How to test ruby-shadow

ruby-shadow-test.rb

[root@host ~]# irb
irb(main):001:0> require "/usr/lib64/ruby/site_ruby/1.8/powerpc64-linux/shadow.so"   #varies by platform - check 'rpm -ql ruby-shadow' for real location.
=> true
irb(main):004:0> Shadow::Passwd.getspent()
=> #<struct Struct::PasswdEntry sp_namp="root", sp_pwdp="$1$s9SM/aIM$ATv5Gcjkd2b/G/rkddVTq0", sp_lstchg=15095, sp_min=0, sp_max=99999, sp_warn=7, sp_inact=-1, sp_expire=-1, sp_flag=-1>

(execute getspent() repeatedly, should give a new user entry each time.

irb(main):009:0> Shadow::Passwd.setspent()
=> nil
irb(main):010:0> Shadow::Passwd.getspent()
=> #<struct Struct::PasswdEntry sp_namp="root", sp_pwdp="$1$redhat$9yxjZID8FYVlQzHGhasqW/", sp_lstchg=15097, sp_min=0, sp_max=99999, sp_warn=7, sp_inact=-1, sp_expire=-1, sp_flag=-1>

(running setspent should reset back to the first entry, which you can get again with getspent)

irb(main):005:0> Shadow::Passwd.getspnam("root")
=> #<struct Struct::PasswdEntry sp_namp="root", sp_pwdp="$1$s9SM/aIM$ATv5Gcjkd2b/G/rkddVTq0", sp_lstchg=15095, sp_min=0, sp_max=99999, sp_warn=7, sp_inact=-1, s

(gives you a particular user entry)
