They're not questions as much as "make this happen"

I think I figured out the middle question.

I'm having issues with the other two now.

PROBLEM #1:

Recall that the env command provides a list of various environment variables available to you. Two of those variables are PWD, which is your current directory, and HOME, which is your home directory. Write a script named script7.sh to test to see if you are currently in your home directory. This will be true if $PWD is equal to $HOME. Output the result.

PROBLEM #2:

Code:

#I'm given a code string of:

for word in $( cat $filename )
do
echo $word
done

I'm directed to write a script named script9.sh where, in place of $filename, you pass in a parameter of a text file’s name. This will be referenced as $1 in the script. Pass in a second parameter, a string, which will be referenced as $2. Using the for loop with cat, count the number of occurrences of the string ($2) in the file. Output the string ($2) and the number of times you found it in the file. Test this out on a few different text files to make sure it works. Include your script script9.sh as your answer to this problem.

dirname

basename(1)							   User Commands						       basename(1)

NAME

       basename, dirname - deliver portions of path names

SYNOPSIS

       /usr/bin/basename string [suffix]

       /usr/xpg4/bin/basename string [suffix]

       dirname string

DESCRIPTION

       The  basename  utility deletes any prefix ending in / and the suffix (if present in string) from string, and prints the result on the stan-
       dard output. It is normally used inside substitution marks (``) within shell procedures.

   /usr/bin
       The suffix is a pattern defined on the expr(1) manual page.

   /usr/xpg4/bin
       The suffix is a string with no special significance attached to	any of the characters it contains.

       The dirname utility delivers all but the last level of the path name in string.

EXAMPLES

       Example 1: Setting environment variables

       The following example, invoked with the argument /home/sms/personal/mail sets the environment variable NAME to the file named mail and  the
       environment variable MYMAILPATH to the string  /home/sms/personal:

       example% NAME=`basename $HOME/personal/mail`
       example% MYMAILPATH=`dirname $HOME/personal/mail`

       Example 2: Compiling a file and moving the output

       This  shell  procedure,	invoked  with  the argument /usr/src/bin/cat.c, compiles the named file and moves the output to cat in the current
       directory:

       example% cc $1
       example% mv a.out `basename $1 .c`

ENVIRONMENT VARIABLES

       See environ(5) for descriptions of the following environment variables that affect  the execution of basename and  dirname:  LANG,  LC_ALL,
       LC_CTYPE, LC_MESSAGES, and NLSPATH.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred.
