Topic: Bash

Speaker: William Park

Description: Bash-3.0 was released recently. Two notable additions from Bash-2.05b are regex test '=~' in [[...]] and integer sequence generator {x..y}. Bash patch written by William Park

       http://freshmeat.net/projects/bashdiff/
       http://freshmeat.net/projects/basp/

extends Bash's capability even more, giving other modern scripting languages a run for their money.

His patch incorporates many useful features from Awk, Python, Zsh, Ksh, and others. In the main core, it adds the following:

new brace expansion {a..b}
new parameter expansion ${var|...}
new command substitution $(=...)
string concatenation (+=)
extended for, while, and until loops
extended case statement
new try-block with integer exception.

As builtin commands, it adds the following:

extended set, read, echo builtins
sscanf(3) wrapper
variety of array and regex(3) operations
GDBM, SQLite, PostgreSQL, and MySQL database interfaces
an HTML template engine (BASP).

He will give a quick tutorial on above features. People are encouraged to try it out, and any feedback on possible applications or feature requests are most welcome. Since everything is online, there will be no handouts or projector. Just chalk and blackboard.
