User Commands fgrep(1)
NAME
fgrep - search a file for a fixed-character string
SYNOPSIS
/usr/bin/fgrep [-bchilnsvx] -e pattern_list [file...]
/usr/bin/fgrep [-bchilnsvx] -f file [file...]
/usr/bin/fgrep [-bchilnsvx] pattern [file...]
/usr/xpg4/bin/fgrep [-bchilnqsvx] -e pattern_list [-f file]
[file...]
/usr/xpg4/bin/fgrep [-bchilnqsvx] [-e pattern_list] -f file
[file...]
/usr/xpg4/bin/fgrep [-bchilnqsvx] pattern [file...]
DESCRIPTION
The fgrep (fast grep) utility searches files for a character
string and prints all lines that contain that string. fgrep
is different from grep(1) and from egrep(1) because it
searches for a string, instead of searching for a pattern
that matches an expression. fgrep 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. These characters have
special meaning to the shell. Therefore, to be safe, enclose
the entire string within single quotes (').
If no files are specified, fgrep assumes standard input.
Normally, each line that is found is copied to the standard
output. The file name is printed before each line that is
found if there is more than one input file.
OPTIONS
The following options are supported for both /usr/bin/fgrep
and /usr/xpg4/bin/fgrep:
-b Precedes each line by the block number on
which the line was found. This can be useful
in locating block numbers by context. The
first block is 0.
-c Prints only a count of the lines that con-
tain the pattern.

User Commands fgrep(1)
-e pattern_list Searches for a string in pattern-list. This
is useful when the string begins with a -.
-f pattern-file Takes the list of patterns from pattern-
file.
-h Suppresses printing of files when searching
multiple files.
-i Ignores upper/lower case distinction during
comparisons.
-l Prints the names of files with matching
lines once, separated by new-lines. Does not
repeat the names of files when the pattern
is found more than once.
-n Precedes each line by its line number in the
file. The first line is 1.
-s Works silently, that is, displays nothing
except error messages. This is useful for
checking the error status.
-v Prints all lines except those that contain
the pattern.
-x Prints only lines that are matched entirely.
/usr/xpg4/bin/fgrep
The following options are supported for /usr/xpg4/bin/fgrep
only:

User Commands fgrep(1)
-q Quiet. Does not write anything to the standard out-
put, regardless of matching lines. Exits with zero
status if an input line is selected.
OPERANDS
The following operands are supported:
file Specifies a path name of a file to be
searched for the patterns. If no file
operands are specified, the standard input
will be used.
/usr/bin/fgrep
pattern Specifies a pattern to be used during the
search for input.
/usr/xpg4/bin/fgrep
pattern Specifies one or more patterns to be used
during the search for input. This operand is
treated as if it were specified as -e
pattern_list.
USAGE
See largefile(5) for the description of the behavior of
fgrep when encountering files greater than or equal to 2
Gbyte ( 2**31 bytes).
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment
variables that affect the execution of fgrep: LC_COLLATE,
LC_CTYPE, LC_MESSAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 If any matches are found
1 If no matches are found

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 only by the size of the available virtual
memory.
/usr/xpg4/bin/fgrep
The /usr/xpg4/bin/fgrep utility is identical to
/usr/xpg4/bin/grep -F (see grep(1)). Portable applications
should use /usr/xpg4/bin/grep -F.
