┌──(highway㉿highway)-[/usr/lib/go/bin]
└─$ go
Command 'go' not found, but can be installed with:
sudo apt install gccgo-go
sudo apt install golang-go
what different between floder /usr/lib/go/bin and /usr/local/go?if there were not different what can i do to use go instead of cd /usr/lib/go/bin && ./go.

Answer 1

You need to append go's bin directory to your PATH environment variable. Add this line at the end of ~/.bashrc:
export PATH=$PATH:/usr/lib/go/bin

Answer 2

An alternative to #emilianolch solution is to create symlinks in /usr/local/bin. And you properly want all the binaries in /usr/lib/go/bin linked, so:
sudo ln -s /usr/lib/go/bin/* /usr/lib/bin/
Should work right away without restarting terminal.
PRO: Go binaries appear as they are like other distro. May work better with other tools like VS Code SSH Remote.
CON: Have to ln again if more Go tools are installed via apk in future. (Only new ones, not needed if reinstalling/upgrading existing ones)
