I would like to rename files that have the following format:
somethingblabla15T06:58_31+0000somethingblabla.bla
THe new name should be
somethingblabla15T06:58:31+0000somethingblabla.bla
So the _
within the numbers should be replaced with :
.
I would like to do this with the perl based rename command line tool.
I thought this would be a part of the regex:
's/[0-9](_)[0-9]/:'
I can't get it to work. I think this should also be escaped or so.
