rush, the ruby shell

[Robert Citek]

Hello all,

Was wondering if anyone here has played with rush, the ruby shell:

I played with it. It is really nice for working with two connections,
like scp. I'm not sure if I would use it for day to day stuff.

Was this with ruby 1.8.* or 1.9? - Robert

Excellent, as I'm running 1.8.6 on Ubuntu 8.04:

$ ruby -v
ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux]

Will give rush a whirl.

I was hoping to use it to maybe have a more sane interface to some
system information. For example, I would like to know how many block
are being used on an ext3 filesystem. Does rush have a better
solution than this?

$ sudo tune2fs -l /dev/sda5 |
ruby -lane '
bc=$_.match(/(\d+)$/)[0].to_i if /^Block count:/ ;
fb=$_.match(/(\d+)$/)[0].to_i if /^Free blocks:/ ;
END {puts bc-fb}
'

maybe as an attribute of a filesystem object?
