1) start the puppet master.

check process running on linux.

----------------------'
1) puppet will tell state of user.
cmd : puppet resource user root.
output :
user { 'root':
ensure => 'present',
comment => 'root',
gid => '0',
home => '/root',
password => '!!!!!!',
password_max_age => '99999',
password_min_age => '0',
shell => '/bin/bash',
uid => '12',
}
2) change state of shell command from bash to sh.
a) create a mnifest of the root user.
cmd : sudo puppet resource user root > root.pp
b) save and open the manifest file.
user { 'root':
ensure => 'present',
comment => 'root',
gid => '0',
home => '/root',
password => '!!!!!!',
password_max_age => '99999',
password_min_age => '0',
shell => '/bin/sh',
uid => '12',
}
c) apply the manifest
puppet apply root.pp
d) now check state of the user again.
cmd : puppet resource user root.
user { 'root':
ensure => 'present',
comment => 'root',
gid => '0',
home => '/root',
password => '!!!!!!',
password_max_age => '99999',
password_min_age => '0',
shell => '/bin/sh',
uid => '12',
}
3) now if we want to just simulate and dont want to change the state.
cmd :
a) vim root.pp
user { 'root':
.
.
shell => '/bin/bash',
.
}
b) puppet apply root.pp --noop (it show what all the changes might happen to the state if we use it)
