Find the path of a java classes and jar file for inclusion in the classpath.
Posted by Julio Sanchez in Java, QuickTip on September 17, 2010
Before beginning I must thank my colleague Miguel Angel Jimenez (Instructor JAVA) to create a simple but practical example of Java code that demonstrates the usefulness of this script. Some time ago I asked this script to speed up searches for java classes inside the jar files, including information on the path to the desired [...]

how to create an install a package for solaris 10

how to perform operations with decimals in shell script
Posted by Julio Sanchez in QuickTip on September 14, 2010
As bourne shell (sh) does not know how to work with numbers, is required to invoke unix expr to work with integers. Both korn shell (ksh) and Bourne Again Shell (bash) include arithmetic operations but only to work with integers. To work with decimal numbers in arithmetic operations can be invoked from our script to [...]
avoid lock of the root account
Posted by Julio Sanchez in Networking/Security, QuickTip on September 13, 2010
In the last post we saw how to enable account lockout after multiple failed login attempts, but if the account is locked is the root can be a big problem. The idea is that blocking is not applied to the root account and it launched the following command: root@solaris # usermod -K “lock_after_retries=no” root easy, [...]

ShellScript: Interesting command this ‘tput’

For this worthless activities, I found ‘tput’. tput is a quite simple command which comes with a basic Solaris installation. I reads termcap database [...]
delegate the administration of the ssh service to a regular user
Posted by Julio Sanchez in Solaris on September 9, 2010
As only root can run svcadm command, with RBAC could create a profile with this command and assigned to a regular user, but could work on any service and just want to give it control of a particular service, the ssh. So this is not a valid solution. To solve this problem we have the [...]
