:00:09-M00.wav
    └── 101-27022018-01:00:09-M01.wav

$ rename -n 's/27022018-01/27022018-08/' /tmp/rec/*/*.wav

rename(/tmp/rec/101/101-27022018-01:00:09-M00.wav, /tmp/rec/101/101-27022018-08:00:09-M00.wav)
rename(/tmp/rec/101/101-27022018-01:00:09-M01.wav, /tmp/rec/101/101-27022018-08:00:09-M01.wav)
rename(/tmp/rec/102/101-27022018-01:00:09-M00.wav, /tmp/rec/102/101-27022018-08:00:09-M00.wav)
rename(/tmp/rec/102/101-27022018-01:00:09-M01.wav, /tmp/rec/102/101-27022018-08:00:09-M01.wav)
rename(/tmp/rec/103/101-27022018-01:00:09-M00.wav, /tmp/rec/103/101-27022018-08:00:09-M00.wav)
rename(/tmp/rec/103/101-27022018-01:00:09-M01.wav, /tmp/rec/103/101-27022018-08:00:09-M01.wav)

When the directory structure is more complex we can use the bash globstar option:

$ tree /tmp/rec
/tmp/rec
├── 101
│   ├── 00
│   │   └── 101-27022018-01:00:09-M00.wav
│   ├── 01
│   │   └── 101-27022018-01:00:09-M00.wav
│   ├── 101-27022018-01:00:09-M00.wav
│   └── 101-27022018-01:00:09-M01.wav
├── 102
│   ├── 00
│   │   └── 101-27022018-01:00:09-M00.wav

│   │   └── 101-27022018-01:00:09-M00.wav
│   ├── 101-27022018-01:00:09-M00.wav
│   └── 101-27022018-01:00:09-M01.wav
└── 103
    ├── 00
    │   └── 101-27022018-01:00:09-M00.wav
    ├── 01
    │   └── 101-27022018-01:00:09-M00.wav
    ├── 101-27022018-01:00:09-M00.wav
    └── 101-27022018-01:00:09-M01.wav

9 directories, 12 files

$ shopt -s globstar
$ rename -v 's/27022018-01/27022018-08/' /tmp/rec/**/*.wav

/tmp/rec/101/00/101-27022018-01:00:09-M00.wav renamed as /tmp/rec/101/00/101-27022018-08:00:09-M00.wav
