fmlgrep(1F)                                                     fmlgrep(1F)


   NAME
         fmlgrep - search a file for a pattern

   SYNOPSIS
         fmlgrep [options] limited_regular_expression [file ...]

   DESCRIPTION
         fmlgrep searches file for a pattern and prints all lines that contain
         that pattern.  The fmlgrep function uses limited regular expressions
         (expressions that have string values that use a subset of the
         possible alphanumeric and special characters) like those used with
         ed(1) to match the patterns.  It uses a compact non-deterministic
         algorithm.

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

         If file 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.

         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.
         -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.

   DIAGNOSTICS
         fmlgrep returns the following exit values:

         0  if the pattern is found (i.e., TRUE)
         1  if the pattern is not found (i.e., FALSE)
         2  if an invalid expression was used or file is inaccessible


   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.
