Sorry, I just noticed that the one-liner posted above will work only if, within the double-brackets:
(a) there's a single string with no embedded "|"s
(b) there are exactly two strings with exactly one embedded "|"
So, cases like the following:
Code:
[[abc|def|ghi]][[abc|def|ghi|jkl]]
will not be matched, and hence will not be altered by the script.
An example follows (I've modified your data a bit):
Code:
$
$
$ cat f8
There are many types and traditions of anarchism, some of which are [[mutually exclusive]].
Strains of anarchism have been divided into the categories of [[social anarchism|social]]
and [[individualist anarchism]] or similar dual classifications. Anarchism is often
considered to be a radical [[left-wing]] ideology, and much of [[anarchist economics]]
and [[anarchist law|anarchist legal philosophy]] reflect [[anti-statism|anti-statist|non-statist]]
interpretations of [[anarcho-communism|communism]], [[collectivist anarchism|collectivism]],
[[anarcho-syndicalism|syndicalism|blah|BLAH]] or [[participatory economics]].

$$ # Old script that does NOT work for more than 2 delimited tokens within double-brackets
$ perl -plne 's/\[\[[^|]*?\|*([^|]*?)\]\]/$1/g' f8

The fix for this is to modify the regex so that it:
(a) matches all characters, including "|"s, as much as possible
(b) matches a single "|" character (if it exists at all)
(c) matches the remainder that does not include "|", and set it to position 1
Something like this:
Code:
$
$ cat f8

As i am new to perl i do not know about where to search the packages and all. Any help is appreciated.
