I have a backup script which is creating two files:
a) db_mywebsite_2018-01-10_00-25.sql.gz
b) mywebsite1_2018-01-10_00-01.tar.gz
I'm looking for a Linux command with regex to rename both files to match db_mywebsite.sql.gz mywebsite1.tar.gz
The regex command need to remove date (20XX-XX-XX_XX-XX) from file names (each day it will be different).
Thanks for your help!

You must have a look at rename command. It accepts regex patterns.
Usage:
rename [options] [Perl regex search/replace expression] [files]
From man rename:
-v, --verbose
Verbose: print names of files successfully renamed.
-n, --no-act
No Action: show what files would have been renamed.
EDIT:
The appropriate regex for your file names is _\d{4}-\d{2}-\d{2}_\d{2}-\d{2}. So you can find this in file names and then replace it with nothing as below:
rename -v -n 's/_\d{4}-\d{2}-\d{2}_\d{2}-\d{2}//' *.sql.gz
I didn't test above command, but it must work.
