Hi All,
I need to remove control m character from a file.
Steps which i am doing in shell script are:
1) We are comparing the header of the file to the database table header
Here the file header has control-m characters. How do i remove it.
Please help. Below are the steps i am using, but is not working out.
v_header=`sed 1q $v_sftphomedir/$v_finalsourcefile`
echo $v_header |tr -d '\015' > v_avilableheader
or
sed 's/^M//g' $v_header
Please help.

If you copy a file created or modified in Windows or DOS to a Linux/Unix file system, you sometimes find ^M characters at the end of each line.
try to use dos2unix / unix2dos.
Regards

mincdiff - report differences between minc files SYNOPSIS
mincdiff [-header|-body] [-l] [diff options] file1 file2 DESCRIPTION
The mincdiff shell script compares two minc files by running diff(1) on the headers of the two minc files, and cmp(1) on the image vari- able. You can view only the header differences using -header or only the body (image variable) differences using -body. The option -l is passed on to cmp of the image variable. Any unrecognized options (e.g. -u) are passed verbatim to the diff of the headers. OPTIONS
-header Compare only the headers of the two files. -body Compare only the image data of the two files. -l Print the byte offset in decimal and the byte value in octal for each difference encountered in the image variable. AUTHOR
