Question

Copy/Paste your script from 5b here.

4. Let's look at a more complicated script executable. a. Write the following as script6.sh and change its permissions to count for num in d do if num eq 100 then count (count+1) done echo The number 10 was found $count times What is the output? Run the script as ./script6.sh 10 20 30 10 40 20 50 10 60 <enter Summarize what the script does r using the read command. The following script inputs bl Values can be input b information from the user and outputs it /bin/bash. Enter your name echo read name echo Hello $name that Note that the -n in the echo statement forces echo to not output a new line character s Enter your name and the input appear on the same line. To provide some spaces after name: we use the quote marks in the echo statement. Modify script6.sh from 4a to output a message to the user asking them to specify a target value to compare with using an echo statement, and then input a value from the user using a read statement. Both of these statements must appear before the for loop. Store the user's input value in a variable called target. Now, instead of comparing num to 10, compare num to target. Run the script as you did in 4a, but when asked, enter the value 20. If you did not get the right answer (2), check your script to see if you can figure out what is wrong. Try your script out with different target values (10, 40, 80). When it runs correctly for all of these, copy the script into your answer file. Exit vi 5. The for loop can be used to iterate through more than just the current directory or the list of parameters. It can iterate over the result of any Linux command. Recall the cat command outputs the contents of a file. Using this in a for loop allows you to iterate over each string found in the file Strings are delineated with white spaces (that is, Linux will break up the file into strings based on separating at white space blanks, tabs, returns The following code will output all of the words found in $filename, each word on a separate line for word in cat $filename echo $word. done Write new script, script7.sh, which receives two parameters. The first a file's name ($1 $filename) and the second is a word you want to search for ($2) instead of nside the for loop, instead of echo word, use an if ement to compare $2 to $word. If they are equal, add one to a variable COUNT. Before the for loop, initialize COUNT to o and after the for loop

5 b)

#!/bin/bash

args=$#
count=0
if [ $args -gt 1 ]
then
        for word in $(cat $1)
        do
                if [ $word == $2 ]
                then
                        count=$((count +1))
                fi
        done
                printf "Total : "$count" Words !!\n"
else
        printf "Wrong Arguments\nUsage : "$0" arg1 arg2\n"
fi
