  49 .sp
  50 .LP
  51 The \fBegrep\fR (\fIexpression grep\fR) utility searches files for a pattern of
  52 characters and prints all lines that contain that pattern. \fBegrep\fR uses
  53 full regular expressions (expressions that have string values that use the full
  54 set of alphanumeric and special characters) to match the patterns. It uses a
  55 fast deterministic algorithm that sometimes needs exponential space.
  56 .sp
  57 .LP
  58 If no files are specified, \fBegrep\fR assumes standard input. Normally, each
  59 line found is copied to the standard output. The file name is printed before
  60 each line found if there is more than one input file.
