stat -c %y vs.exe | awk '{printf $1 "\n"}'

I found awk one of the most useful tools (almost like grep or sed).
awk treats the input line as a (database) record containing fields, using (by default) the space character as the field separator (but a different field separator can be specified in the command).
Then you can refer to any field of the line using its index ($1, $2, $3, etc.)
stat -c %y vs.exe | awk '{printf $1 ":" $3 "\n"}'
will print the first and the third fields on each line, putting ":" between the fields.
stat -c %y vs.exe | awk '{printf $1 ":" $3 }'

Extract NT Backup Files in Linux Using mtftar

If you would like to extract the contents of an NT backup (.bkf) file in Linux, mtftar is a utility that translates a Microsoft Tape Format (MTF) stream into the tar format. You can pick up mtftar from the authors site at http://gpl.internetconnection.net.

To get started, download the source code and compile.

$ wget http://gpl.internetconnection.net/files/mtftar.tar.gz
$ tar zxfv mtftar.tar.gz
$ cd mtftar
$ make
$ sudo cp mtftar /usr/bin/
- or -
$ su -c "cp mtftar /usr/bin/"

Using this utility is straight forward, as shown in the following example.
