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.
fgrep processes supplementary code set characters according to
the locale specified in the LC_CTYPE environment variable [see
LANG on environ(5)], except as noted under the -i option
below. Pattern searches are performed on characters, not
bytes.
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; valid for single-byte characters only.

-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. If the
input file is stdin, then a message such as ``(standard
input)'' will be written, depending upon the message
locale.
-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.
FILES
/usr/lib/locale/locale/LC_MESSAGES/uxcore
language-specific message file [See LANG on environ(5).]

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).
NOTICES
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 bytes;
longer lines are truncated. BUFSIZ is defined in
/usr/include/stdio.h.
