Bash Version: 4.1 Patch Level: 7 Release Status: release Description: I have a regular expression with a Ctrl-A character in the middle and I can no longer get it to match with bash 4.1.7. However I can get regular expressions to match as long as the Ctrl-A is at the beginning or end of the regular expression so I suspect this is a bug. Using 'shopt -s compat31' does allow the match to occur with a Ctrl-A in the middle but I'd prefer to not use this if I don't have to. Repeat-By: -bash-4.1$ [[ "helloworld" =~ llo ]] && echo match match -bash-4.1$ [[ "helloworld" =~ world ]] && echo match match -bash-4.1$ [[ "helloworld" =~ world$ ]] && echo match match -bash-4.1$ [[ "helloworld" =~ ]] && echo match match -bash-4.1$ [[ "helloworld" =~ oworld$ ]] && echo match -bash-4.1$ shopt -s compat31 -bash-4.1$ [[ "helloworld" =~ oworld$ ]] && echo match match
