Need help with the rename command in Linux












2















I have several files with these names:



file1, A.ext  
file1, The.ext


I need to change there names as



A file1.ext  
The file1.ext


That is I need to move the article from the end to the beginning erasing the comma. How would I do that?



I have looked into rename command but I have no experience with perl regex, I came up with this ridiculous command which doesn't work, I'm leaving it for showing my hopelessness:



rename 's/(?<=[A-Z a-z s]*),sA//' *

          You would need to have:



          rename -n 's/^([^,]*),s*(.*).ext$/$2 $1.ext/' *



          • This ^([^,]*), matches everything but a comma until a first comma seen from the begging of the files name.


          • This s*(.*).ext$ matches zero-or-more whitespaces followed by anything and ends with .ext.


          • The $2 and $1 is back-references to the (.*) and ([^,]*) respectively.



          will do rename as following:



          rename(a single file,.ext,  a single file.ext)
          rename(a single file, some thing.ext, some thing a single file.ext)
          rename(file1, A.ext, A file1.ext)
          rename(file1, the.ext, the file1.ext)


          P,s: remove -n to do rename on files which is used for testing.

          You would need to have:



          rename -n 's/^([^,]*),s*(.*).ext$/$2 $1.ext/' *



          • This ^([^,]*), matches everything but a comma until a first comma seen from the begging of the files name.


          • This s*(.*).ext$ matches zero-or-more whitespaces followed by anything and ends with .ext.


          • The $2 and $1 is back-references to the (.*) and ([^,]*) respectively.



          will do rename as following:



          rename(a single file,.ext,  a single file.ext)
          rename(a single file, some thing.ext, some thing a single file.ext)
          rename(file1, A.ext, A file1.ext)
          rename(file1, the.ext, the file1.ext)


          P,s: remove -n to do rename on files which is used for testing.
