Well, it looks like that did affect it, according to a
http://en.wikipedia.org/wiki/Bash#In-process_regular_expressions
Basically, the single quotes surrounding the regex become part of the
regex. So the above code becomes:
if [[ "foo.tex" =~ ^(.*)\.tex$ ]]
then
file=${BASH_REMATCH[1]}
echo "File is: $file"
else
echo "Not a TeX file"
fi
That's a pretty significant change. A lot of scripts will be broken.
More warning should have been given to users about this.
