Homework & Coursework Questions

1. The problem statement, all variables and given/known data:
write a script asciiFix.sh that takes an arbitrary number of file paths from the command line and carries out the same analysis on each one. If a file is not Windows ASCII, your script should do nothing to it. For each file that is Windows ASCII, your script should print the message: converting _fileName_
and should then convert the CR/LF line terminators in that file to Unix-style LF line terminators.



The attempts I have tried do not remove the ^M from the file. The script should be able to handle many file which I believe I can do by "$file"

2. Relevant commands, code, scripts, algorithms:

For example:
cp ~cs252/Assignments/ftpAsst/d3.dat wintest.txt ./asciiFix.sh /usr/share/dict/words wintest.txt fileType.sh converting wintest.txt

3. The attempts at a solution (include all code and scripts):

Code:

#!/bin/sh
file=$1
if file "$@" | grep "ASCII text, with CRLF";then
  echo "converting $file"
  sed -i 's/^M//g' "$file"
fi

I have also tried this

Code:

#!/bin/sh 
for file in "$@" 
do         
if file $file | grep "ASCII text, with CRLF"; then 
                echo "converting $file" 
                sed -i 's/^M//g' $file 
        fi   
done
