grep 2.5

[Dave Yearke]

Hi,

In grep 2.5, "egrep" and "fgrep" are no longer separate executables,
but links to the "grep" program.  The logic that determines what name
it was invoked as is incomplete, as some of us prefix GNU programs
with "g" to distinguish them from system-delivered programs with the
same names, eg. "ggrep" (I believe this is the reason why egrep and
fgrep were separate programs in previous releases).  This patch is
one possible solution to this problem:

      program_name = strrchr (program_name, '/') + 1;
  
!   if (!strcmp(program_name, "egrep"))
      setmatcher ("egrep");
!   if (!strcmp(program_name, "fgrep"))
      setmatcher ("fgrep");
  
  #if defined(__MSDOS__) || defined(_WIN32)
--- 1289,1297 ----
    if (program_name && strrchr (program_name, '/'))
      program_name = strrchr (program_name, '/') + 1;
  
!   if ((!strcmp(program_name, "egrep")) || (!strcmp(program_name, "gegrep")))
      setmatcher ("egrep");
!   if ((!strcmp(program_name, "fgrep")) || (!strcmp(program_name, "gfgrep")))
      setmatcher ("fgrep");
  
  #if defined(__MSDOS__) || defined(_WIN32)


I hope this helps.
