I have an Operating system image of size 2.5G.
I have a device with a limited size. Thus I was looking for the best possible solution for providing the compression.
Below are the commands and results of their compression:
1.tar with gzip:
tar c Os.img | gzip --best > Os.tar.gz
This command returned an image of 1.3G.
2.Xz only:
xz -z -v -k Os.img
This command returned an image of 1021M.
3.Xz with -9:
xz -z -v -9 -k Os.img
This command returned an image of 950M.
4.tar with Xz and -9:
tar cv Os.img | xz -9 -k > Os.tar.xz
This command returned an image of 950M.
5.tar with Xz -9 and -e:
xz -z -v -9 -k -e Os.img
This command returned an image of 949M.
6.lrzip:
lrzip -z -v Os.img
This command returned an image of 729M.
Is there any other possible best solution or command line tool ( preferable ) for the compression?

Usingtarwill not make much difference as it's a single file. Thetarutility will not compress the file differently from what you would do if you first created the tar archive and then compressed it, in two steps.

What portability do you need? The methods with highest compression need more RAM also for extraction (decompression).
