Rename multiple files with bash for loop, mv, and sed -


My goal 'img_MM-DD-YY_XX.jpg' to rename the form of files folder 'newyears_YYYY' - MM-DD_XXX.jpg 'by using sed to substitute each file name again and based on character positions. Unfortunately I do not seem to be working on status-based swaps.

For example s /. [4 \} [0-9] [0-9] / Trying to change MM with YY

Here's my attempt (Ignore for _XX part): [0- 9] [0-9] / P> 

  for file name in images * * new name = $ (echo $ filename | sed / s. {4 \} [0- 9] [0-9] /. \ {10 \} [0-9] [0-9] /; s /. \ {7 \} [0-9] [0-9] /. \ 4 \} [0-9] [0-9] /; s /. \ {10 \} [0-9] [0- 9] /. \ {7 \} [0-9] [0- 9] /; c / Yng_ / Nevyears_20 / ') mv $ filename $ Nunme Done   
 Any ideas how can I fix this?   
 
   $ echo 'img_11-22-14_XX.jpg' | Sed -r 's / [^ _] * _ ([0- 9] {2}) - ([0- 9] {2}) - ([0- 9] {2}) / NewIer_20 \ 3- \ 1- \ 2 / 'newyears_2014-11-22_XX.jpg   
 Any sound above the thing and includes locates the first after the date of 6 points. It replaces the initial part with the  newyears _  and reproduces the date from 20-yy-mm-dd to mm-dd-yay.  
 Two-digit MM, DD or standard value matched with  ([0-9] {2}) . The parentheses indicate that  sed should capture the value for later use. The output side of the replacement is  _20 \ 3- \ 1- \ 2 . It restores the underlined and adds a  20  to the front of the year. The year was the third occupation value, so it has been marked as  \ 3 . Similarly, months ago was assumed possession, so it is marked  \ 1  and on the second day it is because it is  \ 2 .  
 Blackslashes to eliminate some, I used the  -r  option to invite extended regular expressions. If you are on Mac or other non-GNU systems, use  sed -r  instead of  sed -E . Otherwise, use:  
  sed 's / [^ _] * _ \ ([0-9] \ {2 \} \) - \ ([0- 9] \ {2 \} \) - \ ([0- 9] \ {2 \} \) / newyears_20 \ 3- \ 1- \ 2 / '

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
