uuencode converts a binary file, named bin_file, into a ascii file, named asc_file. you type, uuencode bin_file bin_file > asc_file ( please note that bin_file is typed twice. ) This asc_file then can be transmitted via email. To convert the ascii file back to original binary file, you type, uudecode asc_file and a binary file bin_file will appear in the current directory. If you are happy with above explanation, then stop. Otherwise read on: You can use uuencode bin_file1 bin_file2 > asc_file bin_file1 is the filename that you want to uuencode to ascii file and bin_file2 is the filename that you want to appear after uudecoding the ascii file. xiaofei for ftp-admin@ifcss.org
