Global Regular Expression Print

NAME
    GREP                        Find occurences of regular expressions

SYNOPSIS
    grep [-cfhlnvyz] <regular expression>[<regular expression>]... [<file>...]

DESCRIPTION
    Grep is a Unix utility that permits the users to search a given set
    of files for the occurence of various regular expression(s). A regular
    expression is a text string that provides for the selection of very
    specific strings in the text being searched.

OPTIONS
    -c      count matching lines, no output for zero
    -f      no regular expression given; file contains regular expressions
    -h      no filename headers on lines
    -l      list file names with match
    -n      show line numbers
    -v      show only lines that don't match
    -z      count lines (even if if zero)


EXAMPLES
    The best way to learn how to use grep is to try it. Grep is written to
    accept standard input (stdin) in lieu of a file. This permits grep to
    use text piped from another program such as a compiler, linker etc and
    select the desired lines.

            lc test.c | grep ^Warning,^Error

    This example will show any lines generated by the compiler that start
    with either Warning or Error. Please note that grep is case sensitive.

            grep -f regexp *.c

    This example will look for all regular expressions listed in the file
    regexp in all text files with .C as it's extent.

    Please refer to the text file on regular expressions for additional
    examples.
