Cleanup old refs in Ruby Version Manager (RVM)

Question

I need to free disk space on my local machine, which is almost allocated into my Ruby Version Manager (RVM) dir.

Now, it seems I got just one ruby version ( 1.9.2p136 ) :

lsoave@ubuntu:~/rails/github/gitwatcher$ ruby -v
ruby 1.9.2p136 (2010-12-25 revision 30365) [i686-linux]
lsoave@ubuntu:~/rails/github/gitwatcher$ 

lsoave@ubuntu:~/rails/github/gitwatcher$ rvm list
rvm rubies
=> ruby-1.9.2-p136 [ i386 ] 
lsoave@ubuntu:~/rails/github/gitwatcher$

lsoave@ubuntu:~/rails/github/gitwatcher$ which ruby
/home/lsoave/.rvm/rubies/ruby-1.9.2-p136/bin/ruby
lsoave@ubuntu:~/rails/github/gitwatcher$ 

but my RVM dir, have many others unrelated dirs/versions :

lsoave@ubuntu:~/rails/github/gitwatcher$ ls -la ~/.rvm/gems
total 72

drwxr-xr-x  2 lsoave lsoave 4096 2011-02-10 19:04 system
lsoave@ubuntu:~/rails/github/gitwatcher$

is it save to remove all dirs remaining with just "ruby-1.9.2-p136" and "ruby-1.9.2-p136@global" dirs (ruby-1.9.2-p136@greendog* are old and "rvm system" return nothing) ? Will I use "rm" command, or are there RVM embodied commands to cleanup a better way ? Is it possible cleanup the cache dir ?

Thanks in advance. luca

Answer 1

I suppose rvm cleanup could do the trick.

Other than that I don't see any reason that deleting the actual gem directories inside RVM if they aren't associated with RVM any more.

If the matching entry doesn't exist in environments then it is safe to delete the accompanying gem dir. As nothing else points to it that RVM would be able to use.

Answer 2

... it turn out that some of the previous, not used refs, were just gemsets:

rvm gemset list
lsoave@ubuntu:~$ rvm gemset list

gemsets for ruby-1.9.2-p136 (found in /home/lsoave/.rvm/gems/ruby-1.9.2-p136)
global
greendog
greendog2
greendog99

lsoave@ubuntu:~$

which I removed like following:

lsoave@ubuntu:~$ rvm gemset delete greendog99
Are you SURE you wish to remove the entire gemset directory 'greendog99' (/home/lsoave/.rvm/gems/ruby-1.9.2-p136@greendog99)?
(anything other than 'yes' will cancel) > yes
lsoave@ubuntu:~$ rvm gemset delete greendog2
Are you SURE you wish to remove the entire gemset directory 'greendog2' (/home/lsoave/.rvm/gems/ruby-1.9.2-p136@greendog2)?
(anything other than 'yes' will cancel) > yes
lsoave@ubuntu:~$ rvm gemset delete greendog
Are you SURE you wish to remove the entire gemset directory 'greendog' (/home/lsoave/.rvm/gems/ruby-1.9.2-p136@greendog)?
(anything other than 'yes' will cancel) > yes
lsoave@ubuntu:~$

than I made a backup of one of the old 'lib' ( just in case ... ):

lsoave@ubuntu:~/.rvm/gems$ tar zcvf ruby-1.8.7-p302.gz ./ruby-1.8.7-p302

and removed the relative directory as a previous comment talk, with stuartc:

lsoave@ubuntu:~/.rvm/gems$ rm -rf ./ruby-1.8.7-p302

now back to work.

I'll wait a couple of days, looking for everything is right ...
