Thanks!

In case it's helpful, here's what the wrappers look like:
````
$ cat /usr/bin/egrep
#!/bin/sh
cmd=${0##*/}
echo "$cmd: warning: $cmd is obsolescent; using /bin/grep -E" >&2
exec /bin/grep -E "$@"


$ cat /usr/bin/fgrep
#!/bin/sh
cmd=${0##*/}
echo "$cmd: warning: $cmd is obsolescent; using /bin/grep -F" >&2
exec /bin/grep -F "$@"
```

May be useful to put in PATH temporarily or something.
