Choosy Xastir programmers choose Perl...
I've done sed/awk/Perl/C, and others. C sucks for string handling
as there are a lot of details you need to take care of.
Perl has sed and awk-type of things built-in, so with the one
language you can do regular expression editing of strings quite
easily. You'll find a lot more Perl people these days than sed or
As far as Scott's comment about readability, you can make Perl as
readable as anything else, it's just a language. Some Perl
programmers used to think it was cool to make terse scripts, but the
readability suffers and they become much less maintainable.
One of the weirdnesses of Perl is that a default variable gets used
if none is specified. If you don't know that particular fact it's
hard to read a lot of Perl code 'cuz you don't know what's being
worked on. Other than that it's a lot like C or Pascal or Java.
You can also do object-oriented programming in Perl, or
mix-and-match some of that with structured programming.
For Perl books these are the ones I use:
The "Perl Cookbook" is the most useful overall. It has working
examples of many of the types of things you might want to do, so
you can borrow code bits from it.
For getting started learning the language "Learning Perl" works,
although I don't use it that much anymore. I use "Programming Perl"
mostly as a reference but really have to have it on the bookshelf
'cuz I do refer to it.
"Mastering Regular Expressions" is another good one to have on the
bookshelf. I don't refer to it often, but when I need more advanced
stuff I _really_ need that book.
