Complete NOOB need help

[gham]

I am a complete noob to linux and shell scripting please help

this is what I am trying to do
1. Create a script that takes 1 argument being a file, read the inputted file, and look for occurrences of the current user who is executing the script. On finding an occurrence of the username take that line and append it to a file and display a line number and a bracket against the saved line

efforts sofar

#!/bin/bash
echo "filename"
read myvar
grep $USER $myvar > results.txt
nl results.txt
 

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


thanks in advancefor any help

A scratch code might be

#!/bin/sh
 
cat $1 | grep $USER >> files.txt
cat files.txt | grep $USER

A scratch code might be

#!/bin/sh
 
cat $1 | grep $USER >> files.txt
cat files.txt | grep $USER
 
 

don't teach a noob the "wrong" things. both the above cats are useless. grep takes in a file as input.

grep $USER $1 >> files.txt
grep $USER files.txt
