Question

Hello, I am attempting to write a basic shell script using bash. It will need to print the user, host, time, and date. It will need to take user input for a txt file to be searched and create a new file to save the results. It must print the number of lines and characters in the text. The user will need to enter three words to be searched, and the number of occurrences of those words in the text will be reported. Then, a comparison will be made displaying the words in order from greatest to least.

I am running putty on windows and using the pico editor. If anyone could help me get started I would greatly appreciate it. Thank you.

#!/bin/bash

echo "Username: " `whoami`
echo "Host: " `hostname`
echo "Date & Time: " `date`

echo
echo "Enter file name to search "
read fn

echo
echo "Number of lines in file $fn are : " `wc -l $fn`
echo "Number of characters in file $fn are: " `wc -c $fn`

echo
echo "Enter three word to search in file $fn 1 : "
read sr1

echo
echo "Enter three word to search in file $fn 2 : "
read sr2

echo
echo "Enter three word to search in file $fn 3 : "
read sr3

result1=`grep $sr1 $fn -o | wc -l`
result2=`grep $sr2 $fn -o | wc -l`
result3=`grep $sr3 $fn -o | wc -l`

echo
echo "result 1 of word $sr1 : " $result1 > result.txt
echo "result 2 of word $sr2 : " $result2 >> result.txt
echo "result 3 of word $sr3 : " $result3 >> result.txt

cat result.txt | sort -r

rm -rf result.txt
