Rename the files in all the directories and sub-directories

Hi all,

I have more than 12000 files in 46 different directories and each directory has 2 sub-directories named “dat” or “gridded”. Dat sub-directories have files with extension “jpg.dat” and gridded sub-directories have files with extension “.jpg”.

I need to rename all the files (some parts to be replaced or removed and most of the parts to be rearranged) in all the directories and sundirectories.

Code:

Example name of the files:  
 Old names:

 (an example file from gridded subdirectories)
 gridded_yihF-b3861-DNA433-c1-384-20110301-Tp32-CmKan-Sel2-384-MMS-32C-set1-plate1.jpg 

 (an example file from dat subdirectories)
 yihF-b3861-DNA433-c1-384-20110301-Tp32-CmKan-Sel2-384-MMS-32C-set1-plate1.jpg.dat 

 New names:

 tom_dm-MMS_yihF-b3861_1_[1-4]_DNA433-20110301.jpg

 tom_dm-MMS_yihF-b3861_1_[1-4]_DNA433-20110301.jpg.dat

In the new name, words come in this order with these changes:

(1) “gridded” needs to be replaced with “tom” (in all the files from all the gridded subdirectories).
(2) “MMS” needs to come just after “tom” and it can also be “RM” instead of “MMS”
(3) “yihF-b3861” word will be different in every file
(4) “plate1” will be replaced with “1”. It can be “plate2” which needs to be replaced by “2”
(5) “set1” needs to be replaced with “[1-4]”. It can be set2, set3 or set4 and needs to be changed [2-4], [3-4] or [4-4] respectively.
(6) “ DNA433-c1-384-20110301” part will different in each file. It needs to be renamed to “ DNA433-20110301” but the “c1-384” which needs to be removed, is same in every file.
(7) File extensions “.jpg” or “.jpg.dat” remains the same.

Remaining part of the old name (i. e. -Tp32-CmKan-Sel2-384-) will be left out or deleted.

Thanks in advance. I appreciate your time.

systemd-tmpfiles

SYSTEMD-TMPFILES(8)						 systemd-tmpfiles					       SYSTEMD-TMPFILES(8)

NAME

       systemd-tmpfiles - Creates, deletes and cleans up volatile and temporary files and directories.

SYNOPSIS

       systemd-tmpfiles [OPTIONS...] [CONFIGURATION FILE...]

DESCRIPTION

       systemd-tmpfiles creates, deletes and cleans up volatile and temporary files and directories, based on the configuration from
       /etc/tmpfiles.d/. See tmpfiles.d(5) for more details on these files.

       If invoked with no arguments applies all directives from all configuration files in /etc/tmpfiles.d/*.conf. If one or more absolute file
       names are passed on the command line only the directives in these files are applied.

OPTIONS

       The following options are understood:

       --create
	   If this option is passed all files and directories marked with f, F, d, D in the configuration files are created. Files and directories
	   marked with z, Z have their ownership, access mode and security labels set.

       --clean
	   If this option is passed all files and directories with an age parameter configured will be cleaned up.

       --remove
	   If this option is passed all files and directories marked with r, R in the configuration files are removed.

       --prefix=PATH
	   Only apply rules that apply to paths with the specified prefix.

       --help
	   Prints a short help text and exits.

       It is possible to combine --create, --clean, and --remove in one invocation. For example, during boot the following command line is
       executed to ensure that all temporary and volatile directories are removed and created according to the configuration file:

	   systemd-tmpfiles --remove --create

EXIT STATUS

       On success 0 is returned, a non-zero failure code otherwise.
