Writing Code

1. The problem statement, all variables and given/known data:
Write a script that will perform the grep command on a user defined file and a user defined pattern

2. Relevant commands, code, scripts, algorithms:
must use grep command (that is the only piece of information that was given)

3. The attempts at a solution (include all code and scripts):

Code:

clear
loop=y
while [ "$loop" = y ]
do
 tput cup 2 23; echo " ~*~*~*~*~*~*~*~*~*~*~*~ "
 tput cup 3 23; echo " * Search for a Pattern * "
 tput cup 4 23; echo " ~*~*~*~*~*~*~*~*~*~*~*~ "
 tput cup 6 5; echo "Type in the pattern and path to the file you want to search for below," 
 tput cup 7 5; echo "or type Q to return to previous screen."
 tput cup 9 10; echo "Ex. : help /home/james/project/help"
 tput cup 11 5; 
read choice || continue
  case $choice in
    [Q,q]) clear; exit ;;
    *) grep * ;; esac
done

I understand that the grep * is telling it to look for a wildcard, however, I am not sure what it is that I need to write on that line.

4) Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
Fort Valley State University, Fort Valley Ga, Dr. Wang, CSCI 3331

tput

TPUT(1) 						    BSD General Commands Manual 						   TPUT(1)

NAME

     tput, clear -- terminal capability interface

SYNOPSIS

     tput [-T term] attribute ...
     clear

DESCRIPTION

     The tput utility makes terminal-dependent information available to users or shell applications.  When invoked as the clear utility, the
     screen will be cleared as if
	   tput clear
     had been executed.  The options to tput are as follows:

     -T      The terminal name as specified in the termcap(5) database, for example, ``vt100'' or ``xterm''.  If not specified, tput retrieves the
	     ``TERM'' variable from the environment.

     The tput utility outputs a string for each attribute that is of type string; a number for each of type integer.  Otherwise, tput exits 0 if
     the terminal has the capability and 1 if it does not, without further action.

     If an attribute is of type string, and takes arguments (e.g. cursor movement, the termcap ``cm'' sequence) the arguments are taken from the
     command line immediately following the attribute.

     The following special attributes are available:

     clear	   Clear the screen (the termcap(5) ``cl'' sequence).

     init	   Initialize the terminal (the termcap(5) ``is'' sequence).

     longname	   Print the descriptive name of the user's terminal type.

     reset	   Reset the terminal (the termcap(5) ``rs'' sequence).

EXIT STATUS

     The exit status of tput is as follows:

     0	     If the last attribute attribute argument is of type string or integer, its value was successfully written to standard output.  If the
	     argument is of type boolean, the terminal has this attribute.

     1	     This terminal does not have the specified boolean attribute.

     2	     Usage error.

     3	     No information is available about the specified terminal type.

SEE ALSO

     termcap(5), terminfo(5)

STANDARDS

     The tput utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     The tput utility appeared in 4.4BSD.

BUGS

     The tput utility cannot really distinguish between different types of attributes.

     Some termcap entries depend upon having a '%' in them that is just a '%' and nothing more.  Right now we just warn about them if they do not
     have a valid type declaration.  These warnings are sent to stderr.
