hey thanks a lot its working :-)

In vi, type the following :%s/ at this point, press ctrl key, press v, release v, press m, release m and ctrl. Now continue the substitution command by further typing //g

Hi,

i am able to run the above command successfully.

Code:

sed -i 'sed -i 's/^M//g' ps6.txt

--> if i type this command manually then its working.


but if i copy paste the above command in any other directory the its not working

and i want write the same code in shellscript like below

Code:

#!/bin/bash
clear
cd /home/user01/trial1
sed -i 's/^M//g' $inPutFile
rdCount=0;
while read myline

then the sed command is not working here. can you please give me the solution because each time i cant type this command..


Thanks

Its working thanks

The longer-term solution is to always use Text mode FTP when transferring text files from a Microsoft platform to a unix platform. A Microsoft text file has every line terminated with two characters "carriage-return" then "line-feed", whereas a unix text file has every line terminated with one character "line-feed".

In your script a quick fix is to filter the input stream with "tr" to remove the unwanted carriage-return characters.

Code:

#! /bin/bash
clear
rdCount=0;
cat ps5.txt | tr -d '\r' | while read myline
do
  if [ -z "${myline}" ]; then
    echo "line is empty"
  else
   echo $myline
   let rdCount=$rdCount+1
  fi
done
echo "COUNT=$rdCount"

Not sure why you are posting the uncorrected script following your previous thread.
