Despite POSIX states that: > The old egrep and fgrep commands are likely to be supported for many > years to come as implementation extensions, allowing historical > applications to operate unmodified. GNU grep 3.8 started to warn[1]: > The egrep and fgrep commands, which have been deprecated since > release 2.5.3 (2007), now warn that they are obsolescent and should > be replaced by grep -E and grep -F. Prepare for their removal in the future.
