This is GNU fgrep, version 1.1. Eventually it will disappear into the single grep program mandated by POSIX, but for now it should be a compatible replacement for UNIX fgrep. The options are the same as those of GNU egrep, and are a proper superset of the fgrep options on all UNIX systems I am aware of. I have not tried comparing this performance-wise to any of the various other free fgreps that are floating around, but it should never be any slower, and for demanding applications will probably be substantially faster. For single fixed-string searches the speed is about the same as that of GNU egrep; for multiple fixed strings it is substantially faster. Correspondence regarding this program should be addressed directly to me, mike@ai.mit.edu, *not* bug-gnu-utils. Enjoy. Mike Haertel mike@ai.mit.edu
