General :: Perl Useful In System Administration And Application Development On UNIX?
Sep 11, 2010
It is just a general discussion on "How Can Perl Be Useful in System Administration and Application Development on UNIX and Linux Platforms"? I am doing pretty much well with Bash and PHP. In fact, I am learning and experimenting in depth in those two domains. The project that I am working for these days has several scripts which are written in Perl and Ksh. They interact with Ab Initio graphs and perform extensive jobs. Anyways, my current role doesn't require me to have knowledge of Perl but I don't see any harm in learning something new.
So, before I take it, I want to know how Perl can help me and what I can do with it as a UNIX / Linux System Administrator and Application Developer? I just looked at some of its keywords, functions, and commands. Perl Variables are identical to those of PHP. Conditional Statements, Loops, etc. are also much the same as found in any other computer languages. So, at first glance, I have got this feel that it wouldn't be much difficult for me to learn it. But what do you say? Do I really need Perl when I am focusing on PHP and Bash?
I have to set up my development environment under OEL 5.4. The internal directory structure is more or less fixed, the question is where to put the whole application tree in standard FHS for the development phase.For production, the system will be deployed on a server where data is kept with an Oracle 11g database. Development goes with JDeveloper which has its own internal application/project directory structure; however, I whould like to be independent from this. Unfortunately, by carefully studying the web for FHS, if I will adhere to it I only find ready-made packages to put under /opt, for example. No development aspects are mentioned. make some proposal, possibly with respect to best practices.
i am having a problem on Ubuntu 10.10. In system menu, there is no Administration or Preferences menu.Also, application menu does not show anything. I am using Ubuntu since 2 weeks and still not used to to the terminal commands for running applications and admin tools.

How can I install a minimal GUI interface, on a Ubuntu server? And more: Suse has a RUNLEVEL tool, to select application to be launched. What in Ubuntu? I need a GUI interface ONLY to use some useful administration tools, no other application, and need to charge the system as less as possible.
I installed a library to the /usr/local/ prefix in Linux using ./configure && make && make install. What environment variables do I need to set in order for the linker and compiler to search these new library and header paths?
I'd like to know some good resources, links, e-books to learn basic Linux system administration scripting. I know how to write very basic BASH shell scripts so I'm still at beginner level. There are so many docs out there that I'd like to narrow down people's opinion's on the best easy to understand resources that are available. Eventually I'd like to learn basic PERL as well.
fscheck is quite annoying, since it usually occurs when I reboot my system performing administration tasks. do I actually need fscheck if Im using the ext3 file system? if not how would I extend the period between checks or just turn it off altogether?
What are the directories and files in Unix file-system that has default user permission set. For eg. home directory of a user can't be seen by the other users on the system without his permission.

Generally you can set system clock using [URL]. However, it doesn't supply millisecond precision (it does have nanoseconds, but this isn't working on my system). Is there another way to set system clock, or will I need to write a C program to do it?
