[ale] Bash shell text ALE-NW

[Dow Hurst]

If anyone wants to come by and pick up a copy of the Bash Shell packet 
that David put together, please let me know you are coming and I will 
print it for you.  I did not print the latest version by mistake for the 
meeting so some material was missing from the handout.  Of course, just 
check www.ale.org for the latest version over the web.  I'd like to make 
the printed copy available since I feel pretty stupid for printing the 
wrong file!  Anyway, there is a lot of great material for learning the 
bash shell here so check the website or drop me a line saying your 
coming for your copy.  I could bring some to the next meeting for those 
interested.

I thought we had a fun meeting once we got over the real diversity of 
backgrounds concerning the bash shell.  David did a good job trying to 
help out those who didn't have a clue along with lots of help from the 
crowd.  We had quite a crowd, at least 35-45 people.

Hopefully in the future we can reapproach this topic in an advanced talk 
as David hardly got to start on the real meat of what he had prepared. 
 The LUG at KSU will be holding meetings starting this Fall semester for 
students with topics specifically focused for newbies.

Here is the answer to the shell history problem:

 >!579:2:s/ux//

Which if the 579th command was:
 >ps auxw | grep dhurst | awk '{print($2)}'  |  xargs kill -HUP

then what you would get would be:

 >ps aw | grep dhurst | awk '{print($2)}'  |  xargs kill -HUP
                   
Am I right?  This is straight out of the bash man page.  The !579 
selects that command out of the history list.  The : separates the parts 
of the command.  The 2 is the second "word" in the command, which I 
believe is space delimited.  The "s/ux//" substitutes the "ux" of "auxw" 
with nothing.
