There could be 'n' number of modules (referred as M) and those modules may
have 'n' no.of number of lectures (referred as L).

Now the requirement is to remove the modules from the filenames and have
only lectures in consecutive numerical order

If the directory has files names like this,

M1L1.mp4
M1L2.mp4
M1L3.mp4
M2L1.mp4
M2L2.mp4
M2L3.mp4
M2L4.mp4
M3L1.mp4
M3L2.mp4

Then, the resulting file list should be as below (were M followed by 'n'
value can be removed)

L1.mp4
L2.mp4
L3.mp4
L4.mp4 (here M2L1 should automatically get renamed to L4)
L5.mp4
L6.mp4
L7.mp4
L8.mp4 (here M3L1 again should automatically get renamed to L8)
L9.mp4

Although I have not been successful in my attempts to block ads at router
level, you can try flashing openwrt / gargoyle on your router which have
router level blocking of ads (based on blocking lists). HTH

New requirements! This is not what you mentioned in your initial
e-mail (where it was M1L01.mp4, M1L02.mp4 etc).

Yet again, new requirements!

I'd suggest you spend some time learning a scripting language, like
Ruby, and hack the existing script to suit your needs.

[Ilugc] [Help] Renaming files through bash shell scripts

2015-10-28 Thread Baskar Selvaraj 
Dear all,

I am looking for a simplified solution for renaming files through shell scripts.

I need the file names in continuous numerical order, i.e. from
M?L01.mp4 to M?L30.mp4

So, the file

M2L01.mp4 should be renamed to M2L11.mp4 and
M3L01.mp4 should be renamed to M3L21.mp4

M1L01.mp4
M1L02.mp4
M1L03.mp4
M1L04.mp4
M1L05.mp4
M1L06.mp4
M1L07.mp4
M1L08.mp4
M1L09.mp4
M1L10.mp4
* M2L01.mp4
M2L02.mp4
M2L03.mp4
M2L04.mp4
M2L05.mp4
M2L06.mp4
M2L07.mp4
M2L08.mp4
M2L09.mp4
M2L10.mp4
* M3L01.mp4
M3L02.mp4
M3L03.mp4
M3L04.mp4
M3L05.mp4
M3L06.mp4
M3L07.mp4
M3L08.mp4
M3L09.mp4
M3L10.mp4

Any help would be appreciated.

Sorry for my mistake.  What I mentioned in the initial e-mail was
correct.  It was M1L01.mp4 and M1L02.mp4 only.

M1L10.mp4 can be renamed to M1L00.mp4? Here is a quickly hacked up Ruby script:

=== test.rb ===

#!/usr/bin/env ruby

Dir.glob("*.mp4").each do |f|
  new_f = f.dup
  new_f[3] = (f[1].to_i - 1).to_s

  File.rename(f, new_f)
end

=== END ===

Hi,

Thanks for the script

The scripts works, but the results were different, if the value after L is < 10.

input:

M1L01.mp4
M1L02.mp4
M1L03.mp4
M1L04.mp4
M1L05.mp4
M2L01.mp4
M2L02.mp4
M2L03.mp4
M2L04.mp4
M2L05.mp4
M3L01.mp4
M3L02.mp4
M3L03.mp4
M3L04.mp4
M3L05.mp4

Output:

M1L01.mp4
M1L02.mp4
M1L03.mp4
M1L04.mp4
M1L05.mp4
M2L11.mp4
M2L12.mp4
M2L13.mp4
M2L14.mp4
M2L15.mp4
M3L21.mp4
M3L22.mp4
M3L23.mp4
M3L24.mp4
M3L25.mp4

That is the question I had asked in my previous reply. What should be
the expected behavior in such a case?
