I use RegEx Buddy to prototype and debug my regular expressions. RegEx Buddy allows me to choose between a number of different regular expression engine types (.NET, Java, Perl, GNU BRE, GNU ERE, POSIX, BRE, POSIX ERE etc).
What regular expression engine does bash use (for example in
case statements)? I'm running Centos 5.5 32 bit and bash 3.2.25(1):
[kevin@mon01 scratch]$ bash --version GNU bash, version 3.2.25(1)-release (i686-redhat-linux-gnu) Copyright (C) 2005 Free Software Foundation, Inc.
I'm guessing it'll be GNU BRE or GNU ERE?
