Subject: Re: why i can't find my ruby ?

You may try these 3 commands and report the result:

$ which ruby
$ ls -l `which ruby`
$ ls -l `which ruby | sed -e 's/ruby//'` | grep irb

In my case, the result is:

$ which ruby
/usr/bin/ruby
$ ls -l `which ruby`
lrwxrwxrwx 1 root root 43 2010-05-10 14:47 /usr/bin/ruby ->
/opt/ruby-enterprise-1.8.7-2010.01/bin/ruby
$ ls -l `which ruby | sed -e 's/ruby//'` | grep irb
lrwxrwxrwx 1 root   root         42 2010-05-10 14:48 irb ->
/opt/ruby-enterprise-1.8.7-2010.01/bin/irb
-rwxr-xr-x 1 root   root        376 2010-03-19 18:45 irb1.8
lrwxrwxrwx 1 root   root          6 2010-03-31 17:00 irb-ORIG -> irb1.8


What it does is:

* use 'which' to find where you have ruby installed
* list the details about ruby (e.g. a symlink)
* search that same directory for the 'irb' command

That may give a hint where your ruby and irb are installed.

HTH,

Peter
