[MacRuby-devel] Admin privileges / Authorization Framework

[Steen Klingberg]

Jeff,

to run commands with admin rights without password, you can do it the unix
way. Run "sudo visudo" and add something like this:

steen ALL=(ALL) NOPASSWD: /usr/bin/du

then from ruby you can run the command without needing a password:

steen$ macirb
irb(main):001:0> spawn 'sudo du -s -m /Users/rebecka'
=> 15088
irb(main):002:0> 394 /Users/rebecka

/Steen
