Are you using any Windows Editor to save files to unix ?
# 3  
Old 01-28-2010
no, i am getting this file from windows server via connect:direct.

If you cannot trace how those characters got there in the first place (change a file transfer setting), perhaps simply deleting the first character might help?
Code:
sed 's/.//' infile > outfile

Code:
do2unix infile infile
