Linux – Make binary executable available for all user

executablelinuxsoftware installation

How to make a binary file available for all linux(Ubuntu) user.
eg:
When we install the golang using apt install golang-go the go executable is available for all user.

Where will they add the configuration for that.

I checked it in global level /etc/environment, /etc/profile, /etc/init.d/ i couldn't find any reference there !

Distributor ID: Ubuntu
Description:    Ubuntu 16.04.4 LTS
Release:        16.04
Codename:       xenial

Its not even in ~/.bashrc or ~/.profile; even-though these files are user specific.

Since the apt install gives the old version of go; i need to manually install the latest version of go and make it available for all the user.

When executing a command without specifying a path, the system searches for the executable in locations specified in PATH environmental variable. Paths in PATH-variable are searched in order and first found executable is used.

/usr/local/bin is a reasonable place to install your own executables as it is possibly already included in the distribution provided default PATH and it should not conflict with system's package manager. If the directory structure of your program makes placing files in /usr/local/ inconvinient, another reasonable location to place the files is in /opt under its own subdirectory (and additionally creating symbolic links/launch scripts in /usr/local/bin).

Create a file named (say) anaconda.sh in /etc/profile.d/ with the contents:

PATH=/opt/anaconda3/bin:$PATH

The trailing ".sh" is important, as that is the syntax that /etc/profile uses to search for files to include. Bash will read /etc/profile at login. If you want a current shell/terminal to pick up the change, just run . /etc/profile.d/anaconda.sh.

If you encounter situations where a non-interactive shell needs it, you're left with ~/.bashrc (unless the calling environment uses --rcfile to override that behavior).

apt – Rollback All apt-get Packages to Maximum Available Under sources.list

You don't tell how you tried pinning and how it failed, but the solution is pinning indeed. If you've already removed all sources you aren't interested in, create /etc/apt/preferences.d/back.pref with the following contents:

Package: *
Pin: release o=*
Pin-Priority: 1001

After this, apt-get dist-upgrade will up/downgrade all packages to your current sources.

If it doesn't work out, check the output of apt-cache policy and apt-cache policy OFFENDING-PACKAGE for hints.
