'The egrep and fgrep commands have been deprecated since 2007. Beginning with GNU Grep 3.8 today, calling these commands will now issue a warning to the user that instead they should use grep -E and grep -F, respectively. ...
From grep's updated manual:
... egrep and fgrep were not standardized by POSIX and are no longer needed.'
Found this page <https://pubs.opengroup.org/onlinepubs/9699919799/xrat/V4_xcu_chap04.html> which indicates that those commands were dropped from the Open Group specs some years ago. Interesting, though, that the Debian package maintainers are having second thoughts about the deprecation warnings <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1019335>, and have decided to disable them for now, pending a more thorough discussion of the issue. Not withstanding these commands were never considered “standard”, the thought of their removal seems to have awakened a lot of controversy.
'- Regular expressions with stray backslashes now cause warnings'
Yes, I saw that happen a lot during the Debian Unstable upgrade I did earlier today. But then, that’s why they call it Debian Unstable ...
