.Sh NAME

.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.
