Ive been playing around with Linux a little bit and have started to look into different shell types. I know BASH is the most basic, or that is in most distro. but is there any disadvantages of using a Korn shell instead?

I work for AT&T and our Windows-centric workgroup is being tasked with supporting an app running on RedHat. To help my coworkers, I'm building a Fedora 11 VM that we can play with to familiarize ourselves with the UNIX environment.
Because of corporate network policies in place, my VM can't get access to the Internet.
Since we're AT&T employees, we're naturally using the korn shell on the production system. I'd like to install the korn shell on my VM. However, it doesn't appear to be part of the base fedora repository.
Is the korn shell available for Fedora? If so, how would I copy it to shiny media, mount it on my VM, and install it?
Some may recall I recently gave up on bash, rather than give up my programming style.Surely I will have reason to return but that's another story. My little issue now:I am debugging a new [Korn] shell script. I have a function that performs a specialized match on a string and I see that I am able to call that function with no problem, with both of it parameters. The function does not do any print or echo command - it uses "return" for a TRUE (0) of FALSE (1), as is the shell exit code convention. Thus, I have the following test:
Code:
if [[ match_except_release ${PATH_DIR[$LC]} bin ]]

I have 4GB of RAM in my machine, and I am using 32Bit Ubuntu Lucid, I was wondering if there were any disadvantages of using the PAE mode version of the kernel, as that would allow me to use the whole of my memory instead of 2.9 GB.

View 4 Replies View RelatedI am a graduate student writing a dissertation in modern history. More than half of my computer work takes place on a word processor.I take notes, make outlines, and then write drafts of papers, chapters, presentations, etc. I regularly have to share these files with others who use operating systems other than Linux.I have just switched from OS X (after 5 years and half of using Mac) and I am still figuring out how to write my next dissertation chapter in Ubuntu.
There seems to be no consensus on what is or what are the best word processing softwares -- especially for academic writers -- in Ubuntu or Linux for that matter.I have read a number of posts on various forums and I find them either dated by several years or not dealing with the problems I am facing :
namely writing a serious, book-length academic work in the humanities and desiring to work with a user-friendly and fast word processor that would also be powerful enough to accomplish most or all academic tasks such as footnotes, style change, bibliography, accessibility, etc. There are people who suggest using LaTeX (LyX, Kile, etc.) but it seems to me that they're mostly based in the exact sciences and benefit from the math and science features that exist in LyX or another LaTeX editor. LaTeX is moreover not very accessible to those who do not know the LaTeX language or do not have an editor and work primarily with a word processor: meaning that when I share a LaTex document with my colleagues they have difficulty editing my work. See for instance this discussion which took place 5 years ago on this forum:
http://ubuntuforums.org/showthread.php?t=98120
I wonder if those of you who are in similar fields (i.e., humanities, social sciences, law, etc.)could chip in and talk about your experience as academic writers working primarily from a Linux (specifically Ubuntu) platform. What are the word processing applications you use to write your serious papers?What are the advantages and disadvantages of OpenOffice.org Word Processor, Kword, and AbiWord? How easy or difficult is it to share your documents with others who do not use Linux? In what format/s do you share your documents? Can others easily modify and edit your texts? Do you use LaTeX at all?Opinions may vary with respect to discipline,which word processor to use for writing their articles, dissertations, or books.
My own personal experience with OpenOffice.org has not been very positive. It's pretty slow and has problems with multiple language input. Switching from Nisus Writer Pro and Mellel (both OS X softwares), OpenOffice.org Word Processor seems also not very user-friendly. It seems to follow the design of MS Word (or what MS Word used to be) and feels above all *cluttered.* I am however trying to like it as I understand there's probably no other word processor better than OpenOffice.org in Ubuntu. Am I correct to assume this? I also downloaded Kword which in terms of interface and egronomic design seems quite nice. It is also a bit faster -- although I don't know how powerful Kword is at the moment and whether it can accomplish all that my academic work requires from a word processor. I have also read somewhere that AbiWord is really not all that powerful. It is meant to be a fast but "lean" word processor which would do basic things quickly.
Assume this array in Korn:
Code:
HOSTS[ home ]="163.164.165.166"
HOSTS[ work ]="122.123.124.125"

View 8 Replies View RelatedI have scowered the internet for the answer to this one. I need a script to rename multiple files to the same exact name, run a program on the file then do the same for the next file. We have a unix backend system that is expecting to load the file with the filename of cards.in So I will have files named card.2009xxx, like i said i will have around 4 or five of those. I want the script to rename card.2009xxx to cards.in, run our unix program on cards.in which inturn changes the file name and once complete i want the script to rename the next cards.2009 to "cards.in"Until there are no more left in the directory and the unix program has processed all the files. All of this is occurring in the same directory. I have written some scripts but they fail by moving for example cards.200901 to cards.in then immediately moving cards.200902 to cards.in and that is not good because it is overwriting valuable data
View 10 Replies View RelatedOne of this is Linux software.Installing programs from various distribution's package repositories leads to using out of date versions. From this point of view Windows users have an advantage. They always have latest releases.So, I want to ask a simple question: what disadvantages do I have when use "compile form source" methods of installing software. Also it would be interesting to know what method is prefered for you. Imagine, that you want to install nmap. Latest stable version is 5.50. apt-get offers 5.21. What would you do?

Is there some type of functional way to read things in the Python shell interpreter similar to less or more in the bash (and other) command line shells?
Example:

...
I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.

I was working on a shell and got some weird exceptions in my program.Just as a reference, I want to save all that is there on my shell to a text file. I do not just want the command history but also all the results that those commands produced at the shell.Is there some built-in utility to do this? I have kept the shell open for now, so that I can take the backup. Also, I am using xterm and it does not allow selecting all the way upto the top of the shell, so the ultimate way is to take the backup one screen at a time.
