grep warning: obsolescent (g)egrep

[Frank Blechschmidt]

Description

Observed warning when opening a new terminal or executing a command:

gegrep: warning: gegrep is obsolescent; using ggrep -E

This appears to be caused by gnu-utility and must have started with a recent grep upgrade.

➜ ~ grep --version
grep (BSD grep, GNU compatible) 2.6.0-FreeBSD
➜ ~ ggrep --version
ggrep (GNU grep) 3.8
