[Level 1] Switch between user and role in OpenSolaris.

As we know, when we add a new user during OpenSolaris installation wizards, then installer will switch "root" from user to role. And we cannot login the system with role "root".
How can we switch root from user to role, after that, how can we switch back?
You can use the command below:

0. how to verify root is user or role:
[case 1: root is role]
# cat /etc/user_attr | grep ^root;
root::::type=role;auths=solaris.*,solaris.grant;profiles=All;lock_after_retries=no;clearance=admin_high;min_label=admin_low
[case 2: root is user]
# cat /etc/user_attr | grep ^root;
root::::type=normal;auths=solaris.*,solaris.grant;profiles=All;lock_after_retries=no;clearance=admin_high;min_label=admin_low

1. Change root from role to user:
# rolemod -K type=normal root;

2. Change root from user to role:
# usermod -K type=role root;

Wish this helps.

[Level 1] Rar tool for Solaris.

Sometimes we will got a rar compressed file from our friends, but there is no default tool in OpenSolaris to decompress the rar filess. We can got a Solaris Intel version from rarlab . The steps as the following: 1. down load the rar tools from rarlab. http://www.rarlab.com/rar_add.htm 2. uncompressed the source. # gunzip ./unrar-sol-intel.gz 3. move it to the location you used to. # mv /unrar-sol-intel.gz /usr/bin/unrar 4. try to decomprss # unrar x ./test.rar Wish this helps. regards, Stanley Huang

[Level 2] iif in Python

If you want to implement iif in Python, please refer to the following sample code: #!/bin/env python def iif(b): return 'It\'s True' if b else 'It\'s False' print iif(True) print iif(False) And the following sample, guess what will you get! #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % 'Ture' if b else 'False' Result: $ ./iif.py b: Ture False The second result is "False", not "b: False". Why??? Because the prededence of string concatenation is higher than if. Therefore you need to use () to make it correct. #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % ('Ture' if b else 'False') Wish this helps. regards, Stanley Huang
