Korn Shell Script

1. The problem statement, all variables and given/known data:

Write a korn shell script with an alfanumeric string as argument. The script lists the file's names in the current directory that contain the given string as substring and that can be read and written.

2. Relevant commands, code, scripts, algorithms:

I can read the string from standard input and also print on screen the file's names which contain the string, but only if use the name of the file as parameter. I can't search the string among all the regular files in my directory and i have no idea on how to filter files basing on permissions.

3. The attempts at a solution (include all code and scripts):
Code:
#!/bin/ksh
echo "Write a string"
read 
echo "Files which contain the string are:"
find . -type f | grep -l $REPLY stringhe.rtf

stringhe.rtf is a text file with some random strings created by me.
4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
Università degli Studi di Trieste, Trieste, Italy, Vidimari, IN108

SHCOMP(1)						       Korn shell utilities							 SHCOMP(1)

NAME
shcomp - compile a shell script SYNOPSIS
shcomp [ options ] [infile [outfile]] DESCRIPTION
Unless -D is specified, shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh can read and execute with the same effect as the original script. Since aliases are processed as the script is read, alias definitions whose value requires variable expansion will not work correctly. If -D is specified, all double quoted strings that are preceded by $ are output. These are the messages that need to be translated to locale specific versions for internationalization. If outfile is omitted, then the results will be written to standard output. If infile is also omitted, the shell script will be read from standard input. OPTIONS
[D dictionary] Generate a list of strings that need to be placed in a message catalog for internationalization. [n noexec] Displays warn- ing messages for obsolete or non-conforming constructs. [v verbose] Displays input from infile onto standard error as it reads it. EXIT STATUS
0 Successful completion. >0 An error occurred. SEE ALSO
