I'd prefer something like email user@example -s test -a "$(ls -1 *.pdf | tr '\n' ',' )" < sample.txt Which would only fail if the file name had embedded newlines. I suppose `email' probably wouldn't be able to process a file with an embedded comma in the name one way or the other, but I find this sort of solution more portable than messing with IFS. ~Matt -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
