NAME
      fgrep - search a file for a character string

SYNOPSIS
      fgrep [options] string [file . . . ]

DESCRIPTION
      fgrep (fixed string grep) searches files for a character string and
      prints all lines that contain that string.  fgrep is different from grep
      and egrep because it searches for a string instead of searching for a
      pattern that matches an expression.  It uses a fast and compact
      algorithm.

      The characters $, *, [, ^, |, (, ), and \ are interpreted literally by
      fgrep, that is, fgrep does not recognize full regular expressions as does
      egrep.  Because these characters have special meaning to the shell, it is
      safest to enclose the entire string in single quotes ' . . . '.

      If no files are specified, fgrep assumes standard input.  Normally, each
      line found is copied to the standard output.  The filename is printed
      before each line found if there is more than one input file.

      Command line options are:

      -b    Precede each line by the block number on which it was found.  This
            can be useful in locating block numbers by context (first block is
            0).
      -c    Print only a count of the lines that contain the pattern.
      -h    Suppress printing of filenames when searching multiple files.
      -i    Ignore uppercase/lowercase distinction during comparisons.
      -l    Print the names of files with matching lines once, separated by
            newlines.  Does not repeat the names of files when the pattern is
            found more than once.
      -n    Precede each line by its line number in the file (first line is 1).
      -v    Print all lines except those that contain the pattern.
      -x    Print only lines matched entirely.
      -e special_string
            Search for a special_string (string begins with a -).
      -f file
            Take the list of strings from file.

DIAGNOSTICS
      Exit status is 0 if any matches are found, 1 if none, 2 for syntax errors
      or inaccessible files (even if matches were found).

NOTES
      Ideally there should be only one grep command, but there is not a single
      algorithm that spans a wide enough range of space-time tradeoffs.  Lines
      are limited to BUFSIZ characters; longer lines are truncated.  BUFSIZ is
