Thanks for your views Anisha.
Will start new threads for different topics from now on.
I did search Google with the keywords you mentioned, and found them helpful.

Thanks to all for help.

Yah, our zVM, VMS guys and such still use REXX quite heavily; in zLinux
we don't, really. There's ONE rexx script us guys use, but don't have the
privilege to edit (zVM boys own it).

I didn't say it isn't far spread, or that knowing it is not a good
thing; it just isn't a programming language, and you listed it as one.

Just trying to avoid confusion of terms.

1. Get some basic & moderate understanding of C
You seem to have gotten strong and opposite opinions on that one. I'm in the camp that strongly says don't. C is for programmers, not system administrators. It wouldn't hurt to know C, but it would hurt to spend the time needed to learn C when that time should have been spent on something you really need.

Quote:
2. Become master in Perl, Python as they are used in scripting.
Learning some about one of those wouldn't be as much of a side track as learning C. But it isn't the core of what you need.

Quote:
3. Learn bash-scripting as much as possible.
And then learn it some more!

Bash is a programming language. It is far more than just a command language. A Linux sys admin needs to know a significant amount of programming, and the language is bash.

Most of the programs you use will be written in C. But almost all the programs that you need to dig into the source code to understand are written in bash. Similarly, programs you will need to modify will be almost all in bash. Programs you may need to write as a sys admin can be written in bash.

Quote:
4. Learn tools like sed, awk, grep (I have no idea what awk is, but will look up on net).
And a whole lot more, but since I'm not really qualified to be a Linux sys admin, I couldn't give you a good list.

c and ruby are easy to learn you can get paid a lot for c i don't know ruby anymore but it is easy web administrating is good to know even though it is not programming. this is just my opinion.

No, C is not easy to learn. C has relatively few reserved words, it seems that one can learn it quite fast. But there is much more to it, think of pointers, and look what can be done with pointers, for example programming lists or trees, or other complex structures.

For Ruby you are right, one can quickly learn to use it for solutions of simple problems. But one can also write objectoriented code or functional code with Ruby and this is not as easy as writing a simple script for system administration.

Do you mean to say that in "Linux system Administration" tasks, "C" is preferred over "BASH Scripts"?

If you want your career in "Sys Admin", I believe bash/ksh scripting, and some tcl/perl enough for you. C is for the programers.

This is my post but I need to add a development now.. RHCE is no longer the first step for Sys Admin. Red Hat has replaced RHCT with RHCSA and made it mandatory to pass RHCSA exam before one can apply for RHCE.

For a detailed explanation follow http://www.redhat.com/certification/rhcsa/
