I am learning Shell Programming ..but the book I have is "Unix Shell Programming" and I know there are gonna be some differences, but in this case, Error Redirection is not working as wanted... Here's the script. i=a echo `i` 2>> err Can somebody point out the error? ..if there's any ..lol Also, I want to install "ksh" on SuSE. Just wanted to ask whether it is provided with the default installation..or is it present in the Cds..or do the Repositories offer them? I had added non-free reps in my SuSE Installation Sources, but I don't think I was able to find "ksh" in the list. PS: I have also included Packman. -- http://mckagan.googlepages.com

I know! But thats not the point. The problem is...that My 'echo' command will generate an error and that error should be redirected to a file called "err" . The problem is ...such redirection is not achieved due to some flaw in my code. On Sun, 15 Oct 2006, Duff Mckagan wrote:

Yes, because ls is not a bash built-in, but echo and time are. $ type -a time time is a shell keyword $ type -a echo echo is a shell builtin I believe stdout/stderr do not work properly for shell built-ins. Justin. On Sun, 15 Oct 2006, Duff Mckagan wrote:

For KSH, you could grab the RPM from http://rpmfind.net/ -- ksh has no odd-ball dependencies: $ ldd ksh linux-gate.so.1 => (0xffffe000) libdl.so.2 => /lib/tls/libdl.so.2 (0xb7ef9000) libm.so.6 => /lib/tls/libm.so.6 (0xb7ed4000) libc.so.6 => /lib/tls/libc.so.6 (0xb7da1000) /lib/ld-linux.so.2 (0xb7f14000) So you should be fine if you get one from rpmfind.net; however, I do not know of a specific repository for SuSE+KSH, sorry.

Yes. Notice that the ">>" means append to file, while ">" will create the file. Therefore, the "2>> err" translate as append error output to file "err".

Also, I want to install "ksh" on SuSE. Just wanted to ask whether it is provided with the default installation..or is it present in the Cds..or do the Repositories offer them? I had added non-free reps in my SuSE Installation Sources, but I don't think I was able to find "ksh" in the list.

PS: I have also included Packman.

Hummmm, it's on the dvd:

You will want either ksh-93 or pdksh, not both. You will find both on the cd sets as well as the dvd for 10.0. -- Until later, Geoffrey Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. - Benjamin Franklin

Can somebody point out the error? ..if there's any ..lol

If the reason you want ksh is because your book uses it, I'd recommend that you go and buy a book based on bash instead. bash is much more widely used on Linux, so it's more useful to learn that, IMHO. Cheers, Dave

No thats not the point...

The book is about 'Unix Shell Programming - Bourne, C and Korn Shells' But most of the commands related to Bourne should work on Bash.(not sure though). Also, they said that the Korn shell is their personal choice..and they believe its the best of all the three...I guess the book is a bit old..They never mentioned the Bash Shell...(cuz its wasn't Borne again :P - Bash - Bourne Again Shell... Its old..but yeah..its helping..:) Can anybody suggest any good author Books for Bash Scripting? -- http://mckagan.googlepages.com

That's true and also true to some extent about ksh.

There used to be religious wars about sh, csh and ksh. But time has moved on. IMHO, the question is whether you're likely to spend lots of time writing your own scripts from scratch, or whether you're likely to be reading other people's scripts and modifying them. In the first case, you get a free choice of shell language, but in the second case, you're most likely to be working with bash scripts.

The online docs are pretty good: ftp://ftp.cwru.edu/pub/bash/FAQ and especially: http://www.gnu.org/software/bash/manual/bashref.html.gz Check out the indexes at the end :) I haven't used any books about bash, but O'Reilly is usually a good place to start looking: http://promosearch.atomz.com/search/promosearch?query=bash&sp-q=bash&sp-a=sp1000a5a9&sp-f=ISO-8859-1&sp-t=general&sp-x-1=cat&sp-q-1=&sp-x-2=cat2&sp-q-2=&sp-c=25&sp-p=all&sp-k=Articles%7CBooks%7CConferences%7COther%7CWeblogs&c=&p= Perhaps somebody else can suggest a book from personal knowledge?

That's true. Bash is "Bourne-compatible".

The older Bourne shell is absolutely miserably compared to bash. Don't use it unless you must... remember COMMAND.COM under DOS 3.x? It's about the same, plus the addition of stream piping and background processes. But no command editing capabilities at all. Of the Unix admins i've known, particularly those who've worked a lot under Solaris, most tend to prefer ksh for two reasons: a) It's installed by default on most Solaris systems, whereas bash is not. b) It's supposedly got some features which are better for shell SCRIPTING (as opposed to interactive use) than bash. Not quite sure what those are, though. At the last company i worked at (a bank using tons of Solaris boxes), 99% of the scripts were written for ksh... and the other 1% were written by me. In the end, i managed to convert several of the admins to bash for interactive shell use, but i never did manage to convert any of them to bash for writing scripts. There was simply too much cultural momentum promoting ksh.

It doesn't matter, because the term Carriage Return is older than that. It comes from type writers. The carriage is the thing sitting on top of the machine, with the lever you pull to make it go back with a "ping". This is the original Carriage Return.

Actually, that "ping" was the end of line bell, that warned the typist to return the carriage, before hitting the end of the line.

Anyone here remember the original "Candid Camera"? There was one gag, where prospective secretaries were given a typing test and the carriage returned right off the typewriter and into the trash can. ;-)

As did many teleprinters (Teletype is a registered trademark). For example the Teletype Corp. Model 15 had a carriage much like one on a typewriter.
