Top Forums Shell Programming and Scripting Awk: Dealing with whitespace in associative array indicies Post 302942736 by Chubler_XL on Thursday 30th of April 2015 11:34:21 PM

Code:
$ echo | awk 'BEGIN { a[contains whitespace]="abc"; if (contains purplespace in a) print "index exists"}'
index exists FALSE POSITIVE

This is not a false positive you are concatenating two null variables producing a null value just like:
contains whitespace == contains purplespace

Consider:

Code:
echo | awk 'BEGIN { whitespace="ws"; purplespace="ps"; a[contains whitespace]="abc"; if (contains purplespace in a) print "index exists"}'
