Description Ortwin Glueck 2007-05-11 08:28:33 UTC

As of app-shells/bash-3.2_p15-r1 subexpressions in regular expressions are broken. Scripts that worked before now behave erronous.

Reproducible: Always

Steps to Reproduce:
[[ "a b c" =~ "a (.) c" ]]
echo ${BASH_REMATCH[1]}
Actual Results:  
Returns nothing

Expected Results:  
b

Not really.

Puh... Quite a nasty change that breaks lots of my scripts.

The new way to write these sort of regex is:
V="a b c"
RE="a (.) c"
[[ $V =~ $RE ]]
