If you need to run scripts on specific weeks on a UNIX machine, then there is a easy way to determine this.
As I always have a tendency to forget the special variables used in shell scripts, I am going to document down the variables here.
At work, I have a couple of shell scripts to perform LDAP queries. Initially the scripts were hard-coded with the login credentials of a read-only user. But as the scripts were enhanced to handle LDAP query updates, I realised that it was not a good idea anymore to hard-code the username and password as I was just inviting trouble. And the scripts will be a big NO during system audit.
I have some shell scripts that will perform certain actions only on a weekend (Saturday or Sunday). There are two ways to solve the “is it a weekend” logic.
Solaris does not ship with the GNU tar and by default, the tar command in Solaris does not allow you to create gzip or bzip2 files, but only pure tarballs. You will need to create a tar file first and then compress the tarball with the gzip command.
I have been looking for a tool to encrypt
Ki values (into
eKi) using AES encryption.
Ki is a 128-bit value used in authenticating the SIMs on the mobile network.
To perform disk usage monitoring of users on a UNIX system, you will, first of all, need to determine the home directories of the users. You might ask, “Aren’t all the user home directories found under /home?”. Well, typically yes, but it’s not always true.
