From: Danish on 3 Oct 2009 08:15 Hi, Please tell me how to remove the non printing characters from a test file. I am trying to use te dos2unix utility under solaris but my user has not been given permission of the /tmp directory because of which the utility is not able to create a temporary file. I suspect it requires the access to create a file. cat -v file prints the non printing characters but im not able to figure out how to redirect the file to a new file (if thats possible) so that it doesnt contain the non printing charaters. help will be appreciated a lot thanks

Maybe this: tr -cd '[:print:]\n' < test_file
