5. So you can see 7zip is not in Ubuntu linux
-by default it does not get installed...
You can see the command to install
Sudo apt-get install p7zip-full
Sudo apt-get install p7zip will also work, full
Let’s do it..
So for Ubuntu the command is 7zr
In fedora it is 7za...
Actually, 7z has different commands
7zr is one of them
7za is anoth
7z is another
It is not and it should not be different based on Linux distribution if it
is the same software—though not impossible to be different...
6. Let’s try to install the full version..
7z
7za
7zr
7z
7za
7zr
7. Copy paste did not work...
It can be changed using virtual box
configuration changes whether to allow gust
to host clipboard sharing or not...
Anyway...
You can see the syntax by using man 7za
8. You can see one example command and related
explanations
Lzma is the algorithm name for 7zip
Mx=9 the most compression
One thing looks like the output size is more than input
The reason: my guess the files that I compressed is
almost empty
The output file usually will use some meta data inside the
zip file, that can increase the output file (size more than
original)
-guessing
Though you are supposed to get 30 to 50% compression using
7zip
9. Let’s see some compress software for Ubuntu
You will find similar for Fedora or other linux
Tar – the achieve command can also compress
along with archiving
You need to pass j or z
J is for bzip z is for gz
Just different algorithms and different levels of
compression
7z can be slower than others if you want more
compression mx=9, ultra compression level
11. You can use 7zip to compress your backups
Such as code and database of your projects
7zip does not come with Fedora or Ubuntu, I
mean does not get installed by default
Sometimes, it may not be part of the package
repo
For my case, it was part of package repository
So I did not have to download to install it
I had situations where I had to download rpm files for
the package and had to install it – for fedora...
12. So, just remember this
You may need to download the package source
or rpm installer and then install it
