Shell Programming and Scripting

Executing the commands i get the correct line count if i want to display all the lines that contain the word Another what command can i use..

Which of the command have you used?

grep -c Another filename

grep -i "Another" filename | wc -l

grep -cw 'Another' filename

grep -c Another filename | wc -w

tr -cs 'A-Za-z' '\n' < filename | grep -c "Another"

These are the commands which i used but this all detects only the number i don't get the list of lines that contains the word Another..

A few pointers:-

My file is ss.txt

Another instance started
Another instance started
Another instance started
Another instance started
No instance started
No instance started
No instance started
No instance started

If i use shell script program as this

Code:

#!/bin/sh
t=0
#temp=0
echo "Enter filename"
read f1
if [ -f $f1 ]
then
echo "1.count char,words,lines"
echo "2.particular word to find in file"
echo "3.exit"
echo "Enter ur choice?"
read ch
case $ch in
1) wc -c $f1
    echo "characters"
    wc -w $f1
    echo "words"
    wc -l $f1
    echo "lines" ;;
2) echo "Enter the word whose occurence has to be found"
    read c
    t='echo $f1 | wc -c'
    echo $t ;;
3) exit ;;
esac
else
echo "File does not exist"
fi

If i run this code i get the following output
i could get the option 2 correct that is word occurence is not correct

i get like
Enter filename
ss.txt
1.count char,words,lines
2.particular word in file
3.exit
Enter ur choice?
1
180 ss.txt
characters
24 ss.txt
words
8 ss.txt
lines

This i get correctly but for choice 2 i get like
Enter filename
ss.txt
1.count char,words,lines
2.particular word in file
3.exit
Enter ur choice?
2
Enter the word whose occurence has to be found
Another
0


See i get zero here but output should be 4

Let's look at option 2 in the switch case.

Code:

2) echo "Enter the word whose occurence has to be found"
    read c
    t='echo $f1 | wc -c'
    echo $t ;;

There is an attent to read from input read c but nothing is done with $c which contain the chosen word. Instead there's a byte count of whatever echo $f1

Can u say me how could i change it..
