fmlgrep

fmlgrep(1F)							   FMLI Commands						       fmlgrep(1F)

NAME

       fmlgrep - search a file for a pattern

SYNOPSIS

       fmlgrep [-b] [-c] [-i] [-l] [-n] [-s] [-v] limited_regular_expression [filename...]

DESCRIPTION

       fmlgrep	searches  filename for a pattern and prints all lines that contain that pattern. fmlgrep uses limited regular expressions (expres-
       sions that have string values that use a subset of the possible alphanumeric and special characters) like those described on the  regexp(5)
       manual page to match the patterns. It uses a compact non-deterministic algorithm.

       Be careful when using  FMLI special characters (for instance, $, `, ', ") in limited_regular_expression. It is safest to enclose the entire
       limited_regular_expression in single quotes ' ... '.

       If filename is not specified, fmlgrep assumes standard input. Normally, each line matched is copied to standard output. The  file  name	is
       printed before each line matched if there is more than one input file.

OPTIONS

       The following options are supported:

       -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.

       -i	Ignore upper/lower case distinction during comparisons.

       -l	Print only the names of files with matching lines, separated by new-lines. 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).

       -s	Suppress error messages about nonexistent or unreadable files.

       -v	Print all lines except those that contain the pattern.

EXIT STATUS

       The following exit values are returned:

       0	if the pattern is found (that is, TRUE)

       1	if the pattern is not found (that is, FALSE)

       2	if an invalid expression was used or filename is inaccessible

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWcsu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       egrep(1), fgrep(1), fmlcut(1F), grep(1), attributes(5), regexp(5)

NOTES

       Lines are limited to  BUFSIZ characters; longer lines are truncated. BUFSIZ is defined in /usr/include/stdio.h.

       If there is a line with embedded nulls, fmlgrep will only match up to the first null; if it matches, it will print the entire line.
