Version 2.4.2 of egrep does not seem to work as expected. When I execute the
command
egrep "^[a-z]" data.txt
on the attached sample file, egrep does not display only those records
beginning with lower case letters.
Similarly,
egrep "^[A-Z]" data.txt
does not return just those records beginning with upper case letters.
Fortunately, I was able to do what I wanted to do by using the posix constructs
[:upper:] and [:lower:] that worked just fine.
I managed to dig out an old copy of egrep version 2.3, and it works as expected.
Is this change to version 2.4.2 an oversight or a deliberate modification?
