I recently responded to a similar question of yours here: https://www.unix.com/unix-dummies-que...#post302187223

Code:
#!/bin/sh

case $# in 0|1) echo "syntax: $0 date files ..." >&2; exit 2;; esac

date=$1
shift

awk -v d="$date" '$0 ~ d' "$@"

This expects the date as the first parameter, and a list of files as the remaining parameters. Those are passed through to awk in "$@" after the first argument (the date) has been shifted off and passed to the awk script as a variable.

I took out the { print } because that is the default action; this is probably less readable, so if you don't use awk much, it might be safer to leave it in.

Of course, this simple script is exactly equivalent to grep without any options or other bells & whistles.

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
