rich's questions

I need to rename approx. 70,000 files. For example: From sb_606_HBO_DPM_0089000 to sb_606_dpm_0089000 etc.

The number range goes from 0089000 to 0163022. It's only the first part of the name that needs to change. all the files are in a single directory, and are numbered sequentially (an image sequence). The numbers must remain unchanged.

When I try this in bash it grizzles at me that the 'Argument list is too long'.

Edit:

I first tried renaming a single file with mv:

mv sb_606_HBO_DPM_0089000.dpx sb_606_dpm_0089000.dpx

Then I tried renaming a range (I learned here last week how to move a load of files, so I thought the same syntax might work for renaming the files...). I think I tried the following (or something like it):

mv sb_606_HBO_DPM_0{089000..163023}.dpx sb_606_dpm_0{089000..163023}.dpx

In my parent directory I have 78,160 files.
File names are: sb_604_dpm_0089000.dpx, sb_604_0089001.dpx etc.

I want to move the files to 4 sub directories subdir1, subdir2, subdir3, subdir4. There must be exactly 20,000 files in each directory in sequential order.

Is it to possible to move a certain range of files from the parent directory to the sub-directories i.e., sb_604_dpm_0089000.dpx to sb_604_dpm_0108,999.dpx files to subdir1 sb_604_dpm_0109000.dpx to sb_604_dpm_0128,999.dpx files to subdir2 etc.

The final folder will only contain the remaining files after the first 60,000.

All of these should be done using a batch file, ideally being able to specify/check the range before the move proceeds. Is this possible?

In DOS I would probably be able to work this out for myself writing a batch file, but with Linux I'm a little lost... I'm not a programmer, I'm just a linux user looking for faster/better ways to do this rather than the GUI, so any help appreciated. Please keep it as simple as possible!

Thanks in advance!
