extraction of multiple extensions of a file path name ...

[martin]

I have a newbie question about extracting extensions of file names;
bascially I have ful path name to some files with no, single, or
multiple extensinos, for example:

/dir1/dir2/.../dirN/filename.ext1.ext2.ext3

The extensions coud be anything, I just used ext1, ext2, so on.

I like to extraxt two things:

1- all the extensions up to the last one , in this case

ext1.ext2 (without .ex3)

Now if some of the interim extensions are numerical, I like to skip
them and get all the extensions exclusing the n umerical ones.


2- How can I extract the full pathname up to but not including last
extension, i.e. to get:
/dir1/dir2/.../dirN/filename.ext1.ext2

Thanks. Martin

Where is your code, and what didn't work?

probably .ext3 ?

What is your definition of an extension? Does it always start with a dot,
but does not contain a dot in itself? If so,

Let $filename contain your full path and file, then
$filename=~s/\.[^.]+$/;

will contain your new filename stripped off last extension and dot.

You forgot the last '/'

$filename=~s/\.[^.]+$//;
