...a GTK front end
I've been waiting long for this day!
Bash was my first shell and I used it exclusively for years. One day, I'd read enough about zsh to force myself to give it a try. Oh how I loved thee, bash, but I won't be going back.
Dewey, what part of this looks like authorities should be involved?
Hell, I didn't even know bash was still in active development. It was always just bash to me, not bash-x.y.z. But then I guess I wouldn't notice the difference, really.
Switch back to Slashdot's D1 system.
What are these, I wonder? Something along the lines of changing the prompt to always display [litigious@bastards]$, perhaps?
Real Daleks don't climb stairs - they level the building.
Someone tell me why I want this. The Usenet post doesn't seem to explain what's so exciting about it, besides a bunch of boring bug-fixes, and some esoteric-sounding syntax changes.
I don't need no instructions to know how to rock!!!!
Doesn't seem to be much changed given the version number increase. [[ =~ ]] can match regexes and it can do zsh style {1..3} expansions. Improved multibyte support too. There were bigger changes in some of the 2.0x updates.
I am looking at the title going a Linux bash headline on slashdot, now i must have been dreaming. But I am sure that i would not post that here, knowing i would loose all my karma in one stroke.
It's nice to see yet more contributions from Apple to the OSS community.
Several bug fixes for POSIX compliance came in from Apple; their assistance is appreciated.
It looks like Apple is giving back to the community, and to a fundamental tool.
To the parent: I'm in the same boat. I thought bash 3?? What is there to add?? Looks like multibyte char support (sorry, I'm are a dum Amer'kin).

Yeah, Bash 3.0 is great and all, but when are the bash people going to upgrade rbash? Man, I can't do anything with that shell!
Dopewars!
The reason the CLI was invented!
I seriously hope they've fixed that bag. Since a lot of GNU/LNUX distros don't even ship with a real sh, but symlink to bash. Some random linux bozo makes a #!/bin/sh script thinking it will be portable, but bash (at least 2.x does) forgets to switch off some features when invoked as /bin/sh, so in the end you write a non-portable script. And listen, linux people, /bin/bash is not standard!
Alfred, tired of fixing stupid scripts that assume the whole world has bash in /bin.
Looks like a nice Unicode-savvy release that should help with dealing with international languages at the command line. And yay to Apple for giving back (again). When will people finally accept that Apple is indeed helping out the OSS community through GCC, bash, and other tools...?
Kind of off-topic, but for speed purposes in scripts that have to run fast, I find nothing better or more convenient than Ash, especially on systems where
Does anyone know any history on this shell? Is it a clone of the original bourne shell or of bash? I can't seem to find anything useful on Google

I still use tcsh (not for shell scripts, just interactively), essentially for a single feature. If someone can tell me how to do this in bash, I might try it again.
If you type a partial command and then press alt-p or esc-p, tcsh pulls up the most recent command in the history that matches what you typed. Not in the "!partialcmd" sense of executing something that matches, but pulling it up for editing on the command line.
Is there a key (or way to get a key) that does that in bash or not?
There's been an interesting little problem caused for people like Gentoo with the updates in bash 3.0.

What is so hot about bash, e.g. compared to zsh?
Seriously, I'm not trying to start a flame war here. This is coming from a really long term zsh user because back when I was just starting unix and linux a fellow bearded unix guru told me something along the lines "go with zsh, it's the best" (thas was about -95). And I've never looked back, but now seing bash being the default shell in most distros I've began to wonder what's going on. Perhaps over the years bash overtook zsh or there are some hidden qualities in bash that I don't know about.
Anyone with some insight on _both_ shells would be greatly appreciated.

Gentoo's various scripts rely on the fact that /bin/sh is usually symlinked to /bin/bash. With 3.0, when invoked as /bin/sh, bash behaves as it should for the first time, which caused some problems. (which are now fixed, by the way)

Ok, please tell me how I can change the SOA on 150 domain files all at once with pointing and clicking. In bash, it's: sed -i s/oldSOA/newSOA/g * Until there's a way to do search and replace on any number of files that's easier than that, the command line will still be useful.

I read the announcement and it mentions "History traversal with arrow keys", but what I would really like doesn't seem to be mentioned (but perhaps it is possible with bash-2.05, I'm not much of a shell expert). In Matlab, the up-arrow key searches the history for commands that match all the characters on the line. No characters and it acts like a normal bash arrow, if "figure, plot" is at the beginning of the line, it will quickly scroll through all plotting commands that have been entered at the shell.
Any idea if this is possible?
Dara Parsavand
you can't use a GUI interface for ever thing(admin i mean). and switching between tasks is much easier with cli.for remote admin bash+screen+ssh is heaven. agreed. Point and click is easier but not always. I find cli is much easier when doing system administration(example samba, network issues).

