Exodus<\/strong>\u00a0is a simple yet useful program for easily and securely copying\u00a0Linux ELF<\/strong>\u00a0binaries from one system to another. For example, if you have\u00a0htop (Linux Process Monitoring Tool)<\/a>\u00a0installed on your desktop machine, but not installed on your remote Linux server, exodus gives a way to copy\/install the\u00a0htop<\/strong>\u00a0binary from the desktop machine to the remote server.<\/p>\n

It bundles all of the binary\u2019s dependencies, compiling a statically linked wrapper for the executable that invokes the relocated linker directly, and installing the bundle in the\u00a0~\/.exodus\/<\/code>\u00a0directory, on the remote system.<\/p>\n

You can see it in action here.<\/p>\n

\"Exodus<\/center>Exodus really comes in handy in two critical cases:\u00a01)<\/strong>\u00a0if you do not have root access on a machine and\/or\u00a02)<\/strong>\u00a0if the package you want to use is not available for the Linux distribution you are running on another machine.<\/p>\n

Install Exodus in Linux Systems<\/h3>\n

You can install\u00a0exodus<\/strong>\u00a0using\u00a0Python PIP package manager<\/a>, as follows. The command below will perform a user specific installation (only for the account you have logged on with).<\/p>\n

$ sudo apt install python-pip                [Install PIP On Debian\/Ubuntu]\r\n$ sudo yum install epel-release python-pip   [Install PIP On CentOS\/RHEL]\r\n$ sudo dnf install python-pip\t             [Install PIP On Fedora]\r\n$ pip install --user exodus-bundler          [Install Exodus in Linux] \r\n<\/pre>\n
Next, add the directory\u00a0~\/.local\/bin\/<\/code>\u00a0to your\u00a0PATH<\/strong>\u00a0variable in your\u00a0~\/.bashrc<\/code>\u00a0file, in order to run the exodus executable like any other system command.<\/p>\n
export PATH=\"~\/.local\/bin\/:${PATH}\"\r\n<\/pre>\n
\n
\"Add<\/a><\/p>\n
Add Exodus Path in Bashrc<\/p>\n<\/div>\n
Save and close the file. Then open another terminal window to start using exodus.<\/p>\n
Note<\/strong>: It is also highly recommended that you\u00a0install gcc<\/a>\u00a0and one of either\u00a0musl libc<\/strong>\u00a0or\u00a0diet libc<\/strong>\u00a0(C libraries used to compile small statically linked launchers for the bundled applications), on the machine where you\u2019ll be packaging binaries.<\/p>\n
Use Exodus to Copy Local Binary To a Remote Linux System<\/h3>\n
Once you have installed\u00a0exodus<\/strong>, you can copy a local binary (htop tool) to a remote machine by simply running the following command.<\/p>\n
$ exodus htop | ssh tecmint@server3\r\n<\/pre>\n
\n
\"Exodus<\/a><\/p>\n
Exodus Copy Htop Binaries to Remote Linux<\/p>\n<\/div>\n
Then login to the remote machine, and add the directory\u00a0\/home\/tecmint\/.exodus\/bin<\/code>\u00a0to your\u00a0PATH<\/strong>\u00a0in your\u00a0~\/.bashrc<\/code>\u00a0file, in order to run the\u00a0htop<\/strong>\u00a0like any other system command.<\/p>\n
export PATH=\"~\/.exodus\/bin:${PATH}\"\r\n<\/pre>\n
\n
\"Add<\/a><\/p>\n
Add Exodus Path in Remote Linux Bashrc<\/p>\n<\/div>\n
Save and close the file, then\u00a0source<\/strong>\u00a0it as follows, for the changes to take effect.<\/p>\n
$ source ~\/.bashrc\r\n<\/pre>\n
Now you should be able to run\u00a0htop<\/strong>\u00a0on your remote Linux machine.<\/p>\n
$ htop\r\n<\/pre>\n
If you have two or more binaries with the same name (for example, more than one version of\u00a0htop<\/strong>\u00a0installed on your system, one\u00a0\/usr\/bin\/htop<\/code>\u00a0and another\u00a0\/usr\/local\/bin\/htop<\/code>), you can copy and install them in parallel with the\u00a0-r<\/code>\u00a0flag, it enables for assigning of aliases for each binary on the remote machine.<\/p>\n
The following command will install the two\u00a0htop<\/strong>\u00a0versions in parallel with\u00a0\/usr\/bin\/grep<\/strong>\u00a0called\u00a0htop-1<\/code>\u00a0and\u00a0\/usr\/local\/bin\/htop<\/strong>\u00a0called\u00a0htop-2<\/code>\u00a0as shown.<\/p>\n
$ exodus -r htop-1 -r htop-2 \/usr\/bin\/htop \/usr\/local\/bin\/htop | ssh tecmint@server3\r\n<\/pre>\n
Attention<\/strong>: Exodus has a number of limitations and it may fail to work with non-ELF binaries, incompatible CPU architectures, incompatible Glibc and kernel versions, driver dependent libraries, pro-grammatically loaded libraries and non-library dependencies.<\/p>\n
For more information, see the exodus help page.<\/p>\n
$ exodus -h           \r\n<\/pre>\n
