Remove carriage return in Unix

Question

What is the simplest way to remove all the carriage returns \\r from a file in Unix?

Answer 1

I made this shell-script to remove the \r character. It works in solaris and red-hat:

#!/bin/ksh

LOCALPATH=/Any_PATH

for File in `ls ${LOCALPATH}`
do
   ARCACT=${LOCALPATH}/${File}
   od -bc ${ARCACT}|sed -n 'p;n'|sed 's/015/012/g'|awk '{$1=""; print $0}'|sed 's/ /\\/g'|awk '{printf $0;}'>${ARCACT}.TMP
   printf "`cat ${ARCACT}.TMP`"|sed '/^$/d'>${ARCACT}
   rm ${ARCACT}.TMP
done

exit 0
