Script to list the contents of the latest archive?

Hi,

I am looking to write a script that will:

Get the latest Archive from a list
List the contents of the tar.gz
Print the name, size, and date of modification

I have:

Code:

gunzip -c ~/backups/PROJECTNAME_2013-02-28-16:27:27.tar.gz | tar -tvf -

Which gives me:

r--r-- ubuntu/ubuntu 5 2013-02-19 03:15 file0
-rw-r--r-- ubuntu/ubuntu 0 2013-02-28 16:47 fil1
-rwxr-xr-x ubuntu/ubuntu 795 2013-02-19 01:51 fil2
-rwxr-xr-x ubuntu/ubuntu 643 2011-11-20 14:13 fil3

But I want to sort this by last modification date:

Code:

gunzip -c ~/backups/PROJECTNAME_2013-02-28-16:27:27.tar.gz | tar -tvf - | sort -n

gives me:

-rw-r--r-- ubuntu/ubuntu 0 2013-02-28 16:47 fil1
-rw-r--r-- ubuntu/ubuntu 5 2013-02-19 03:15 fil0
-rwxr-xr-x ubuntu/ubuntu 643 2011-11-20 14:13 fil3
-rwxr-xr-x ubuntu/ubuntu 795 2013-02-19 01:51 fil2

Any ideas? to get order right:

name, size, and date of modification

You have to specify the field to be sorted out, using the -k option:

Code:

sort -k4n

Moreover, using GNU tar you don't need to uncompress the archive. Therefore you will end up with something like this:

Code:

tar tvf ~/backups/PROJECTNAME_2013-02-28-16:27:27.tar.gz | sort -k4n | cut -d' ' -f6-,3,4

Hope this helps.
