Rename files with regex

Question

I have several files in a direcotry such as :

BUSCO_Canis_lupus_BUSCO_v3_451441870_exon_probs.pbl
BUSCO_Canis_lupus_BUSCO_v3_45144182_metapars.cgp.cfg
BUSCO_Canis_lupus_BUSCO_v3_451441E0_weightmatrix.txt
BUSCO_Canis_lupus_BUSCO_v3_451441D0_parameters.cfg

and I would like to rename these file by removing the BUSCO_ part at the begenning and the _BUSCO_v3_Number_ part in the middle to get :

Canis_lupus_exon_probs.pbl
Canis_lupus_metapars.cgp.cfg
Canis_lupus_weightmatrix.txt
Canis_lupus_parameters.cfg

I know how to use sed and mv but not how to combine both.

With perl rename:

rename -n 's/(?:^BUSCO_|_BUSCO_v3_\d+)//g' *BUSCO*

Remove -n switch when the output looks good

Sure, it's the purpose of the command – Gilles Quénot Jun 29 '20 at 13:37
What is the output of `rename` ? Is it contains `perlexpr` ? – Gilles Quénot Jun 29 '20 at 13:38
When I tap rename in my terminal I get : rename ```-bash: rename: command not found``` – chippycentra Jun 29 '20 at 13:39
Which OS/distro/version ? – Gilles Quénot Jun 29 '20 at 13:39
it is Debian version – chippycentra Jun 29 '20 at 13:41
So `apt install rename` It's a _must have_ in the tool box – Gilles Quénot Jun 29 '20 at 13:41
Okay I have it, it workd but it still let the numbers ex : ``'Canis_lupus451441870_exon_probs.pbl' ``` and it does not rename it says : ```ancien_file_name would be renamed to new file name``` – chippycentra Jun 29 '20 at 13:53
My post is 3 line long, can you eventually read all ? – Gilles Quénot Jun 29 '20 at 13:53
oups sorry ... ok for the -n, so there is still the remaining number issue – chippycentra Jun 29 '20 at 13:55
