executing a command from a ruby script

[greg]

Hi All,

I want to execute a command from a script e.g. var=`ls -l`, however I
don't want to specify the file until I have done some things in the
ruby script, so I need something like var=`ls -l $file`. However, this
is not working. Could anyone help me out. I would really appreciate
it!

Thanks,
Greg

var=`ls -l #{file}`

Not me. Ruby is.

Be aware of the security risk:

file = "; rm -rf *"
var=`ls -l #{file}`
