Well, for the history of bsdgrep, you have to go back to freegrep: https://jameshoward.us/software/freegrep/ <https://jameshoward.us/software/freegrep/> but the most significant changes are likely to be due to Gabor: https://wiki.freebsd.org/BSDgrep <https://wiki.freebsd.org/BSDgrep> Pedro. _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
