Usage is simple…
tnef: [options] [FILE] -f FILE,--file=FILE use FILE as input ('-' == stdin) -C DIR, --directory=DIR unpack files into DIR -x SIZE --maxsize=SIZE limit maximum size of extracted archive (bytes) -t, --list list files, do not extract --list-with-mime-types list files and mime-types, do not extract -w, --interactive ask for confirmation for every action --confirmation same as -w --overwrite Overwrite existing files --number-backups Instead of overwriting file FOO, create FOO.n instead --use-paths Use pathnames for files if found in the TNEF file (for security reasons paths to included files are ignored by default) --save-rtf[=FILE] [DEPRECATED] Save the RTF message body to a file --save-body[=FILE] Save the message body to a file -h, --help show this message -K, --ignore-checksum Ignore any checksum error (warn only) -V, --version display version and copyright -v, --verbose produce verbose output --debug produce a lot of output If FILE is not specified standard input is used
