listing directories only from tar file

Recently I faced one requirement where i had to list only certain level of directories with "tar -tvf" (or) "jar -tvf" output.

Here is my sample tar file. where I need to list only two levels of files/directories.

bash-3.2# tar -tvf content.tar
drwxr-xr-x   0/0        0 Dec 29 16:58 2015 direcotry2/
drwxr-xr-x   0/0        0 Dec 29 16:58 2015 direcotry2/directory2a/
drwxr-xr-x   0/0        0 Dec 29 17:00 2015 direcotry2/directory2a/directory2a_media/
-rw-r--r--   0/0       33 Dec 29 17:01 2015 direcotry2/directory2a/directory2a_media/home.html
drwxr-xr-x   0/0        0 Dec 29 16:58 2015 direcotry2/directory2a/directory2a_business/
drwxr-xr-x   0/0        0 Dec 29 16:58 2015 direcotry2/directory2b/
drwxr-xr-x   0/0        0 Dec 29 16:58 2015 direcotry2/directory2c/
drwxr-xr-x   0/0        0 Dec 29 16:56 2015 directory1/
drwxr-xr-x   0/0        0 Dec 29 16:57 2015 directory1/directory1_a/
drwxr-xr-x   0/0        0 Dec 29 16:57 2015 directory1/directory1_a/directory1a_media/
-rw-r--r--   0/0       33 Dec 29 17:00 2015 directory1/directory1_a/directory1a_media/media.html
-rw-r--r--   0/0       33 Dec 29 17:00 2015 directory1/directory1_a/directory1a_media/home.html
drwxr-xr-x   0/0        0 Dec 29 16:57 2015 directory1/directory1_a/directory1a_press/
-rw-r--r--   0/0        0 Dec 29 16:57 2015 directory1/directory1_a/directory1a_press/press.html
-rw-r--r--   0/0        0 Dec 29 16:57 2015 directory1/directory1_a/directory1a_press/welcome.html
drwxr-xr-x   0/0        0 Dec 29 16:55 2015 directory3/

The "awk" way:

Listing the parent directories alone:

bash-3.2# tar -tvf content.tar |awk -F/ '{if(NF==3) print}'
drwxr-xr-x   0/0        0 Dec 29 16:58 2015 direcotry2/
drwxr-xr-x   0/0        0 Dec 29 16:56 2015 directory1/
drwxr-xr-x   0/0        0 Dec 29 16:55 2015 directory3/

Listing the Parent directories with its sub - directories(or) files

bash-3.2# tar -tvf content.tar |awk -F/ '{if(NF==4) print}'
drwxr-xr-x   0/0        0 Dec 29 16:58 2015 direcotry2/directory2a/
drwxr-xr-x   0/0        0 Dec 29 16:58 2015 direcotry2/directory2b/
drwxr-xr-x   0/0        0 Dec 29 16:58 2015 direcotry2/directory2c/
drwxr-xr-x   0/0        0 Dec 29 16:57 2015 directory1/directory1_a/

Another level down

bash-3.2# tar -tvf content.tar |awk -F/ '{if(NF==5) print}'
drwxr-xr-x   0/0        0 Dec 29 17:00 2015 direcotry2/directory2a/directory2a_media/
-rw-r--r--   0/0       33 Dec 29 17:01 2015 direcotry2/directory2a/directory2a_media/home.html
drwxr-xr-x   0/0        0 Dec 29 16:58 2015 direcotry2/directory2a/directory2a_business/
drwxr-xr-x   0/0        0 Dec 29 16:57 2015 directory1/directory1_a/directory1a_media/
-rw-r--r--   0/0       33 Dec 29 17:00 2015 directory1/directory1_a/directory1a_media/media.html
-rw-r--r--   0/0       33 Dec 29 17:00 2015 directory1/directory1_a/directory1a_media/home.html
drwxr-xr-x   0/0        0 Dec 29 16:57 2015 directory1/directory1_a/directory1a_press/
-rw-r--r--   0/0        0 Dec 29 16:57 2015 directory1/directory1_a/directory1a_press/press.html
-rw-r--r--   0/0        0 Dec 29 16:57 2015 directory1/directory1_a/directory1a_press/welcome.html

Just change the "NF" value according to your requirement.

you can use this in case of  "jar -tvf" as well

Hope it helps. Comments welcome.
