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, show how to fix it by changing the fewest characters possible. $($Note: output format is not important.$)$

Script A

Works as is$.$ Needs fixing.

$\backslash$#$!/$bin$/$bash

for file in $\backslash$$$\backslash$#

do

wc $-$l $\backslash$$file

done

Script C

Works as is$.$ Needs fixing.

$\backslash$#$!/$bin$/$bash

for file in $\backslash (\backslash$$ $\backslash$mathbb$\{$Q$\}\backslash )$

do

echo $-$n $"\backslash$$file $"$

tr $-$dc $\text{'}\backslash (\backslash$backslash $\backslash$mathrm$\{$n$\}\backslash )\text{'}<mtext></mtext><mi>\backslash </mi>$$file $|$ wc $-$c

done

Script B

Works as is$.$ Needs fixing.

$\backslash$#$!/$bin$/$bash

for file in $\backslash$$$6$

do

echo $-$n $"\backslash$$file"

grep $-$c $\text{'},\backslash$$file

done

Script D

Works as is$.$ Needs fixing.

$\backslash$#$!/$bin$/$bash

for file in $\backslash$$$*$

do

echo $-$n $"\backslash$$file $"$

awk 'END $\backslash \{$ print NR $\backslash \}\text{'}\backslash$$file

done
