Examples of filenames:
Code:
mRefresh_2018-06-28_003015.x
mRefresh_2018-06-28_221609.tar
mRefresh_2018-06-29_003058.tar
mRefresh_2018-06-29_003058.x
mRefresh_2018-06-29_220654.tar
mRefresh_2018-06-30_003043.tar
mRefresh_2018-07-01_222747.tar
mRefresh_2018-07-02_003030.tar

So, based on this list, I want the name of the last 4 files.

Code:
ls --version
ls (GNU coreutils) 8.12

Assuming (1) that there are other files in that directory but you are only interested in those that start with mRefresh; and (2) that the timestamp in the filename is the one you should be relying on:
Code:
ls -r mRefresh_* | sed '/\.x$/,$ d'

The files will be in reverse order, I'm afraid, but you can fix that if necessary by adding | tac to the pipeline.

virt-tar-out(1) 					      Virtualization Support						   virt-tar-out(1)

NAME
virt-tar-out - Pack a virtual machine disk image directory into a tarball. SYNOPSIS
virt-tar-out -a disk.img /dir files.tar virt-tar-out -d domain /dir files.tar virt-tar-out -d domain /dir - | gzip --best > files.tar.gz DESCRIPTION
"virt-tar-out" packs a virtual machine disk image directory into a tarball. The first parameter is the absolute path of the virtual machine directory. The second parameter is the tar file to write. Use "-" to write to standard output. EXAMPLES
Download the home directories from a guest: virt-tar-out -d MyGuest /home - | gzip --best > homes.tar.gz JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "tar-out" command. For anything more complex than a trivial copy, you are probably better off using guestfish directly. OPTIONS
Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options. SEE ALSO
