Multiple `-e' to egrep are not portable. On IRIX 6.5 and Solaris
2.5.1 only the last one is honored:
- > echo "foo\nbar" | egrep -e 'foo' -e 'bar'
+ > printf "foo\nbar" | egrep -e 'foo' -e 'bar'
bar
- > echo "foo\nbar" | egrep -e 'bar' -e 'foo'
+ > printf "foo\nbar" | egrep -e 'bar' -e 'foo'
foo

An alternative would have been to use `sed', unfortunately
