[SOLVED] Linux career

Hi Mara,

Thank you for the advice.

Yes, I did setup a server at home already, with DHCP and web server.
I also have SAMBA and NFS configured, and also learned how to do port forwarding.

It's hard to volunteer right now as I am also working full time.

Thanks again,
Denny

You may ask someone to do security testing for you or just look around in the system to find out what you can do differently. You can also volounteer as a part-time admin for a school, local group etc. They always need admins and you can get your first experience this way.

(The Author once claimed PERL stood for "Pathologically Eclectic Rubbish Lister" due to the power it had handling text: we THINK he was kidding.) Python is the only newer scripting language that comes close to it for general utility and power. I prefer to use both of them, although seldom at the same time.

If you become a strong BASH coder, that makes you a power to be considered. If you add PERL, you become a solution master. Every additional power tool you master makes you more desirable as a candidate.

Is Perl easier to learn than Python?

Well, Perl isn't OO by default, which I believe Python is... (I'm not a Python user)

You can do OO in Perl and some modules are written that way, but the Descriptions/examples in CPAN https://metacpan.org/ are generally very good.
Personally I'm not OO myself, but I can still use those modules.

I managed to read the Python book by O'Riley and did the exercises online. It's been a while so I've forgotten most of it:-

Thanks for explaining about Perl.

Learning Perl looks good here:

http://learn.perl.org/

It's not clear whether you are looking for an opening in an IT company or in the Linux Administrator position in a non IT company.

The difference is that in an IT company you are likely to be part of a bigger team and with people to tell you what to learn and how to do things in Linux. OTOH in a non IT company, the employer may expect a level of experience and an ability to do many things independently from day 1.

IMHO, you need to focus on trying to understand the openings in your geographical area, the type of processes they have and how you can understand the processes.

OK

If you are interested in Perl, and like books, then "Learning Perl" is easy to follow, then I highly recommend "The Perl Cookbook" ..

Perl has OO by default. It's just...different. But, there are modules such as Moose or Moo that make OO much easier.

In general, I'd say yes, but there is a lot of good training material for python at the moment so it is feasible to learn both and then learn when to use either one.

However, a big reason to use perl is that is is easier, more flexible, and more powerful specifically in regards to handling text: Log files, except systemd log files, are text. So is a lot of other stuff like HTTP communication and various other protocols and even configuration files. Anything in JSON or XML is text, and so on. So you'll find it used a lot as well as find a lot of use for it yourself.

Perl is also rather high performance, if you write it well, and I've even read recent anecdotes where for certain text-related tasks it is faster than C.

Thanks for the details and information.
