Question Variables into SED or AWK and multiple commands
Hello I am hoping you may help.

I am not sure how to go about this exactly, I know the tools but not sure how to make them work together.

I have two SED commands that I would like to run in a shell script. I would like to take
the manual input of a user (types in when prompted) to be used as the variables.

Firstly I am not sure how to build the script with cat or loop statements
Secondly how to place a variable inside a SED or NAWK statement so it can be used by those commands.
Thirdly how to produce a temporary file that is date-stamped.

I have a general summary of what I am trying to do below.
#!/usr/bin/
echo "enter name of file" (variable AAAA)
echo "enter first search string1 (variable yyyy)
echo " enter a second search string that searches the file along with string1 ? (variable zzzz)
user types yes, then
enter data
user types no,
then continue with command. sed (filename) variableAAAA > newfilename (newfile with date and time stamp = testfileddmmyyhhmm)
wait 3 seconds
then newfilename sed -e '/./{H;$!d;}' -e 'x;/variableyyyy/'d'
end

Just learning this and hoping you may help.
Thankyou