Not everything is analogous to cars. Car analogies rarely work.
Bash is a portable tool that existed long before Linux did. It is not specific or particular to Linux. So why in the world does this get posted under the category of Linux ?

...and unaBASHedly so, if I may say so!
Bash can now store timestamps in the history and save them to the history file. This alone is worth the upgrade for me. The option to erase duplicates is pretty nice too.

The same can happen using the shell.
When you run a binary from the shell are you ever sure what files it's accessing?
If you log it, sure -- but there are tools to do that in the GUI, too.
Point and click is not necessarily intuitive. As Bruce Ediger said, the only intuitive interface is the nipple. After that, it's all learned.

The completion ability of bash has been steadily improving. There is a nice script here that sets up a lot of good completion rules for bash.

You like using a GUI and I like using a terminal. We're two people with two preferred methods of interacting with our machines. Your way is superior - for you. My way is superior - for me. There is no point (or obligation) to argue about which is better, since "better" is not a well-ordered set in this case.

Guys, I'm really so excited about this. I ran around proclaiming the news about bash-3.0 in my department. Not too many people got excited (I work in Psychology) but check this out:
[user@mitral user]$ echo $BASH_VERSION
2.05a.0(1)-release
[user@mitral user]$ a | b |cat
bash: a: command not found
bash: b: command not found
[user@mitral user]$ echo $?
0
[user@mitral bash-3.0]$ echo $BASH_VERSION
3.00.0(1)-release
[user@mitral bash-3.0]$ set -o pipefail
[user@mitral bash-3.0]$ a | b |cat
bash: a: command not found
bash: b: command not found
[user@mitral bash-3.0]$ echo $?

Feel the love!
With zsh (and I think some other shells), you can do one liner for loops without the do/done.
.jpg` <RETURN>
For example:
for i in img*.jpg <RETURN>
convert $i `basename $i
I do for loops all the time, and in my experience zsh is most flexable with them.
he's using convert, not mv.

Why dig through menus looking for a turkey sandwich when you could just type in that you want a turkey sandwich! Why people think that GUIs are easy to use is beyond me. Does look pretty, though.

Of course, your problem is that you are assuming that the very nature of a GUI is limited to what you've personally encountered.
Please explain to me what precludes a GUI from offering an advanced search tool, in which you can open up a property info dialog for the results and do bulk permission/property changes for. (Hint: nothing stops this from happening.)

This is just as quick, doesn't require you to memorise complicated syntax, and doesn't require filenames that follow a common pattern.

I would absolutely +love+ to be able to have more than 8 ANSI colors in bash. Back in the BBS days, we had EGA adapters that could do 64 colors.
Hell, it would be even better if we could define RRGGBB web-style colors.
THAT would be a very feature to have in my opinion. Does anyone know if this can be done using a VGA adapter? Would we have to do it in framebuffer or something?
Don't think that a small group of dedicated individuals can't change the world. It's the only thing that ever has.
If you have one or two images then I can agree with you, but when you have converted 1000 images then right-click -> Actions -> Convert To -> PNG is the hard way and typing a "complex" command _once_ is the easy way.... // fatal
You misunderstand. The right-click... action only has to be performed once, and it operates on all selected files. You don't have to perform the action a thousand times.

The point of a shell script is not to automate one-time generic tasks (that's what your context menu entry is for), but to automate one-time higly specific tasks (for which you can't reasonabily expect to have a predefined context menu entry) or unattended tasks that have to be executed many-times.
In the end, scripting everything is dumb, but requiring your presence to do the same task by hand over and over is dumber. You know the saying, "be quiet or I'll replace you with a very small shell script", there is a reason behind that.
It broke a script in 1 package, and was fixed in about 40minutes. What the hell are you talking about?
Starting up that explorer, selecting the files (manually checking if I have all of them, and only the right ones, perhaps, or having to scroll), then doing right click, is slower for me than typing in that command line.
Besides, I can still do the command line thing logged in over ssh, which is regularly.

