Unzip subdirectory contents of zip file to /tmp?

Question

As part of a scripted software installation on Xenial Xerus I have a zipped archive called 'test.zip' that contains, among other files, some files in a sub-directory called samples:

andrew@athens:~/Desktop$ unzip -l test.zip 
Archive:  test.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
        0  2016-09-15 13:29   materials/

---------                     -------
    60072                     9 files
andrew@athens:~/Desktop$ 

Using Xenial Xerus's commandline unzip utility how do I extract the contents only of samples, decompressing them to /tmp?

Solution

The command would be to extract with folder names (default behavior):

unzip test.zip samples/* -d /tmp

without folder names (extracting files only contained in samples folder):

unzip -j test.zip samples/* -d /tmp

From man unzip:

   -j     junk paths.  The archive's directory structure is not recreated;
          all files are deposited in the extraction directory (by default,
          the current one).

Hope this helps!

what does -j do?

@Anwar Added from the manpage what -j does.

OP wanted to extract the contents of samples, there might be some directory they don't want to lose.

@Anwar With folder names would keep the directory structure.
