.Dd 2015-10-08 .Dt UUDECODE 1 .Os sbase .Sh NAME .Nm uudecode .Nd decode a uuencoded file .Sh SYNOPSIS .Nm .Op Fl m .Op Fl o Ar output .Op Ar file .Sh DESCRIPTION .Nm reads .Ar file and writes a decoded version to the file specified in the uuencoded header. In case the file already exists, it is truncated. Otherwise a new file is created. The permissions of the created/accessed file are changed to reflect the mode in the header. If no .Ar file is given .Nm reads from stdin. .Sh OPTIONS .Bl -tag -width Ds .It Fl m Use Base64 for decoding. .It Fl o Ar output Write to .Ar output rather than the file specified in the header. .El .Sh IMPLEMENTATION NOTES For safety uudecode operates on regular files and stdout only. Trying to uudecode to a link, directory, or special file yields an error. .Sh SEE ALSO .Xr uuencode 1 .Sh STANDARDS The .Nm utility is compliant with the .St -p1003.1-2013 specification. .Pp The .Op Fl m flag is an extension to that specification.
