Removing Control M character

Shell Programming and Scripting
1

Hi,

I'm using MKS tool kit to execute KSH on windows and samba to move files to unix from windows.

My script is appending header record for the data file.

I'm using

echo "$header" > $SambaFilename
cat $windowsfile >> $SambaFilename

But after execution of script ,The file in Unix conatins Control M character at the end of header record. How to eliminate this character.

Please advice!

# IN UNIX ENVIRONMENT: convert DOS newlines (CR/LF) to Unix format.
sed 's/.$//'               # assumes that all lines end with CR/LF
sed 's/^M$//'              # in bash/tcsh, press Ctrl-V then Ctrl-M
sed 's/\x0D$//'            # works on ssed, gsed 3.02.80 or higher
# IN UNIX ENVIRONMENT: convert Unix newlines (LF) to DOS format.
sed "s/$/`echo -e \\\r`/"            # command line under ksh
sed 's/$'"/`echo \\\r`/"             # command line under bash
sed "s/$/`echo \\\r`/"               # command line under zsh
sed 's/$/\r/'                        # gsed 3.02.80 or higher
# IN DOS ENVIRONMENT: convert Unix newlines (LF) to DOS format.
sed "s/$//"                          # method 1
sed -n p                             # method 2