But seriously, a command line user who can touch type at a decent speed can appear like Commander Data -- tacka tacka tacka as stuff scrolls by on the screen at an amazing rate. It's a skill, and if you don't have it, pointing and clicking might be just as fast or faster than having to look stuff up and then hunting and pecking. But if you use the computer alot, command line + touch typing is a set of skills worth investing some time developing.
I daresay it is. That's because you aren't comparing similar tasks any more. You are missing out starting up a shell, switching to the right directory, selecting a filename pattern that matches the files you want, etc. The previous command-line example assumed that you were logged in and had already chosen the files.
Besides, Konqueror offers shortcuts - if you think it's easier to type in a filename pattern, you can do so and have only those files showing.
What's your point? X is network transparent too, and Konqueror can perform the same tasks over ssh, ftp, and a range of other protocols even if X wasn't network transparent.

We've been talking about interactive use, not scripting. If I was going to script something, I'd use Python or Perl, not a shell script. Shell scripts are pretty hideous compared with any decent scripting language. "The right tool for the job" and all that...
I think only a few would even try to argue that they are. Most shells aren only somewhat available on non *nix OSs & many aren't available ay all off of them. Bash is, at least, reasonably available on most OSs. It is also the de facto shell standard, being found on linux and most newer *nix variants.
Portable shell scripts are probably more impeded when they use tools that aren't part of the shell & which aren't on the target system.
If you want true script portability, it is probably better to use something like perl. If you are concerned with writing short, simple scripts, shell scripts are fine. But not even sh is commonly interperated, & bash is VERY common, so bash isn't really an inappropriate choice.
You moron, I wasn't the original poster.
When you must break compatibility, you increment
the major number. This serves as a warning.
So, if a bash upgrade would break scripts, then
it should get a new major number. This is the case
for some of the POSIX alignment.
Mere features and bug fixes don't deserve a new
major number.
I like bash, but the one thing that it doesn't support (out-of-the-box anyway) is auto-completion a la W2K. In NT, when you hit tab, you can cycle through all the words that can complete the letters you typed... on bash, it shows you a list.
Is there a way to make bash behave more like W2K in this sense?
This would obviously be very useful in scripts where the success or failure of a command in the pipleine would not be as determinable as watching it on screen interactively.

It exposes that Gentoo is broken. There is a difference.

The one 'hole' is that command completion is a bit weird for the first element of a directory...if you have a directory that starts with 'ls', and you type ls <TAB> it will complete with 'ls'. Still, I find it to be very useful.

in my history, and I type
foo<TAB>
It complete that with the most recent command starting with "foo", and if I type
foo<UP>
it will cycle through the commands in history that start with "foo".

"Linux: Bash 3.0 Released", in the slashdot Linux section - does anyone notice anything wrong with this?
Linus did not write bash. bash is a GNU project. Come on, people - it's one thing to not worry about calling Linux OSes GNU/Linux, but it's another to attribute credit to a completely unrelated party!
Does bash have "r" yet? Or has it always and I've just never found it? I don't want stupid csh "!" to repeat my commands.
And I set up bash so I can, for instance, move from rc2.d to rc3.d by typing
$ cd 2 3
?
The FSF actually does development in a very closed manner when it can (the gcc egcs split was partly because of this)
..and pshaw. egcs was a radical rewrite of GCC; it was run as a separate research project in order to be able to make huge changes and get releases out for testing without blocking bugfix work on the old, stable codebase. (Since radical rewrites tend to be high-risk.)

I take it you're showing how sometimes backspacing or moving the cursor backwards along a line that exceeds the terminal's width does a strange duplication thing, making it almost impossible to edit? In my own experience, there are two main reasons why this might happen:
1. you changed the *term window size while constructing the command, so use this to enable checks for this condition: shopt -s checkwinsize
2. you have an improperly terminated escape code in your prompt. I had this problem until I started using codes like this: \[\e[0m\] rather than the other style, which I now forget.
W2K style is a real pain, and to me it seems worth installing a few hundred MB of cygwin to get the bash behaviour! I'd be more interested in knowing how to get Bash behaviour in W2K. Any ideas?
It's not necessary to start on an empty line.
This is why error messages in any language should be accompanied by an error code (usually numerical but it doesn't have to be) that is unique to the root cause of the error. Then you can search on this error code regardless of the language of the message.
I don't think you understand. He was trying to be funny.

IANAL but write like a drunk one.
By "real debugger" I mean something that can be used to reliably debug 10,000-line "configure" scripts and debug around control flow, handle sourcing multiple files, show a call stack, debug into or skip over into functions.
Not another one.
