2. (20 points) We want a Bash script which will take a list of filenames on the command line and print out how many lines are in each file. For each of the following scripts, indicate whether it works. If it does not, mark the minimum changes need to fix it. (Note: output format is not important.) Script A Works as is. #!/bin/bash for file in $* do done wc -1 $file Needs fixing. Script B Works as is. Needs fixing. #!/bin/bash for file in $@ do echo -n "$file" grep -c $file done Script C Works as is. Needs fixing. #!/bin/bash for file in $0 do done echo -n "$file" tr dc ' ' $file | wc -1 Script D Works as is. Needs fixing. #!/bin/bash for file in $ do done echo -n "$file" awk 'END { print NR } $file
