I totally agree here with Karl, obsoleting fgrep and egrep is the
wrong way to go. It's built into too many scripts world-wide, as
well as burned into the "finger ROMs" of too many users. Not to mention
all the books / training materials that talk about them that people
may have.
Thanks,
Arnold

Is the use of diagnostic warnings like this supported by POSIX?
Personally, I'd rather have tools

The warning messages are merely annoying. Returning a non-zero exit
status would break scripts, and in many cases

For me (and according to historical practice), an unnecessary \ is not
invalid. So, not surprisingly, I, on the other hand, would rather have
grep provide a way to turn off t
[ef]grep
I guess my basic issue is that I don't understand the benefit of the new
warning. It causes a lot of trouble. What is the countervailing
positive benefit?
$ grep '\Q' /dev/null
grep: warning: stray \ before Q
It would be nice to be able to turn those off too. (It hit me to
simpler solution to undeprecate the tools in documentation and have
them be official GNU-enhancements as they de-facto has been for the
past 20+ years

My pet issue was the inconsistency between documentation and reality,

I think the simplest way to fix that is t
