How to remove Ruby from the server?

Hello!
How to completely remove Ruby from the server?

# which ruby
/usr/local/bin/ruby

# whereis ruby
ruby: /usr/bin/ruby1.8 /usr/bin/ruby /usr/lib/ruby /usr/bin/X11/ruby1.8 /usr/bin/X11/ruby /usr/local/bin/ruby /usr/local/lib/ruby /usr/share/man/man1/ruby.1.gz

It was not installed via apt-get. Just delete the ruby ​​directory (/usr/local/bin/ruby) and restart the server?

Answer 1

dpkg -l | grep ruby
​​And carefully remove the packages that are found.

Answer 2

the uninstall procedure is always the opposite of the installation procedure.
if you messed up something like hell, or want to experiment - it's better to use the installation of ruby, rails and gems via rbenv, in your home directory without affecting the system

Answer 3

With this command, you can see which Ruby is currently in use.

lsof -c ruby | grep 'ruby$'
ruby     940 deployer  txt    REG               0,36   127407  56362580 /home/deployer/.rvm/rubies/ruby-2.2.1/bin/ruby

If /usr/local/bin/ruby is not used, you can safely delete it.
If you haven't deleted the ruby ​​source directory, look at the .installed.list file in it, you will see all the paths where you uploaded the files after make install.
This is a quick cleanup of files from .installed.list
but empty directories will remain, it is better to delete them manually

/usr/local/include/ruby-x.x.x/
/usr/local/lib/ruby
/usr/local/share/ri

More or less like this.
