- Subject: Bash regex tests wh'appen?
I upgraded quite a lot of bash versions in one go, and one of my
shell-scripts broke. I've reproduced it to a simple test case which shows
that either regex tests have turned into non-reg-ex text matches, or that I've
really misunderstood something here. I checked the last few release
announcements and didn't see anything about the behaviour of =~ changing.
/artimi/tools/cygwin/bin $ if [[ "foo.h" =~ "foo.h" ]] ; then echo "yes" ;
else echo "no" ; fi
yes
/artimi/tools/cygwin/bin $ if [[ "foo.h" =~ ".*foo.h" ]] ; then echo "yes" ;
else echo "no" ; fi
no
/artimi/tools/cygwin/bin $ if [[ "foo.h" =~ "\.\*foo.h" ]] ; then echo "yes" ;
else echo "no" ; fi
no
/artimi/tools/cygwin/bin $ cygcheck -c bash
Cygwin Package Information
Package Version Status
bash 3.2.9-10 OK
Reverting to 3.1-6 restores the expected behaviour (results above become
yes, yes, no).
cheers,
