UNIX for Dummies Questions & Answers

Can anyone help with these scripts? Im new to this and struggling. Thank you for your help.

Pre-requisites

Create a file with x amount of lines in it, the content of your choice. (Have already done this)

Script 1

Write a script that takes two arguments. The first being a line of text, the second being your newly created file. The script should take the first argument and insert it into the very top ( the first line) of the file named in your second argument.

Note! The file must retain the original name

Once complete save the script.


Script 2

Take a copy and amend the above script so that it now inserts the first argument into the middle of the file.

Note! Again the original file must retain it original name

Please make sure that you have read our rules. And note:

I have a script that takes two arguments.
The first argument is a string and the second argument is the name of a file.
The script inserts the string into the first line of the file and then saves it.
The problem im having is that it is saving the wrong message to the file.

e.g. File1 has the following data:
Line1
Line2

I invoke the script as follows.

./Script1 Hello File1


Script1 contains the following data:

cat $2 > tempFile
MESSAGE=$1
awk ' NR==1 { printf "%s\n", $MESSAGE } { printf $0 "\n" } ' tempFile > $2
rm tempFile


The result should be:
Hello
Line1
Line2

But I am getting the following result:
Line1
Line1
Line2


Any ideas on what i am doing wrong?

Thank you.
