RPM of version bash 3.2 for AIX 5.3 is available at
http://www-03.ibm.com/systems/power/software/aix/linux/toolbox/download.html
|
The installation requires one command:
rpm -i bash-3.2-1.aix5.2.ppc.rpm
You need also include it into the list of shells to use with FTP.
If you need a refresher information, see Bash as an Enterprise-level Shell. The topics include short explanations of key features and techniques for system administrators, such as

From foreword:
We urge everyone to study this entire book. Every chapter hits a different topic
using a different approach. The book is written this way to emphasize that there is
never only one technique to solve a challenge in UNIX. All the shell scripts in this book
are real-world examples of how to solve a problem. Thumb through the chapters, and
you can see that we tried to hit most of the common (and some uncommon!) tasks
in UNIX. All the shell scripts have a good explanation of the thinking process, and
we always start out with the correct command syntax for the shell script targeting a
specific goal. I hope you enjoy this book as much as I enjoyed writing it. Let’s get
started!
A must-have for all levels of *nix users. , August 1, 2004 This review is from: Mastering UNIX Shell Scripting (Paperback)
By Bindlestiff (rixtertech.com) - See all my reviews The breadth of real-world examples make the difference between this book and most reference texts. It's true that it's written for korn, but I've had little trouble adapting for Bash; many of the scripts run almost unchanged and the ones that don't provide a useful opportunity for exercise in adaptation. The authors prose is clear. His attitude is a bit challenging; he says early on that that his intention is to teach you how to -solve problems- by shell scripting, NOT to present a ream of canned solutions. This is NOT a reference text for any particular shell, you'll still need plenty of O'Reilly books, a web browser & etc.
This book has enabled me to write a major project using scripting as the glue to hold together a hefty mass of file-moving daemons, fax/paging engines, python UI code, PostGreSQL database engine, networking/email, SSH, and Expect scripts on a Gnu Linux platform. I absolutely could not have done it without this book and I'm very grateful to Mr Michael for his work. If a later edition could more closely serve the needs of the masses by presenting more Bash examples and maybe throwing in a CD it would be a 5-star text.

#, precedes each line of a comment.Command readability and step-by-step comments are just the very basics of a
well-written script. Using a lot of comments will make our life much easier when we
have to come back to the code after not looking at it for six months, and believe me; we
will look at the code again. Comment everything! This includes, but is not limited to,
describing what our variables and files are used for, describing what loops are doing,
describing each test, maybe including expected results and how we are manipulating
the data and the many data fields. A hash mark,

script stub that follows is on this book’s companion web site at www.wiley.com/go/michael2e

(continued)The shell script starter shown in Listing 1-1 gives you the framework to start writing
the shell script with sections to declare variables and files, create functions, and write
the final section,
BEGINNING OF MAIN, where the main body of the shell script iswritten.
Repeating an argument
You can repeat the last argument of the previous command in
multiple ways. Have a look at this example:
$ mkdir /path/to/dir
$ cd !$
The second command might look a little strange, but it will just cd to /path/to/dir.
Some keyboard shortcuts for editing
There are some pretty useful keyboard shortcuts for editing in bash. They might
appear familiar to Emacs users:
• Ctrl + a => Return to the start of the command you're typing
• Ctrl + e => Go to the end of the command you're typing
• Ctrl + u => Cut everything before the cursor to a special clipboard
• Ctrl + k => Cut everything after the cursor to a special clipboard
• Ctrl + y => Paste from the special clipboard that Ctrl + u and Ctrl + k save
their data to
• Ctrl + t => Swap the two characters before the cursor (you can actually use
this to transport a character from the left to the right, try it!)
• Ctrl + w => Delete the word / argument left of the cursor
• Ctrl + l => Clear the screen
Redirecting both Standard Output and Standard
Error:
# ls -ltR 2>&1 > /tmp/temp.txt
Specify this in .bashrc
Make Bash append rather than overwrite the history on disk:
# shopt -s histappend
Whenever displaying the prompt, write the previous line to disk:
# export PROMPT_COMMAND=’history -a’
To erase duplicate entries in History.
# export HISTCONTROL=erasedups
(or)
# export HISTCONTROL=ignoreboth
To see the history with timestamps
# export HISTTIMEFORMAT="%d/%m/%Y-%H:%M:%S "
To set the Size of the history HISTSIZE: The number of commands to remember in
the command history. The default value is 500.
# export HISTSIZE=500

Ick.
Sorry, couldn't help it. Since Bash is listed on the AIX Toolbox page I
suspect it's not a part of the base installation. It should be on the
Toolbox CD or you can get it from this site:
http://www-03.ibm.com/servers/aix/products/aixos/linux/download.html
both bash and viM are installed in my home folder. i have added their location in my PATH. the arrows work now by setting TERM to xterm instead of ansi. i can deal with Home and End keys not working.
