Shell Scripting is Fun

Shell Scripting Coding Problem

Problem: Write a shell script that accepts a name from the user and creates a directory by that name, then creates a text file in that directory and stores the data accepted from user (till the singlecharacter Q is given), and displays the number of characters stored in the file.

Solution: 

#start

#!/bin/bash

echo -n "Enter a name to create a directory with: "

read d

mkdir $d

cd $d

echo -n "Enter a name to create a text-file with: "

read f

if [ -f $f ]

then

  rm $f

fi

touch $f

count=0

echo "Enter data for text-file $f"

read -n 1 a

while [ "$a" != "Q" ]

do

  echo -n  -e "$a" >> $f

  count=$(( $count + 1 ))

  read -n 1 a

done

echo

echo -n "Number of characters in $f is: $count"

#end
